When the computer is first turned on, it always has a blue screen or restarts automatically. What's going on here?

When the computer is first turned on, it always has a blue screen or restarts automatically. What's going on here? Reasons for automatic restart of computer:

1. If the application software was downloaded or executed before the restart, it may be the program software that caused the restart. Just uninstall the program software and then reinstall it. If the fault still exists, it indicates that there is an error in the system.

2. Press F8 to enter safe mode, then exit, and then enter normal mode. You can also use the system restore function that comes with the system to restore. If troubleshooting is restarted, it is a restart caused by system file corruption.

3, check the motherboard, motherboard aging, capacitor failure or Explosicum, motherboard and chassis backplane short circuit may lead to restart, you can take the motherboard out of the chassis for inspection or testing, and then check whether the silica gel at the bottom of the CPU fan heat sink is dry, if so, clean the silica gel on the CPU fan, and then repaint the silica gel. Then check whether the fan of CPU rotates and the temperature of CPU is normal.

4. If the fault still exists, check the power supply. The power supply is of poor quality, aging or low power, which can not meet the power supply requirements of computer accessories. High-power and high-quality power supply can be replaced. If the fault is eliminated, it is a restart fault caused by power supply.

Computer automatic restart solution:

1. Poor cooling of the computer can easily lead to automatic restart of the computer, because the cpu has self-protection function. When heat threatens computer hardware, it will shut down and automatically protect it. If this is the case, it is recommended to put the computer in a dry and cool place and ensure the normal operation of the fan to ensure good heat dissipation of the computer.

2. Secondly, there may be problems with computer software, including computer poisoning, software conflicts or errors. All these may cause the computer to restart automatically. If you want to eliminate software problems, you can prevent viruses first, and then reduce the software running in your computer. Try running the software to see under what circumstances the computer will automatically restart. If you find the software that caused the restart, please download it. If you are still not sure, you can try to charge the system.

3. Computer restart caused by other computer problems, including other computer hardware problems, such as broken hard disk, etc. These problems should be tested by computer hardware testing software. If there is something wrong with the test, you should go to the repair shop for repair immediately.

The computer always restarts automatically. The light keeps flashing when restarting? What's going on here? Upstairs, is the CPU fan not turning or the speed is not enough?

When the startup screen appears, the computer will automatically restart. What's going on here? I hope I can help you:

Usually, there are several reasons for the system to restart and shut down irregularly:

First of all, we must rule out the possibility of pressing the right button of "My Computer". Attribute-> Higher order->; Press "start and repair"->; Uncheck the three options in the System Failure box below. When these three options are cancelled, most people's problems can be solved.

2. If it closes automatically and a dialog box appears, it is probably a virus. Solution: Antivirus.

3.WINDOWS startup program error. If there is an error in the execution of a program when WINDOWS is started by default, the system will restart, and the newly loaded program with errors will restart. If a program in the startup item has a serious error, the system will start again and again. Solution: Press F8 when the system starts, enter the safe mode, select "Startup and Fault Recovery" in the Control Panel-System-High Level, and finally remove the checkmark of "Automatic Restart" under the column of "System Fault".

4. If you use CD-ROM drive or floppy disk drive, you will stop or restart. Or hang an extra hard disk, which will often run out of power. That may be a problem with the power supply. Solution: Replace the power supply.

At present, motherboards generally have temperature protection control chips to prevent CPU from overheating and burning. Sometimes the early warning temperature of CPU in BIOS is set too low, and when the CPU is fully loaded, the temperature exceeds the early warning temperature, and the system will automatically shut down. Of course, due to the poor heat dissipation of the chassis, the CPU temperature is too high to execute stably, which will also lead to the system restart. Solution: Adjust the protection temperature to a suitable temperature in the BIOS to strengthen the heat dissipation of the system.

6. Watching a movie will cause downtime. Nothing will happen after the restart. Nine times out of ten, it's the driver of the graphics card. Solution: Download the most stable driver version.

7. It is quite common that the system will start automatically when a large 3D game or a large number of system programs are executed. Many systems use dual channels. If the quality and performance of the two memories are very different or the electrical stability of their respective memory chips can't meet the requirements of dual channels, then the system may be unstable and restart often fails when executing large programs. Solution: Try to increase the CL value of the memory in the BIOS, such as 2.5 to 3, and reduce the bus speed of the system appropriately for the channel.

After installing the router, the computer always shuts down or restarts automatically. What happened? Is the TP -LK or D -LK used in your router incompatible or 20 yuan? Brother, can you talk to QQ and tell me?

3. If the fault still exists, please use the system that comes with the system to restore it to the state without this fault (or use recovery software to restore the system).

4. If the fault remains, use the system disk to repair it, open the command prompt and enter SFC/SCANNOW(SFC and/) to insert it into the original system disk repair system, and the system will automatically compare and repair it.

5. If the fault still exists, set the optical drive as the first boot device in the BIOS, insert the original system installation disk, and press the R key to select "Repair Installation".

6. If the fault still exists, it is recommended to recharge the operating system. Maintenance method of computer blue screen fault

When the computer has a blue screen failure, repair it according to the following maintenance methods.

(1) First of all, understand the situation of the computer before the blue screen occurs and operate it well. If the computer has a blue screen after overclocking the CPU or memory, the blue screen failure is related to overclocking, as long as the frequency returns to normal.

(2) If the computer is turned on abnormally when reading the CD in the CD-ROM drive, the blue screen fault is caused by misoperation. Usually, this failure may be caused by putting the disc back in the optical drive and then closing the tray of the optical drive.

(3) If the computer has a blue screen when plugging and unplugging equipment, the blue screen fault is related to the plugged and unplugged equipment, and it can be recovered by restarting the computer.

(4) If the computer has a blue screen when using the application software, the blue screen failure may be caused by the application software. Generally, you can uninstall the program software and then reinstall it to troubleshoot; If not, there may be something wrong with the software itself and it cannot be used.

(5) If there is a blue screen after the computer enters the system, there may be many reasons for the blue screen failure, which need to be eliminated step by step. First use anti-virus software to kill virus and eliminate the blue screen failure caused by virus. If the fault is eliminated, it is a blue screen fault caused by the virus.

(6) If it is still the same, restart the computer, and then start the computer in "safe mode". After startup, exit the system and restart to normal mode. If eliminated, it is a blue screen failure caused by a system error.

(7) If the fault is not eliminated, use the backup registry file to restore the Windows registry file to the normal state. If the fault is eliminated, it is a blue screen fault caused by the damage of Windows registry file. If the computer has a blue screen (including game software) when using an application software, the blue screen failure may be caused by this program software. Generally, you can uninstall the program software and reinstall it to troubleshoot. If not, there may be something wrong with the software itself and it cannot be used.

Please repair the blue screen as follows.

1. The program software is incompatible with the system.

2, to the device manager, check whether there are any conflicts between various drivers, and whether there are yellow ones! If the device driver may be incompatible with the system; Then delete the drivers of sound cards, video cards, network cards and other devices, and then install the drivers one by one. After installing each device, restart the computer to check which device's driver caused the failure. After finding out, download the new driver of the faulty equipment and then install it. Then clean up the dust in the computer, clean up the memory, graphics cards and other equipment, and reinstall the memory and other equipment.

3. If the computer has a blue screen when plugging and unplugging electrical equipment, the blue screen fault is related to the plugged and unplugged equipment, and it can be recovered by restarting the computer. If it happens frequently, the device is incompatible with the system. Try replacing hardware or installing USB driver. If the fault remains, don't plug it in, try plugging it in and then turning it on.

Memory fault diagnosis: when it is suspected that the fault is caused by memory problems, you can follow the following steps to diagnose and eliminate it.

1. First, restore the BIOS to the factory default settings, and then start testing.

2. If the fault still exists, then remove the memory, and then clean up the dust on the memory and motherboard to see if the fault is eliminated after cleaning.

3. If the fault remains, wipe the golden finger of the memory with an eraser, and install the boot test after wiping.

4. If the fault still exists, install the memory into another slot and start the test. If the fault disappears, re-check whether the spring piece of the original memory stick is deformed. If there is, just adjust it.

5. If the fault still exists after replacing the memory slot, use the replacement method to detect the memory. When good memory is installed on the motherboard, the fault disappears. May be the fault of the original memory; If the fault persists, there is a problem with the motherboard memory slot. At the same time, install the faulty memory on another good motherboard for testing. If it can be used normally, the memory is incompatible with the motherboard. If the same fault occurs on another motherboard, the memory quality is poor or damaged.

6, graphics card driver failure:

The failure of graphics card driver usually leads to system instability, downtime, screen display, incomplete text and image graphics cards and other failures. The failure of the graphics card driver mainly includes the loss of the graphics card driver, the incompatibility between the graphics card driver and the system, the damage of the graphics card driver, and the inability to install the graphics card driver. If the general graphics card driver fails, first go to the device manager to check whether there is a graphics card driver, and if not, reinstall it. If there is, but there is "!" On the graphics card driver. , indicating that the graphics card driver is installed incorrectly, the driver version is wrong, and the driver is incompatible with the system. Generally, delete the graphics card driver and reinstall it. If there is still "!" After installation. , you can download a new driver installation. If you can't install the graphics driver, there is usually something wrong with the driver or the registry file. Discharge the BIOS battery (restore the BIOS factory default). It is recommended to plug in and out the graphics card and memory, clean it up and polish the golden finger of the graphics card and memory. Unable to start the operating system. Various diagnostic methods are as follows.

First, check whether the operating system has started when the computer is turned on. If there is shutdown, blue screen or automatic restart when the operating system is started, it means that the partition slot table and the hard disk master boot record are normal, and troubleshooting causes such as partition slot table damage, hard disk master boot record damage, hard disk partition slot end flag loss, etc. Then use the following methods for diagnosis.

Step 1: First, start the computer in safe mode to see if it can be started. If it can't start, it may be infected with a virus, lost system files, damaged operating system, damaged hard disk, hardware device conflict or hardware problems. Go to step 4. If the safe mode can be started, it may be that the hardware driver is incompatible with the system, the operating system has a problem or a virus infection.

Step 2: Then run anti-virus software. If there is a virus, it may be caused by it. After antivirus, restart the computer. If it is not normal, you need to reinstall the operating system.

Step 3: If no virus is detected, you can use the "System Recovery" function of the operating system to recover the system. If the system is normal after recovery, the fault is caused by system damage. If the fault still exists, it may be caused by the incompatibility between the device driver and the system; Then delete the drivers of sound cards, video cards, network cards and other devices, and then install the drivers one by one. After installing each device, restart the computer to check which device's driver caused the failure. After finding out, download the new driver of the faulty equipment and then install it.

Step 4: If you can't boot from safe mode, reinstall the operating system with the installation CD. If the operating system can be installed normally, go to step 7; If the operating system installation fails, such as shutdown, blue screen, restart, etc. , it should be caused by hardware problems or poor hardware contact.

Step 5: Then clean up the dust in the computer, clean up the memory, graphics card and other equipment, reinstall the memory and other equipment, and then reinstall the operating system. If the system can be installed normally, it is a fault caused by poor contact.

Step 6: If the system still cannot be installed, it may be a hardware problem. Then use the replacement method to check the hardware failure, and replace the hardware after finding it.

Step 7: If the operating system can be installed normally and the fault disappears after installation, it is a fault caused by system file damage.

Step 8: If the fault still exists after installing the operating system, it may be caused by bad tracks on the hard disk or incompatibility between the device driver and the system. Start the computer in safe mode. If it can't be started, it is the failure caused by the broken hard disk. Then use NDD disk tool to repair the bad track.

Step 9: If the safe mode can be started, it is caused by the incompatibility between the device driver and the system. Then delete the sound card, video card, network card and other devices, and then install the drivers one by one, and check which device's driver caused the failure once. After finding out, download the new driver of the faulty equipment and then install it.

When the computer shuts down, it always restarts itself. What's going on here? How to fix it? I used to do this. . Was attacked by a Trojan horse. . .

Kill directly if you can use anti-virus software.

If not, find out where the Trojan horse is and carefully delete it manually.

You can download an ice blade to see what hidden programs are there.

How is it that the computer automatically restarts as soon as the boot screen passes? What is the reason for the computer to restart automatically? How to prevent it?

First, the software

1. virus

When the "shock wave" virus attacks, it will also prompt the system to start automatically after 60 seconds.

Trojan horse programs remotely control all activities of your computer, including restarting your computer.

Solution: Remove viruses and Trojans, or charge the system.

2. The system file is corrupted.

System files are destroyed, such as KERNEL32.DLL under Win2K when the system is executed, FONTS under Win98 fonts directory and other basic files, which will be forced to restart when the system is started.

Solution: cover the installation or reinstall.

3. Timing software or task planning software works.

If you set a restart or load some working programs in the "scheduled taskbar", then the computer will start again. In this case, we can open the "Start" item, check whether there are unfamiliar execution files or other scheduled work programs, and then overwrite them before starting the check. Of course, we can also directly enter the "Msconfig" command in "Execute" to select the startup item.

Second, the hardware.

1. Chassis power supply is insufficient, DC output is impure, and dynamic response is slow.

Users or installers often ignore the power supply and use cheap power supply, which is one of the biggest suspects that lead to the automatic restart of the system.

① The output power of power supply is insufficient. When executing software that takes up a lot of CPU resources, such as large 3D games, when the CPU needs high power supply, the power supply is overloaded due to insufficient power supply, and the output is stopped. After the power supply stops outputting, the load is lightened and the power supply is resumed. Because the protection/recovery time is very short, the performance given to us is that the host automatically restarts.

② The DC output of power supply is impure, and the digital circuit requires pure DC power supply. When the harmonic content in the DC output of the power supply is too large, the digital circuit will work abnormally, which is manifested by frequent shutdown or restart.

③ The workload of ③③CPU is dynamic, so is the requirement for current, which requires fast dynamic response. Some poor quality power supplies have long dynamic response time, which will also lead to frequent shutdown or restart.

④ Update equipment (high-end graphics card/large hard disk/graphics card). After adding equipment (burner/hard disk), the power exceeds the rated output power of the original power supply, which will lead to frequent shutdown or restart.

Solution: Now replace the high-quality and high-power computer power supply.

2. The thermal stability of the memory is poor, and the chip is damaged or set incorrectly.

The probability of system restart caused by memory problems is relatively high.

① The thermal stability of the memory is poor, and it can work normally when it is turned on. When the memory temperature rises to a certain temperature, it will not work normally, resulting in shutdown or restart.

(2) When the memory chip is slightly damaged, you can pass the self-check (setting fast startup to detect the memory incompletely), or you can enter the ordinary desktop to run normally, and restart or shut down when executing some software with high I/O throughput (media playback, games, plane /3D drawing).

Solution: Replace the memory.

③ Setting the CAS value of the memory too small will also lead to the instability of the memory, leading to the automatic restart of the system. Generally, it is best to use the default settings of BIOS, and don't change them yourself.

3. number three. The CPU temperature is too high or the cache is damaged.

① Too high ①CPU temperature often leads to protective automatic restart. The reason for the high temperature is basically because the chassis and CPU are not well cooled. The reasons for poor heat dissipation of CPU are: low thermal conductivity of radiator material, foreign objects (mostly warranty cards) between radiator and CPU, low fan speed, too much dust on fan and radiator, and so on. Also, the temperature probe under the CPU of the P2/P3 motherboard is damaged or the temperature measuring circuit inside the P4 CPU is damaged. The BIOS on the motherboard has a BUG and temperature measurement is not allowed under certain special circumstances. The CPU protection temperature set in CMOS is too low, which will also cause protection restart.

② The damage of the first-level and second-level cache inside the CPU is a common failure of the CPU. Slightly damaged ones can still be started and can enter the normal desktop for normal operation. When executing some software with high I/O throughput (media playing, games, plane /3D drawing), they will be restarted or closed.

Solution: Overwrite L2 or L 1 cache (L 1) in CMOS, or replace CPU to exclude it.

4. Automatic restart caused by 4. AGP graphics card and PCI card (network card, cat)

① The external card does not work properly or its quality is poor, which leads to the failure of reset signal of AGP/PCI bus and system restart.

(2) There are also cases where the graphics card and network card are loose, resulting in system restart.

5. Automatically restart when the parallel port, serial port and USB interface are connected to a faulty or incompatible external device.

① Peripheral failure or incompatibility, such as printer parallel port damage, one pin short circuit to ground, USB device short circuit, pin definition and signal level incompatibility, etc.

② The jitter of external equipment is too large when it is hot-plugged, resulting in instantaneous short circuit of signal or power supply.

6. The internal circuit or chip of the optical drive is damaged.

The optical drive is broken, mainly because it can't read/write. There are also cases where the host machine suddenly restarts due to the damage of internal circuits or wafers during work. The CD-ROM drive itself is poorly designed, and there is a Bug in FireWare. It also causes a reboot when reading the disc.

7. The reset switch problem on the front panel of the chassis.

The reset key on the front panel of the chassis is actually a normally open switch, and the reset signal on the motherboard is a +5V level signal, which is connected to the reset switch. When the switch is closed, the +5V level is grounded, and the signal level drops to 0V, which triggers the system to reset and restart, and the reset switch returns to the normally open position, at which time the reset signal returns to the +5V level. If the reset key is damaged, the switch is always in the closed position, and the reset signal is always 0V, the system will not be able to power on the self-test. When the elasticity of the reset switch is weakened and the button is not easy to bounce when pressed, the switch will be easily closed with a slight vibration. Resulting in a system reset and restart.

Solution: Replace the reset switch.

There is also a short circuit in the reset switch lead in the chassis, which leads to the automatic restart of the host.

8. Motherboard failure

It is rare for the motherboard to cause an automatic restart. Generally, the circuit related to reset is faulty; Socket and slot have virtual welding and poor contact; Individual chips, capacitors and other components are damaged.

Third, other reasons.

1. The power supply voltage is unstable.

① The working voltage range of computer switching power supply is generally 170V-240V. When the power supply voltage is lower than 170V, the computer will automatically restart or shut down.

Solution: add voltage regulator (not UPS) or 130-260 V wide switching power supply.

(2) If high-power appliances such as computers, air conditioners and refrigerators use patch panels, when these appliances are started, the voltage supplied to computers will be greatly affected, which is often manifested in system restart.

The solution is to separate their power cords.

2. Strong magnetic interference

Don't underestimate electromagnetic interference. Many times, the shutdown and restart of our computer are also caused by interference. These disturbances not only come from the internal CPU fan, chassis fan, graphics card fan, graphics card, motherboard and hard disk, but also from the external power cord, inverter air conditioner and even large equipment such as cars. If the interference efficiency of our host is poor or the shielding is poor, the host will restart unexpectedly or stop frequently.

3. Incorrect connection of AC power cord.

Some users directly ground the zero line of the power supply line (not the zero line of the electric energy meter), which leads to automatic restart, because the interference signal is introduced from the ground line.

4. The plug-in or power socket is of poor quality and poor contact.

After the power socket is used for a period of time, the elasticity of the reed slowly loses, which leads to poor contact between the plug and the reed, constant change of resistance and fluctuation of current, and the system will naturally be unstable. Once the current fails to meet the minimum requirements for system implementation, the computer will restart. The solution is to buy a good socket with qualified quality.

5. Too much dust causes the reset line of the motherboard to be short-circuited and automatically restarted.

Fourth, some examples.

1.Example of CPU L2 cache corruption

A compatible machine configured a few years ago: K6-2 200MHz CPU, with VX-Pro+ chipset as the motherboard and two 16MB 72 EDO memories.

Windows 98 operating system. After the blue sky and white clouds appear, it will automatically restart, and it can't enter the safe mode, but only enter the MS-DOS mode. I guess it's more likely that the computer was restarted because of the quality problem of the memory module, so I replaced the memory module of the same model first, and the fault remained unchanged. Changing the power supply still doesn't solve the problem. Finally, only the motherboard, CPU and graphics card are left. I tried the graphics card, but there was no problem. I couldn't find the old motherboard that could hold K6-2 200MHz CPU, so I had to give up.

At that time, I also suspected that there might be something wrong with the BIOS settings. I tried to restore to the default values and failed to solve the problem. A few days later, when I was playing computer again, I accidentally entered the BIOS and set the internal cache of CPU to Disable. After saving and exiting, I restarted, and the system can actually start! It is estimated that there is something wrong with the CPU cache, so set the cache to open state and start the computer. Sure enough, the system can't start normally again. Because the efficiency of CPU is greatly reduced after the cache is turned off, Windows 98 is much slower than before when starting and executing programs. Finally, a new CPU will solve the problem.

2. Example of power failure

The computer in the place where the author works has to be turned on every day (because there are many people surfing the Internet), and it is common to leave it on for ten days and a half months. Under such high working intensity, the failure rate of hardware equipment is also very high.

Symptoms: Two compatible computers, one CPU is Athlon XP 1700+, the other CPU is P4 1.7GHz, and the host power supply is Century Star. When the computer runs at full capacity for a period of time (at this time, the CPU utilization rate is kept at 100%, and the hard disk is also reading and writing a lot of data), it will be restarted automatically frequently. When one of them connects a 60GB hard drive and an 80GB hard drive, the power supply is insufficient.

Fault analysis and treatment: Because these two computers are normally used for general work such as file editing and surfing the Internet, problems will only occur when a large number of calculations are carried out. At first it was suspected that the CPU temperature was too high, but the test showed that the temperature was normal. Check the hard disk and find that one of the hard disks has bad tracks, but the fault still exists after replacing the hard disk charging system. It seems that the bad track of hard disk is probably caused by frequent abnormal restart of computer. After replacing the new power supply, the fault disappeared.

When two old power supplies were disassembled, it was found that two electrolytic capacitors with the same model (3300μF/ 10V) had yellowish brown granular condensate on the top of one power supply, and two different models (1000μF/ 16V, 3300μF/ 16V) were also found in the other power supply. After spending money to buy the same type of capacitor replacement in the electronic market, they all returned to normal after testing. Here is a reminder, never connect the positive and negative poles of the capacitor upside down! Through analysis, it is found that the power grid of the author's unit is often suddenly cut off due to maintenance or improper use of electricity, which leads to capacitor breakdown on accessories. A motherboard also went on strike after a sudden power failure. After inspection, it was found that several large electrolytic capacitors were damaged and leaked, and they returned to normal after replacing the capacitors.

3. Examples of poor graphics card contact

Trouble: My friend's computer is equipped with BenQ 77G monitor, Gigabit 8IRX motherboard, P4 1.6G CPU, 80G hard disk, 3000 video card of small movie producer, polar cloud waterfall cat and AC97 sound card of motherboard. Because the house is decorated and the computer has to be moved, all the connections behind the computer have to be removed. Later, after I connected the line myself, the computer couldn't start. The computer self-test is normal. After flashing the motherboard logo, the WINDOWS 98 startup screen appears, and then the cursor flashes. Everything is normal, but when I was about to enter the system, the computer suddenly restarted with a beep, which happened several times.

Fault analysis: The author's friend is a pure "novice", and the preliminary judgment may be a general wiring problem, which is probably caused by the mouse and keyboard being connected backwards. First, I checked the computer wiring. No problem. Could it be that the wiring is loose? Reconnect all computers.

The fault remains the same. When starting, select safe mode to enter the system and execute normally. After the restart, enter the BIOS to check the CPU temperature. If it is within the normal range, it is ruled out that the CPU is overheated and leads to the restart. My friend didn't install new hardware either, so I ruled out the restart phenomenon caused by insufficient power supply. The reasons for the failure may be as follows

The next four aspects: first, software conflict; Second, the display resolution or refresh rate is set higher than the rated value; The third is the conflict between the graphics card and other hardware, or the driving problem; Fourth, the graphics card is faulty.

Troubleshooting: Ask a friend what he did to the machine before it broke down. My friend said that it had been used well before disassembling the machine, and no new software was installed. There is no clue, only from the above four possible reasons for failure. After restarting, enter the safe mode, execute msconfig command, and delete all startup items that are not needed by the operating system. After restarting, the fault still exists. It seems that it is not caused by software installation. Let's see if the resolution and refresh rate are too high. In safe mode, delete and restart the monitor, and the fault still exists. Finally, the problem focuses on the graphics card. Enter the safe mode again, delete the graphics card driver, skip the installation of the graphics card driver and enter the normal startup mode after restarting. It seems to be a driver problem or a failure caused by the conflict between the graphics card and other hardware. Download a new driver and see if it can solve this problem. Dial-up internet, the machine suddenly restarts, is the cat broken, too? What should I do? Is it really over? This computer can't be started because it was disassembled. The graphics card and the cat won't break down because of moving the machine, will they? Think of moving the computer, is it because the graphics card was knocked loose when disassembling the computer, resulting in poor contact and failure? With the idea of one last attempt, I opened the case, pulled out the graphics card and the cat, plugged it in again, installed the graphics card driver, restarted it, and even saw a beautiful desktop. I tried to dial, no problem. The fault has been eliminated. It turned out that the fault was caused by poor contact of the graphics card.

Summary: The computer can't enter the system due to the poor contact of the above graphics cards, which is similar to the symptoms of graphics card failure. If you don't start with small problems, it will be really difficult to solve for a while, and you may even suspect that it is a hardware failure, which will be very troublesome.

How is it that the computer always has a blue screen or always restarts automatically when it is turned on? Recommend recharging the system. If it still doesn't work after recharging, check whether the memory is compatible.

When I play Tai Chi Panda 2, there is always a blue screen or a card machine to restart. What happened? Is your computer configuration too low?

See if the computer configuration can meet the game configuration standards.

If it is not a hardware problem, it may be caused by high memory occupation at that time.
