Is there any way to prompt you whether to turn off the computer when it is turned off?

1. Playing pc games for a long time will accelerate the warming of cpu.

2. Thermal conductive silicone grease 2. The CPU and radiator are aged and hardened, removed and coated with new thermal conductive silicone grease.

3. Remove the dust from the radiator and fan.

4. Turn off useless programs when playing games, so that the game is smoother and the cpu burden is less.

5. Adjust the fan combination of the chassis to create a good cooling channel.

6. To cope with the temperature in summer, open all the covers and put them in a ventilated place (don't want to change new parts,

Lazy cleaning, that's all. :-))

Your phenomenon is probably due to the high CPU temperature. Especially the weather is getting hotter and hotter recently, which is normal. This way, the next time you crash, you can feel whether the heat sink of your CPU is very hot ... If so, you can quickly replace the fan. ...

There is also the case that the graphics card is overheated, so you have to check whether the fan of your graphics card is broken and the heat dissipation is not good. ...

Such a problem is rarely a power supply problem. If so, then one of the capacitors in your power supply is broken. But this situation will not be too much, so you should check whether the CPU and graphics card are overheated first. If all these possibilities are ruled out, then consider the power supply.

If you want to quickly judge whether there is a power problem, you can unplug the power supply after turning it off, then press the power-on key to discharge the remaining power in the power supply, then plug it in again and turn it on. If you can turn it on immediately without waiting, there is a great possibility of power failure. If it takes a while to boot, it may be that your CPU is not cooling well and is still at a dangerous temperature, so it is not allowed to boot.

If it is a black screen after working for a period of time, the host power supply and display indicator light are on, and it can continue to work after shutting down for a period of time, which is caused by the wrong reset signal generated by the host system reset circuit of the host power supply or the poor thermal stability of IC (integrated circuit), R (resistor) and C (capacitor) of PG circuit;

If the rotation of the starting fan stops after the black screen, and there is no output voltage, the host power supply protection circuit is working. The main reason is overload or light load (poor contact at the load end), which leads to the action of the protection circuit.

There is too much dust in the power supply, which leads to poor contact. It can be cleaned up.

1。 Check the CPU temperature in Bios to see if it is caused by too high temperature in real time.

2。 It has nothing to do with the hard disk.

3。 If there is a problem with the integrated graphics card, it is the motherboard. There is usually no problem.

4。 Maybe, but we can't rule out hardware reasons, such as poor heat dissipation and memory damage.

If it can't be solved, then see if there is anything wrong with your electricity environment. For example, turning on the TV and air conditioning, the load is too heavy, leading to a sudden restart of the computer.

It is also possible that there is no abnormality in the motherboard, and observe whether there is physical damage to the motherboard.
