What should I do if the desktop computer starts slowly?

Slow startup of computers is a common problem now. Let me tell you something about it.

Solution to slow startup of desktop computer

First, optimize the system.

1, reduce unnecessary startup items and reduce the burden on the computer. Many softwares "like" to start from system startup. Disabling the startup item is one of the most effective and economical ways to improve the startup speed.

Windows 8 can run directly in the work manager, and other versions of Windows operating system run in msconfig startup item management. If you don't know, it is recommended to use third-party optimization software for optimization.

2, disable unnecessary services, some services we may never use, disabling some services will also reduce the burden on the computer.

Right-click Computer → Management → Services to disable unnecessary services. If you don't know them, it is recommended to use third-party optimization software for optimization.

3. Clean up garbage files reasonably.

Some optimization software frequently prompts how many junk files there are. In fact, cleaning up the garbage often may slow down the computer startup, because some files are not junk files, and the files read by the computer in advance will speed up the computer startup to a certain extent.

Some residual registry files have a great influence on the boot speed, and some computer management software is difficult to remove. Need to manually clear, press winkey+r, and enter regedit enter in the execution window. Open the registry file, and query and delete through the keywords of the software name. It should be noted that deleting the registry file has certain risks, and the principle of not deleting it is uncertain.

Second, kill the virus.

1. If there are malicious programs in the computer, the computer will become extremely slow whether it is turned on or running normally. Therefore, the poisoned computer will have a qualitative improvement after antivirus.

Generally, there are three antivirus methods: ① conventional antivirus, ② safe mode antivirus and ③PE system antivirus.

2. For the virus that can't be killed, you can use the recharge system.

Third, choose the correct operating system.

1. XP system is recommended for computers with low configuration and old hardware.

2. If the configuration meets the requirements, Windows 8. 1 is recommended. Microsoft specially optimized the startup speed of Windows 8. With UEFI, even the mechanical hard disk can control the startup speed within 15 seconds.

3. Set the motherboard to UEFI to boot the system that needs charging. UEFI avoids complicated startup such as traditional BIOS self-check and greatly improves the startup speed.

If the memory is larger than 4G, it is recommended to choose a 64-bit operating system from the perspective of making full use of resources.

Fourth, upgrade hardware.

1. Replace SSD and install the system in SSD. Because the reading and writing speed of solid-state hard disk is several times that of mechanical hard disk, after replacing solid-state hard disk, the startup speed of computer will have a qualitative leap. Windows 8 UEFI uses SSD, which usually takes 3-5 seconds to complete.

2. replace a higher-order CPU. CPU is the core of computer. Replacing CPU can improve the computing power of computer, and upgrading CPU can shorten the boot time of computer to some extent.

3. Add a memory stick. Memory is the computer's cache memory. If memory is tight, adding a memory stick will help shorten the startup time.

Verb (abbreviation for verb) Troubleshooting of software and hardware

1. The failure of computer software or hardware may seriously affect the performance of computer startup. Troubleshooting computer faults is generally a method of first soft and then hard.

To completely eliminate the cause of software, you can choose a recharge system. The main reasons for slow startup of software are:

① Abnormal shutdown causes file damage in the system or other application software. In general, you can find relevant information from the system log. Enter eventvwr.msc at the beginning of execution to enter the event viewer.

② There is a bug in the driver or other software or the system is incompatible. In general, you can find relevant information from the system log.

③ Disk error scanning or system update, please wait until it is completed, and it won't appear again next time.

2. The problem of slow startup after recharging with the original system still exists, which is probably caused by hardware failure. Hardware failures that lead to slow startup mainly include:

① Hard disk failure, such as bad tracks. The specific performance is that BISO can't identify the hardware implementation state by self-checking or the hard disk light keeps on without flashing after self-checking and slowly displays the motherboard brand information. The computer starts very slowly or cannot start. High failure probability.

(2) keyboard, mouse and other input and output equipment failure. Mainly manifested as slow self-inspection, slow start-up, input and output equipment failure. High failure probability.

③ The network card, network cable and network are abnormal or damaged. The main performance is that the network cable is normal and the network cable is very slow. High failure probability.

④ Other hardware failures, such as memory, graphics card, CPU and motherboard. Low failure probability.
