Why does my computer freeze when the screen appears after turning it on?

I want to ask you, is your computer the kind that crashes as soon as you turn it on? If so, there are two reasons, first, the motherboard northbridge chip is damaged, this problem can not be repaired, only to replace the new motherboard, second, there are bad sectors on the hard disk, when the location of the boot file is read, because there are bad sectors on the hard disk, it causes a crash. Depending on the severity of the hard disk, if it is not too serious, it can be repaired, and the maintenance fee is about 50 yuan.

I don't think it's the computer that is dead, it's possible that the desktop files are dead. You can finish the desktop file in the Task Manager and re-run it. That should fix it!

Then there is that the antivirus software does not mean that there is really no virus on your machine, if it is convenient, try the system again. If the same problem still occurs, consider whether it is a hardware problem!

It's the same with my home computer, it's a problem with the program.

Try to enter safe mode to see, if it doesn't crash, if it doesn't, it may be a software conflict.

Remove the battery and restart it.

1. Too little space left on the hard disk or too much disk fragmentation will also lead to "crash" failure, because some large applications need a lot of memory when running, if the physical memory is insufficient, you need to use the virtual memory on the hard disk, at this time, if the remaining space of the hard disk is too small, then it may cause the phenomenon of dead thoughts.

2. The possible reasons are: antivirus software is installed more, and all the monitoring is turned on, less monitoring is opened or not open the monitoring, and the virus is often checked and killed. If the software or driver is not compatible with the system, reinstall or upgrade the driver.

3. An important cause of the crash is the intrusion of the virus program. As we all know, a virus program is a malicious attack program that will damage the computer software system and occupy a lot of system resources, and it will cause great damage to the software of the computer itself.

4. The main reasons why the computer crashes after a while after booting up are: poor heat dissipation; Excessive dust in the machine; Poor contact, etc. Secondly, it often happens that the computer crashes directly after booting or automatically restarts for no reason, the main reason is that the CPU temperature or other parts of the computer are too high.

5. Will the computer crash if it is left on for a period of time? There can be a variety of reasons for this, here are some of the possibilities: Computer overheating:

When the computer is running, if the CPU or graphics card is overused, a lot of heat will be generated, and if the computer is not cooled well, the temperature is too high, and it may crash.

6. There are several reasons for the unstable use of the computer: dust causes the system to crash: dust is the enemy of the computer.

Excessive dust adhering to the surface of CPUs, chips, and fans can lead to poor heat dissipation of these components, and dust on circuit printed boards often leads to short circuits in humid environments. Both of the above scenarios will cause a crash.
