What should I do if the computer crashes and can t turn it on, and the computer crashes and can t be

1. The CPU is overloaded, or it is not working properly. Check CPU and graphics card cooling, dust removal, oiling, or replace fans.

Second, the power supply voltage is unstable and the power supply is insufficient. Replace high-quality, high-power power supplies.

3. Clean and defragment disks frequently.

1. In the "My Computer" window, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter "%temp%"-OK.

3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

7. Reduce the burden of memory, do not open too many programs. If you have too many documents open or too many programs running at the same time, you will not have enough memory to run other programs, so you should close the programs and windows you don't use at any time.

4. Upgrade the graphics card and network card driver, and change to a higher-grade graphics card.

Fifth, increase the physical memory, now the memory is generally at least 2G.

Analysis of the reasons why the computer crashes and can't be turned off:

It may be caused by system bugs, computer memory overflow, viruses, or hardware heat dissipation, poor memory contact, etc.

Workaround:

1. Directly press the switch button on the front panel of the computer host or notebook, and press and hold for 3-5 seconds to shut down the hardware. After booting the computer, check whether the new software has been installed recently, causing the incompatible system to freeze.

2. If there is no uninstall the software or misoperation, then use antivirus software to check and kill the virus, see if there is a virus, if there is a virus, it may be caused by a virus, use antivirus software or computer manager to scan.

3. If there is no virus in the computer, then check whether the hard disk space is too small. If yes, delete the unused files and defragment the disk. If the hard disk space is not small, and then check whether there is a pattern of crashes, such as the computer always crashes after running for a period of time or crashes when running other large game software, it may be caused by poor heat dissipation of CPU and other devices, open the case to check whether the CPU fan is rotating, how the wind is strong, if the wind is insufficient, replace the fan in time to improve the heat dissipation environment.

4. If the computer has good heat dissipation, then test the computer with the hardware test tool software to check whether the crash is caused by the poor quality and quality of the hardware, and replace the device if so.

Dear, hello, the computer can't be shut down if it doesn't move, and the solution is as follows: 1. You can press and hold the power button to force the shutdown, and then turn it on, press F8 continuously, enter the safe mode or configure the correct mode for the last time, if you can enter normally, the system will automatically repair the registry, if you have anti-virus software installed, you can carry out a full anti-virus investigation in the safe mode; 2. If you can not force the power button to shut down, then you can only pull out the power cord, and the operation is the same as the above steps after restarting, if you can't turn on normally, it may be a hardware or other problem, it is recommended to go to a repair shop for repair. Dear, I hope mine can help you.

What should I do if the computer crashes and I can't turn it off1, press and hold the shutdown button, don't let go. Be sure not to let go of your hand during some of the process, usually the computer will shut down after a few seconds, and then let go of your hand. 2. If you can still open the Task Manager, select Task Manager Shutdown-Close.

3. Click Start Running, enter shutdown-s and click OK, and then a forced shutdown will appear. 4. The system does not respond, which may be the reason for too many running programs. Check out Task Manager to see which runners choose to end.

5. It is best to optimize and clean up the system for the computer, sometimes it may be that there are too many junk files that affect the process. 6. Use anti-virus software to do a check-and-kill, sometimes it may also be caused by a computer virus. 7. Use the system's built-in system restore to restore to before the failure.

8. If you still can't solve the problem, you can use the system installation disc to reinstall the computer system.
