Start-run, enter "cmd" and press enter at the command prompt and enter: For % 1 in (% WINDIR % \ system32 \*. DLL) Do regsvr32.exe/S % 1 if you are afraid of incorrect input, you can copy this command and click C: in the upper-left corner of the command prompt box. Right-click and paste the command to avoid errors. Press enter and wait for 1-2 minutes. After the rapid screen rolling is completely static, wait until the hard drive lights are off and restart. It may also be that a newly installed software has a problem or the patch is not fixed. Find it, uninstall it, and reinstall it. If the problem persists, it may be caused by memory incompatibility or internal quality problems. Try another memory. Or if you add a memory stick, you can solve the problem by reinstalling the system. We recommend that you use the installed system disk instead of ghost, because the ghostversion is not stable, in addition, the ghost version of the system is prone to this problem. This is the experience I have summed up after this problem!
