My computer suddenly goes black, what should I do if my computer suddenly goes black?

Microsoft's "wog" does the weird.

My computer took the initiative to change to a black screen today.

Not bad. When the mirror Zhao also.

Turn off automatic updates.

Start-Run-Enter regedit enter, find the hkey local machine software microsoft windows nt currentversion winlogon notifywgalogon key in the left rail.

Delete the entire wgalogon.

It's all done.

Nothing to be afraid of.

Start-Run-Enter regedit enter, find the hkey local machine software microsoft windows nt currentversion winlogon notifywgalogon key in the left rail.

Delete the entire wgalogon item.

I'm sorry I can't help you, because I forgot.

Anyway, just delete one in the registry.,I'm sorry!

-Reinstall it, don't update it, or you'll use a domestic system.

Fallen into Microsoft's trap,

Is it a company computer? Maybe it's a virus.

You've patched it, but you can't do it now.

It is estimated that the memory module or graphics card is not in good contact, so unplug it and wipe it and re-plug it in.

If it still doesn't work, you need to consider whether the internal temperature of the case is too high and the BIOS settings are a problem.

Causes of black screen caused by computer host failure: You can analyze the following aspects to find the cause of the failure and take corresponding countermeasures.

1.The power supply is causing a failure. - The power supply is damaged, the quality is not good (miscellaneous), the load is overloaded (e.g. new hardware is added, the power of the graphics card is too small), Replace high-power high-quality brand power supplies (Huntkey, Great Wall, Big Buffalo, Kangshu).

2.Motherboard (CMOS parameters of the motherboard) - Memory, graphics card and other accessories are of poor quality or damaged, and are replaced by the replacement method.

3.The quality of the connection between the accessories,—— the poor contact between the power cord and the socket, the incorrect, loose, and poor contact between the memory, graphics card, etc. and the motherboard. The connection between the graphics card and the monitor, the power socket is broken, and the data cable of the hard disk and optical drive is reversed.

Memory, overclocking issues. - Transition overclocking, overclock the hardware that is not suitable for Ji Ji to kill the locusts and kill the ghosts, and restore the BIOS factory settings.

5.Poor heat dissipation - overclocking, bad fan, poor quality, high temperature system self-protection crash.

There are many reasons for this, hardware and software.

Yes, even related to the environment.

When the screen goes black.

First of all, see if the host is still working, if not, you should be able to confirm that there is a power problem.

Note: Not plugged into power.

It's the power supply in the main chassis.

If it works, then there is a chance it is.

There is a problem with the graphics card, motherboard, and other hardware.

These jobs. Take it to a professional for inspection.

All you can do is press the host power button for more than 5 seconds to shut down the computer directly.

Then turn it on again.

If you don't use it for a long time, the screen goes black again.

Send it straight for repair!

Most of them are power cords and are not plugged in. Re-check the next one.
