Question

Sometimes while i am working on my PC everything stops and the screen goes off but the PC still working but everything comes to a complete halt.

It is slow too.

and it doesn't run a deskcheck when it doesn't shut down properly.

I have changed all the software and some components of the hardware too. but these three problems

Can anyone tell me what causes this.

Answer 1

if only the screen goes off this can be a problem at your computer monitor.

Try to check if all cables are well connected on the monitor and at the computer as well. if possible try to do a test using other monitor and check if the same problem happens. If it happens then the problem can be your graphic card otherwise it is indeed your monitor so you can try to fix it or buy a new one.
