Windows 7: Screen going black

hello.
first of all i don't know if this is the right section to post this if it isnt then im sorry
but my screen keeps going black at random i dont know if its some driver thats corrupted or if its some hardware thats going bad any suggestions?

hi Kriller, and welcome to sevenforums,

how random is it? do you have to reboot to get it back?

do you have another computer to test the monitor with?

1st - Reinstall your drivers.
2nd - Check all the cables are connected properly. You'd be surprised by the amount of problems caused by loose cables. Try using a different cable, too.
3rd - Try moving the graphics card to another port.

If all these fail, and the monitor works without the black outs, you need to get a new graphics card. If the monitor black outs on another computer, and the cable is fine and everything, then you need to get a new monitor.

@mickey yeah i used to be able to just reboot and the problem would be gone but now if i scroll up or down in some internet browser too fast or if i change windows alot it starts again
@NoaHall oki il try with the 2nd and 3rd options cus ive already done the 1st one :P

Oh, on further details, it could also be a RAM /power to GPU problem.
Make sure all internal connections for the GPU are correctly connected, your PSU should be powerful enough for it, unless you've gone with a cheap brand for it.

In order to check the RAM, use Memtest86+ - Advanced Memory Diagnostic Tool and let it run for a couple of hours.

oki il try but im really not good with computers but thank you

It certainly sounds more like a problem with the graphics card than anything else, in my view.

oki i should get a new card then and hand over my computer to someone who can put it in cus i really dont wanna go pokeing around inside the box xD
