while playing a game my screen went whacko! it was all scrambled an unreadable. I restarted my pc then everything was fine...for about an hour. then it got all scrambled again so I rebooted. Now I can not get it to come on at all!..Monitor is just blank. I have an acer aspire m1100. windows vista. Can anybody tell me what is wrong?
Thanks in advance

Scrambled screen sounds like video card went bad. What kind of computer and what kind of video card?

THe fact that you can not get it to boot at all now seems to be a Power Supply issue rather than video card issue. A power supply going out can cause video problems as well as other seemingly unrelated problems.

is there anyway to check before buying, which one it could be?

As far as testing it. The best way is to attached a known good power supply to your system. see if it corrects the problem.
