Every now and then, my computer screen will turn blue with white horizontal lines. I thought the original reason was my overclocked GPU (300 MHz oc'd). However, when playing games (mostly BF3) and when testing through few loops of Heaven Unigine, this doesn't happen. However, it has happened twice when browsing the internet. Once using stumbleupon with a few tabs open, and another time using facebook.
As you know these tasks require little to no graphics power, so what could be the reason this is happening? It has only happened twice, but I want to get this fixed asap.
The computer was built less than two weeks ago and have not downloaded anything that would be unsafe for the computer. So unless a virus miraculously was downloaded through game downloads/7-zip, chrome, game booster, or vlc, I don't think a virus is the problem.
The problem is my entire computer changes to this blue screen with horizontal white lines in it, however I could still hear sound coming out of the speakers, so it seemed to purely be a display problem.
EDIT: I did a fresh install, and the problem still persists. It happened once when updating the WEI and once when just browsing the internet. During games (Mass Effect 2 is the only one I've tried on the fresh install) this doesn't happen.
