I have recently built a new computer after having multiple issues and problems with my last one. However, this one does not seem to be without its own problems now. Whenever I play games (Magicka, World of Warcraft, Assassins Creed, SimCity, Starcraft 2, pretty much any game), either the graphics driver
fails, shutting off the display for 5-10 seconds before restarting, or the computer flat out locks up. The screen freezes, sound plays as normal for 5-10 seconds before the sound locks up as well giving the long grating sound before everything falling silent. At this point it will stay like this until I hold down the power button. If it helps at all, after I press the power button again to turn it back on right after there is a several second delay. Read somewhere that it might be a power supply issue. Any thoughts/help/advice?
