So I was playing WoW on my 2 week old computer. and the screen went white with colored lines. I could still hear everyone on vent and apparently move around in WoW. I'm not sure if its the graphics card (which it shouldn't be) or the monitor which is old. When I hit the menu button on the screen the menu doesnt come up. When i plug and unplug it from the comptuer the white lines appear and reappear but i think thats just the monitor going to sleep or whatever. i dont have another monitor or the cord to try it on my roommates laptop.
