Recently my computer has been running weird. Whenever i play my games such as Resident evil 5 and Starcraft 2 and in the middle of the game my screen just turns fucked up. the grapics are messed up, there are lines all over my computer my mouse icons are fucked, just everything looks messed up. I thought it was my video card so i upgraded it to a gtx 240 but that didn't solve anything. so i got 1gb of ram and that didn't help to. i have no more idea's of what is causing this problem, does anyone know??
