These graphical artifacts pop up randomly while I'm using my computer. It just started happening a few days ago. Sometimes the screen will turn completely white and I'll be forced to restart my computer manually, as it becomes unresponsive. I've reinstalled my drivers, cleaned the dust from my case, and ran tests with another monitor (problem still occurred, so it's gotta be something else right?). I really don't want to have to spring for a new video card, so if anyone technically inclined could help me out here, I'd appreciate it. Will post specs if needed, just lemme know what you want.
