My PC's prone to problems and its getting on my nerves. This time, I was just trying to get my pics into the PC from my iPod while browsing a website. It was a bit slow today and all of a sudden, it froze. Force shut down, start it up again and the next thing I know is that something funny's happening to my PC. Glitchy screen. Again. Even when it starts to boot up. I think its my graphics card doing this but then again, the PC's not responsive whenever I tried to exit the disk-check. So, probably some asshole just stealth installed something in the PC. What's going on?

Quick edit: oh yeah, I didn't visit a virus site that time
