Alright for the last month or so i've been having this problem. First I thought it was a driver thing. I started getting Red, Yellow, Blue, etc stripes across my screen. First reinstalling drivers would fix the problem but it kept comming back more frequently. So I assumed my card was shot. I noticed the fan wasn't spinning at all so i downclocked it. This helped for about a day. The stripes returned just as bad. So i had my processor a little overclocked and thought maybe this was the problem. Turned this down alot and it helped for a few hours. The stripes are here and my computer is crippled. I'm assuming this is a heat issue. I'm going to try and get my hands on some compressed air and clean out the case. Here is a picture: link
