So... I'm using a Leadtek WinFast A400 GT which is a GeForce 6800 GT 256mb card... and I've been using it for over a year just fine. In the passed couple days it seems to be overheating. I would be playing World of Warcraft like usual and the screen would turn all crazy colors of lines vertical and horizontal and my computer would restart. This happens everytime i play World of Warcraft now. I opened the case up to find the video card incredibly hot. Hot enough to burn my finger if I left it on the card. I tried running it with the case open but it doesn't seem to help. I also installed the newest drivers and that's not helping either. Any suggestions would be great. Thanks. If you have any questions just reply to this thread.
