Graphics Card Overheating

[Amunet]

At least I think it is.
Sometimes when I'm playing WoW, all of a sudden, the screen will come up with a "no signal" message, and will sometimes restart on it's own, or won't let me do anything until I reset it.
Should I just open the comp tower up and point a fan at it all the time? Guess that would be the only way to make sure it's not overheating right?

i would try that as if you open then hard drive and keep it cool it may stop it then it will narrow your search down

One thing to check is dust blocking the gc fan. I had some excessive buildup between the intake/gc processor. My card was running at 111c, after the cleaning it now runs at 59c. You need to unscrew the metal plate/logo to check. (depends on the card)
