Quick specs: Nvidia 7900 GT vid card, AMD dual core, Vista, and all updated drivers.
Anyways, for a few months now, my screen is having little dots all around when I am using it, and in rare cases will completely freeze up. Now, I do know it's not my monitor, as I use it for watching TV through it's component hookups and is perfect. Also, the strange thing is that on the "Welcome" screen, it ALWAYS doesn't have any dots, but on the boot up screens beforehand it does.
Is it my card overheating? I've cleaned it all up, and also don't run it very hard.
Any help would be appreciated
