check the fan on your video card. I had one die and the card was overheating. I got the same "visuals"

Oooooo, that's ugly. My card acts up at times. It's a Leadtech piece og shit. I'll not be buying anymore Leadtech products. My sceen totaly garbles up in a bunch of broken up horizontal lines. The fan's OK and temps are more than acceptable. It usually does it when going from welcome screen to desktop.

that happened to my gf4 ti 4600 back when it was new. fucking video cards, i hate them

Over time, I've seen that many times, and had varied fixes for it. Latest drivers or just reinstalling drivers has fixed that one time, while getting out dust in the heatsink of the vidcard fixed it another, and replacing a dying fan, with a CPU fan hanging under the card, fixed it once as well.

Thus, the three most likely culprits are chewed up video drivers, non-uptodate drivers, or card overheating from overclocking, dust in the works, or dying fan.
