Well, the problem usually happens when I try to open a movie (.wma, .avi, whatever) or even browse a folder with movies.
The symptoms are pixelated screen (reminds a TV, or like having the screen set to 400x300 resolution), only a part of the upper-left "view" fits into the screen and there's no way to fix it without restarting.
If I ctrl+alt+del all the windows, it won't help.
If I press the power button, it slowly closes all the windows and THEN it's fixed, but it doesn't help because the PC turns off in a few seconds...
PC specs:
AMD 64bit 939 3200+ Venice
Leadtek WinFast GeForce 6800GT 256DDR
Asus A8N-SLI mother board
512x2 some DDR 3200/400Mhz RAM
Some 200GB SATA-II HDD
Please help, it's DRIVING ME NUTS YARR.
