Hi,
I have a problem with sporadic video corruption that seems to happen randomly. The nature of the corruption is that the screen seeme to be enlarged many times and only the top left corner is shown on my monitor. The mouse pointer is still rendered correctly(same size) but the on-screen position doesn't correspond to the rest of the screen. I tried to take a screenshot of it with Print Screen but I got the full 1600x1200 screen instead.

I'm able to get out of the corruption by bringing up task manager(Ctrl-Alt-Del) and switching user(back to the same user of course) and I don't lose anything this way, but it's kinda annoying that this can happen everyday.

My system is a Newcastle 3200+, Chaintech NVF3-250, 2x512 Kingmax PC4000, XFX GF6800GT AGP. Does anyone know what could be causing this problem?
