Thanks for the input Mark, but I have a question to follow up on this. Are
you saying that the video driver can cause a complete lockup of the OS? In
other words, not just the video stopping, but all other functions as well.
This seems to be the case in my situation. Actually, all I can say is that
the keyboard is frozen too, but can't say about other processes necessarily.
I have seen situations before where the console was locked up, but the OS
kept running providing, in my case, dialup RAS service. I could log onto my
computer remotely, but not at the keyboard. This was for another machine
entirely, however.

I have never seen freezes caused by bad memory. When you have bad memory you
get either failure at POST, or spontaneous reboots in windows. With modern
motherboards, overheating a CPU, will result in a automatic shutdown, not a
freeze.

With a freeze, the first thing I would suspect is the video driver, or video
card, or something related to it. Video cards, and drivers, cause freezes.
First I would try new video drivers. If that didn't help I would put a new
video card in ...any old PCI card would do. If the problem disappears then
think about a video card replacement. But if the problem is still there,
start thinking about the motherboard... maybe try more conservative BIOS
timing settings, moving PCI cards around, remove cards one at a time and see
if the problem goes away.
