check out the fans first. especially the one on the video card. i had one system where the graphics card fan died with similar results. also try to re-seat the video card and the power connector if it has one. your idle power seems %5 lower than nominal which is not bad but you have to check the load levels too. there are some programs which show you the voltages from within windows.

If it has an Antec power supply, it's probably the power supply causing problems. You should also check the capacitors for bulging and run memtest to see if a DIMM went bad. Good luck with it!

Just a follow up to the post I am replying to. BTW, thanks to everyone who helped me. The problem turned out to be the NVidia card (7900 GTX). I got a new power supply, and nothing changed. Now, I just installed a new graphics card, and all of the artifacts I was seeing disappeared (based on what I tried so far). I haven't tried the second boot partition to Vista 64 yet. Hopefully that one is working now as well. So I don't know if the graphics card itself went bad, or if Nvidia somehow screwed up the code path in their drivers that controls the 7xxx generation cards... Joe
