My 9500/120 (Sonnet G3/400 96/1Gig, 32mb Video card, asante ethernet card, usb card, adaptec u2w/9gig [works, but waiting for software to recover HD]) I think that takes care of the specifics. Anyway, sometimes the thing just turns off, no warning, no usual precursers. Sometimes after running for hours. Then restarting is like starting a sick car, but eventually it will run. Power supply, or what? You've helped a lot with my questions already, I'm sure this isn't much of a test of your skills.
