Thanks for the info. I had him do that so he's definitely in the right place now. But the computer restarts soon afterwards (during the setup stage after having selected repair).

Any ideas? He's pulled memory one dimm at a time just in case it was some bad ram. Settings in BIOS are pretty much standard (nothing changed recently). He thinks he may have uninstalled some application prior to this whole issue cropping up, but he's not positive the problem occured immediately after that (ie. the next day when he restarted for instance).
