Ok...so I figured out the BIOS thing with my keyboard and that works now. However, I tried starting up in safe mode and it did the same thing. It just stops on a black screen and won't advance any further. Any other ideas...thanks for all of your help so far.
It may not be the video card, if he gets a boot screen, then it could EASILY be his video drivers have become corrupted, and just needs to start into safemode, remove them, reinstall them.
