WTF is wrong with my sister's computer!?!?

[Gatecrasher3]

Alright so I built this rig about a year ago for my sister?s business. Its an e8400 with a asus P5K VM mobo.
About a week ago the on board video card died on it, no big dear i put in a crummy MSI NX7100GS video card I had sitting around. But now the computer just will get to the windows XP loading screen will almost get to the windows welcome screen and then it restarts itself. I got into safe mode and installed the drivers for the card but it made no difference. I also reinstalled XP (over the old one, did not format) but that also did nothing to fix the problem.
Any help please!

Start by running memtest at least 3 passes, overnight is better, if you get errors try different RAM. If it won't rum Memtest W/O crashing then PSU, Mobo, CPU Heatsink not installed properly are the next things to check. More info on all your components would also make it easier to help, like PSU model, RAM, any other accessories etc.

look in the BIOS, should see an option to disable the onboard graphics chip.

The odds of onboard video dying without the motherboard failing as well are usually pretty slim. Sounds to me like the board is dying as well.
