reboots at windows screen at one house but not other

[Tim Travis]

My sister's computer gave a low hard drive space message while windows update was downloading something (not sure which). The computer rebooted and gets to the windows screen with the moving blue bar (windows XP home) and then reboots. It never got into windows.

Brought it over to my house, added an old hard drive to get more space and then started computer. It took a long time but it booted fine into windows. It boots fine every time when it is at my house. Fans are working and the computer is not overheating, I let it sit at the hardware monitoring page in the bios for a long time.

I thought it was fine, gave back to sister. She gets it home and it reboots at same place every time. Never gets into windows at her house.

I had her take computer off of power strip, and plugged into wall. nothing. Got new power strip, nothing. Nothing but mouse keyboard and monitor plugged in and she brought the mouse and keyboard with her when it was here.

So everything is same at both places except the power from the wall and the monitor. I am stumped.

Any suggestions?

Ambient room temps?

Try swapping out the monitor.
An electrical problem wouldn't act up at the same point each time.

Took my monitor to sisters apartment, still rebooted. Also moved computer to other end of apartment just to check out the fuse in her room, still rebooted.

Any other suggestions? It sounds like a hard drive problem. Maybe I just got lucky that it booted at my house.

I did notice that when I tried all of the safe mode options, it loaded files up till the agp440.sys file then rebooted every time. Could this be a video card driver or hardware issue?
