My pc is running a PIII 933 MHz processor, and over the weekend when I booted up, it gave a 'Video card failed to initialize' message, then it hung. I rebooted it and now it continues to loop through the reboot procedure, with no error message. I swapped out the video card, and that didn't work. I also swapped out the hard drive, thinking maybe the HD is bad, but that didn't work either. So now I'm stuck with a loopy computer! Could it be the BIOS or the motherboard, possibly? Help!
