Windows XP Pro with GEForce AGP video card.
I've just begun to experience a "loop" of my PC rebooting over and over again - it never reaches my login screen. Does the same thing if I try to use Safe Mode. Used my original XP cd to utilize Recovery mode to attempt "chkdsk /f /r"; but, that's when I receive the blue screen with bad_pool_caller message. I'm a PC builder so I have a working system with the same motherboard (AOpen AX-533B).
Substituted RAM chip from working PC to faulty PC - wouldn't boot. Substituted AGP video card from working PC to faulty PC - wouldn't boot. Substituted hard drive from working PC to faulty PC - wouldn't boot. BUT, when I substituted both video card AND hard drive from working PC to faulty PC, the system came up and ran correctly.
I decided to leave the "working" video card in the faulty PC and used the original hard drive from the faulty PC to try a boot - wouldn't boot. So, I've decided that the driver for the video card installed on the original hard drive is corrupted. Substituted hard drive from working PC (as Master) with faulty? hard drive (as Slave) in the faulty PC and the system boots to the desktop.
Slave (faulty?) hard drive is listed as E: drive and is fully accessible. I've run chkdsk /f from the command prompt and it turned up no errors. I feel I've got to remove the video driver from the Slave drive in order to make any progress.
Am I on the right track and, if so, how do I correct this problem.
