On an XP Pro PC I am getting a blue screen with stop code 7B. I have run the HDD manufacturer's (WDC) extended diagnostic with no fault found. I have put a diagnostic card in the mobo that reports no significant faults (just a problem with APM getting power status). It has exercised the disk at length but not reported any fault. I have replaced the SATA cable and moved the drive to a different SATA port.
I booted off the installation CD and ran an in-place repair. It gets all the way to Installing Windows - Installing Devices where, when two thirds through, it boots itself and restarts the Installing Windows phase.
Is there hope ?
