After a few months of a perfectly running system I now receive an error message stating a missing or corrupt windows\system32\config\system. I'm trying to repair windows using the windows installation CD, I can gain access to the main menu by pressing the F8 key, however, as soon as I try anyone of the several options listed I always end up with a Blue Screen of Death stating Bad Pool Caller. I've tried to run the recovery console, changed memory, run memtest all passed and OK but I still get the BSOD. With these two errors i'm unsure what action to take. I'd prefer not to do a clean install (not sure if this would even resolve the problem) as i've valuable data I need to recover.
The system is self built
DFI LANPARTY nF4 SLI-DR latest Bios
Creative Sound Blaster x-fi soundcard
4 x 512GB
Technical information I get from the BSOD is:
(0x00000043, 0xc2a68000, 0x0000000, 0x0000000)
Thanks in advance for ANY HELP
