I've tried:
Virus checks (doesn't appear to be a virus)
Windows Directory Services Restore Mode
System restore
MSCONFIG, unchecking everything
Last known good configuration
Tried CHKDSK.. it says system will check in 6 seconds but when the time runs out it never checks it.
Cannot get it to load "sfc scannow" either.
Does the cd drive not work in Safe mode ? I'm trying to run the recovery disks but they aren't playing (neither is any cd in the drive).
Any ideas ?
