I know that there are countless threads already on this, but even after trying all those suggestions I still can't seem to resolve the issue.
I was installing BitDefender and had to restart the computer. The computer would boot up and seem to be loading Windows, but then it just goes blank, and the keyboard and the mouse don't seem to be getting power either.
I've tried booting into the last good known configuration and that does the same thing as above.
Booting into Safe Mode gives me the BSOD:
STOP: c000021a (Fatal System Error)
The Windows Logon Process System process terminated unexpectedly with a status of 0xc00000139 (0x0000000 0x00000000). The system has been shut down.
I've tried to repair Windows XP..but the computer won't boot from the CD..and I've checked the BIOS and that all seems to be fine It's setup to book from CD-ROM first, but it's not..
I don't know what else to do and would appreciate any help I could get.
