Windows 7 will not start: BSOD 0x7e
Hi.
I'm trying to fix a Toshiba laptop running Windows 7 Home Premium 32bit.
Windows begins to load with the animated logo on the screen, then it blue screens with an 0x7e error.
The info does not list a file, just these parameters:
(0xC0000006, 0x878ED630, 0X8DD1F770, 0x8DD1F350)
So far I've tried the following:
- Boot to Safe Mode - same BSOD
- Use Windows 7 disk to repair startup problems - It completed stating that Windows could not repair problem
- Tried several restore points in System Restore but they all failed
- Run chkdsk /r
- Run memory test - pass
- Remove each of the two memory modules and tried one at a time
- Removed HDD and attached it to another pc. Ran Microsoft Security Essential scan and found several infections. The most severe was Trojan:dOS/Alureon.A which took a few attempts to remove. Apparently it was infecting the MBR. After the removal, I reinstalled the drive but no change.
- I checked the minidump files, but according to the dates, it seems the current problems are being saved in a much larger file called memory.dmp. I'm not sure what to do with that one. However, there were some issues in the minidumps with a file called ccblvok.sys which sounds like a virus/malware. It has been removed.
I considered performing a repair install, but according to this forum:
You can only do a repair install from within Windows 7, you cannot do a repair install at boot or in Safe Mode.
I can't boot into Windows at all, so this doesn't appear to be an option.
So, I feel I'm at a bit of a dead end. I've backed up the Users folder, thinking the only way to fix this is by reinstalling Windows. That is, of course, unless someone can help me!
Cheers
Glenn
