I recently tried to run
services.msc and I noticed it had vanished from my hard drive. So I had the great idea of looking up a windows xp cd, booting from it and selecting the "repair existing windows install" option.
Everything was going just fine until I almost hit the end of the progress bar and I got a message box with the message:
"The exception unknown software exception (0xc0000409) occurred in the application at location 0x6976ea96"
After that, I hit OK, and the machine reboots, goes into setup again, gets the same exception, and so on, ad infinitum.
I tried booting with Hirens Boot CD 14.1 and running the Registry Backup & Restore Tool as suggested here, but I got an error, and I doubt it'd have worked since I only have a CCleaner .reg backup from ages ago.
I read somewhere that repair can only be done successfully if you use the exact same cd you used for installing. I'm not sure if I used the same one, and it'd be quite gruesome to look for the one I used for the install.
Any other suggestion?
- Checked my motherboard, no apparent physical damage
- Ran MemTest86+ using Hirens Boot CD. After 4 passes, no errors were found
- Ran SeaTools from a bootable CD. Both drives passed the
Long Testwithout any errors
So it doesn't seem to be a hardware problem...
