OMG It worked 3 hours ago

Wow, my computer never ceases to amaze me. I unplugged my peripherals from the back of my system to allow my friend to use my system on my monitor, keyboard, etc. He wanted to test his new build because he wasn't very good with computers. Anywho, 3 hours later he removes his system and I plug mine back in. Everything goes fine until it's about to pop-up the log-in screen when I get my friend the blue screen of death. I stopped it and I got these error messages: c000021a, 0xc0000135, 0x00000000. Does anyone know how to fix these problems or what they mean, the microsoft website offers no help because none of the problems are related even closely to mine. Any feedback would be greatly appreciated.
PS: I don't want to have to reformat the hard drive, or if I do I need a way to get all of my personal files off of it first.

We need more details from the error screen, just the numbers don't help much, there should be some verbage first.

This is exactly what the screen said:
stop: c000021a {Fatal system error}
the windows logon process system process terminated unexpectedly with a status o
f 0xc0000135 (0x00000000 0x00000000)
the system has been shut down

My recommendation is that now, since u have the info that it said, either u log onto safe mode and fix it, or what i would do is restore my setting to previous best settings(use system restore when starting in safe mode). If that does works try restoring by press f8 or whatever button when u just open the computer and choose the option, restore to best privious settings" or sumthing like that. The go on the net and look it up if you still get that BSOD when booting.

Well, I tried all of that before starting this thread, but I am fixing it, I at first tried repairinr Windows, but it was slow once I logged in, but I was lucky enough to be able to copy my personal files to a second HD. Then I just formatted and reinstalled windows, I do appreciatte the feedback though.
