Explorer.exe not working, desktop black with cursor

So I've ead through the other threads about this problem but everyone seemed to be able to boot to safe mode and see thier desktop, I cannot.

Windows boots to the login screens and accepts the password but when the desktop pulls up it is just a black screen with a cursor. Here is what I've tried so far:

1. System restore to a point that was good.
2. Booting in safe mode (boots but still black screen)
3. running a new task from task manager to scan for viruses and perform chkdsk (no problems)
4. Explorer.exe will not run, even as administrator. I see it start in processes then disappears

I really really do not want to reload the OS is there any suggestions out there.

You may want to try this.

Repair Install

I would use that but can't find my disc.
