Strange Problem

[DarkZero]

Unfortunately I haven't got one. I do have an old PS/2 keyboard. But even with that it's freezing up.

So far I've tried:
* System Restore
* Cleaning registry/old files/etc
* Removing all startup items
* PS/2 keyboard

And none worked...

When I turn on my computer, it never freezes at the login screen. If I plug in a keyboard for a second just to type in the password and hit enter and then unplug it. The computer will load fine but crash again after about 5 - 10 minutes.
