Well, I'm just guessing here, but I don't think the problem is hardware-related. Until the experts come, I'll be trying to help.
So you say you opened in Safe Mode? If you did, the moniter would say
Safe in the corners of the screen. If you went in Safe Mode and this still happened, it might not be a virus, but it's best to check anyway. Do you have any anti-virus software and firewalls?
And what do you mean by "locks up"? Like, it shuts down, or does it freeze or something? And do you have the real Windows CD? If we can't solve this problem, you might need to reformat.
And what's this mean:
CANNOT GET TO DESKTOP, RECEIV
And I don't know about this:
ERR 8 - FAKE FLOPPY DRIVER NOT FOUND
Unless the name of your floppy drive is
fake...
The cavalry should be here soon, so just hold on and please turn off Caps Lock.
