Hi there! I've got a weird problem and was hoping you guys could help me out.....

Board: Asus K8N-E, socket 754, nVidia chipset
Proc: Athlon 64 3000+ (clawhammer)
RAM: 1GB (2x512)
Video: ATI Radeon X1600 256MB AGP
O/S: Windows XP Home SP2, up to date

My wife and I share one computer, using two separate user accounts. She works from home, so I'm usually running a few apps before I go to work. I leave these running and she uses fast user-switching to work from her desktop all day. Lately (of course, she didn't tell me when it started to happen), when she tries to switch from my account to hers, Windows prompts for a password; BUT THERE IS NO PASSWORD ON HER ACCOUNT!!! If she tries to log back in to my account, it also prompts for a password, but my account is the same...there is no password!
I've tried using the administrator password, just hitting enter, etc, etc, but nothing will get me back to either desktop; I'm stuck on the Welcome Screen. I've googled around, and tried some solutions for similar problems, but I haven't had any luck yet; nor encountered anyone with this same problem.
So, to review.....when the comp is first started, you can click either username (there are only two, both administrators), and it will log on no problems. If you click Start, Log Off, and Switch User; you are back to the Welcome Screen, but cannot log in to either account; and you're forced to restart from the "Turn Off" button on the Welcome Screen.
I have checked that the Fast User-Switching service and Terminal Services are both started automatically, and seem to be error free. There is nothing in the logs to suggest the source of the problem. I heard of a few ppl having problems with Fast User-Switching while using ATI video, and for them a driver rollback helped, but it didn't help me.
I'm out of ideas.....so here's the word you're expecting:

I dont know if this will work or not. But l would try to start windows in safe mode and go under the administrator account. Then set up a password for both accounts that you cant get into. So that way you know the password. Then restart and see if you can get in using the new password. Let me know if this works or not. I never seen this problem before. To enter safe mode hit f5 or f8 i think while you are booting up then choose safe mode.

At times corruption of the video drivers will cause strange behavior in Fast User Switching. Try updating yours to see if it helps.
