Logging off user problem, Please help

I have two users A and B. I am logging on user A. I used to switch to user
B.So far, so good. The problems start when I decide to go back to userA
either using logging off B or switching to user A. I came upon to a black
screen (the power is on) and nothing is done.
From the XP discussion groups I discovered UPHClean, I 've installed it and
the problem has been fixed temporarily. Rerun it and for the time being my
system can switch back to user A from user B but not logging off user B and
return back to user A. Again the beautiful black screen...
I'd appreciate your help.

I realize you asked this way back in July, but I just had my hard drive and
operating system replaced and the same thing is happening to me.

Did you ever get this resolved? If so, how. Thanks!
