I hope adding my two cents helps - I am having the exact same problem as described here (I have another thread going that I started aweek ago, but am getting nowhere!) I have a Dell Dimension 4600 running Windows XP SP2. My problem started on 11/19/05 after I did a Windows Security Update. My system seemed to run fine after that update, but later in the day I went back to the machine and tried to get from the screensaver to the desktop. Thats where I got hung up. The system totally locked up. When I tried to restart the machine, I got hung up at Windows Is Starting Up.
I have tried to start in Safe Mode and have only been able to get in once (after literally dozens of tries.) When I did finally get in, I could log in to Admin, but couldn't run anything. Then the PC locked again.
One little side note - dont know if it means anything. I have five profiles set up on this machine. When I did get in to Safe Mode the one time, I was able to access the My Documents file on four of the five profiles by using the Windows Explorer (and was able to back up the data to an external HD.) The fifth profile gave me an "Access Denied" type error, even though I was logged in as Admin. Weird!!!
I ran the Windows Install from the CD and did a repair. But the system still hangs on the Windows Is Starting Up screen.
Yesterday I booted to the Utilities Partition and ran hardware tests all day. All the hardware is passing the tests.
I thought this problem was unique to me, but am seeing more and more of this EXACT complaint on G2G. Could a Windows security update have caused this???
