Have got four machines with an identical problem. Everytime we login with an admin account the computer freezes in under a minute. Although in safe mode we can login fine. Any other standard domain users can login normally without any problems. Its only admin accounts that seem to crash the machine. Have never encountered this before and cannot find hardly any other similar problems on the net. Cannot run sfc /scannow as you have to be an admin to run that
Have tried CHKDSK from repair console also with no joy.
Hope someone can be of assistance
