One of our laptops is running Windows 7 Professional (upgraded from the Home edition using the Windows Anytime upgrade). It is the 64 bit version.
Today upon booting the machine something strange happens - it boots to the logon screen (Press CTRL + ALT + DELETE to log on). It then asks for the password, however it then reboots after around 15 seconds. If you enter a password befor the 15 seconds have elapsed, it won't let you enter it (the characters appear in the box, but pressing Enter or clicking on the arrow does nothing).
It works in Safe Mode - any ideas how to resolve this?
