system reboots after user change

Running the latest build and all hotfixes.
Tonight I set up a new Account and logon for my partner, but on switching, the system reboots. No Blue screen, no error messages, just straight to a hot reboot.
Anybody else seen this, or know of any fixes? No problems with any device drivers.
Thanks
Andrew.

"Switch User" or "Log Off"?

Well, ALL Actually.
Logged my partner into the system, just tried to make a few changes, desktop etc, and instant reset.
Did a cold start, logged myself in, same thing happened again, but no changes made to my profile.
This has been the first problem that I've encountered since my rebuild.
Thanks all
Andrew.

We have the same problem. RC1 Build 5600. "Switch User" and "Log Off" cause the computer to restart. As you said, no blue screen, no error messages, just restart. Hope someone has an answer.
