Windows server 2008 SP1 keeps retstarting itself after the ctrl+alt+del screen.

I have to quickly watch the screen and login within a minute. Even if I miss a second, it restarts.

But, once I login, it stays calm.

Any suggestions?

Thanks.

Is it a graceful reboot or a sudden / blue screen style reboot? Does the same happen in safe mode? – Dan Dec 31 '12 at 11:09

Look at the logs, there's bound to be some tell-tale line in there.
