I have a Precision T1700 workstation running Windows 7 Pro we just got a week ago. I set it up for a user, installing software and configuring it with updates and network access. In all that time, I never tried to shut it down. Now I have tried to shut it down and it just reboots. I don't know if the problem was there all along or did it develop with setup.

I have viewed the System and Application logs and nothing there stands out.

I did some searching online and as a result I've disabled "Automatically restart" after a system failure. I've also gone into regedit and set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\ and set PowerdownAfterShutdown to 1 and 0. That didn't help.

The system seems to be running fine. No blue screens and log files don't indicate anything unusual either.

Hoping some Dell user out there has run into this and can shed some light on this.
