Go into BIOS and see if there is an advanced setting to allow the system to restart after a power interruption.

What's BIOS?

OK, we may not want to go here ...

The Dell BIOS is access by hitting the F2 key (?) when you first start out, and it will let you into a special section of the computer that keeps the setting when the computer is turned off.

Normally I would just say to get professional help. Maybe a local geek to look at it.

Its probably a Windows update or a driver issue that causing the problem.

Anyone else want to take a stab at this?
