Windows 8 won't shut down, please help

[Captain Carling]

I've just purchased the upgrade from windows 7 to windows 8 and it installed ok, but now its says there is a problem everytime I try to shut down, and it reboots.
I've tried unticking the fast boot in the power options but it still doesn't work.
Any advise please?

Sorted my problem, did a fresh install with windows 7 first, then the upgrade, then all my drivers etc and its worked.
Windows 8 seems ok so far
