Shutdown - Not shutting down ?

[Brizzles]

Any advice here ?

After clicking shutdown in Windows, windows shuts it self down - Good

But, the computer will not shutdown - i.e all system fans,pumps,lights etc. keep running - Not good

Faulty mobo ?

Cheers for any help.

What version of Windows are you running?

Vista x64 , but i'm sure its a hardware problem.
