computer restarting instead of shutting down?

[wez130]

When i go to shut PC down, instead of shutting down it restarts, any idea why?

I turned off 'automatic restart' in startup and recovery as google suggested but it's not stopped it.

i've had this too, and for some reason the last two weeks it's stopped.

I used to have to wait to make sure it did actually shut down

what setup are you using?

I use an Asus P5Q pro with Q6600, psu is a thermaltake TR2 500w. It never did it till i reinstalled vista the other day.
