Hi, I hope one of you computer guru's can help me with a problem i'm having with my PC. What's happening is when I turn the computer off via the power switch, Vista closes and shuts down ok, the computer powers down but nine times out of ten it turns it's self back on straight away! I then have to turn the power off at the power point before it gets too far into post startup.

I have checked the BIOS setup with power on options and have disabled PME event wake up's and system after AC back to off, also removed peripheral devices thinking they might be causing it but it still happens!!! Can anyone please suggest a solution to this problem, any help would be much appreciated.
kind regards Monty
