Build Advice PC Does not like to be turned OFF!!!

Hey All

My PC has resently developed a probelm of where it turns it's self back on after being shut down.

When shut down and all fans and noise has stopped 3-5 secs later it starts up again!

Any ideas??? Maybe a Bios Setting????

Basic spec -

MB - ASUS P5Q-E
PSU - Be Quiet - Dark Power Pro 650
CPU - Q9400

Cheers. ~Dave.

 

check that wake on lan has not been enabled - will wake the pc up at the sign of any lan activity

 

Hey

I think the setting you are referring to is the - Lan Boot Rom - which is Disabled.

 

Have you tryed updating the bios?

Also worth checking if the power and reset buttons are causing the problem, that way you can tell if its a hardware or software problem.

Check all the power connections and front port connectors, I had an issue with my previous pc which was similar where if I moved it slightly when it was turned off it would occasionally turn itself back on, the 24pin atx plug was loose.

 

reset the cmos.. wonder if it could be a short too- take off the power button lead from the jumper when shutting down.. eliminate that too

 

I've had the same issue with a P5W DH Deluxe, I fixed it by resetting the BIOS. I'm still not sure what actually causes the issue.

Hope it helps.

 

I've also had this on 2 different systems. On one was the BIOS battery needed replacing and the other was a faulty PSU.
