Computer Turns Itself On - Weird PC

[Micky007]

Hi,

I dont know what it is but ever since i bought this custom pc, when i shut down the computer everything is shut down except from the power or maybe the motherboard, as thats takes like an extra 5-6 seconds to turn off for some reason. But somtimes while that 5-6second wait to turn the power/mntherboard off the computer will turn itself back on again.

What is causing this to happen as i dont know if its my PSU or my Motherboard and how can i stop this from happening.

Check the bios, maybe \"Wake on LAN\" is enabled, or in the past i have had a power supply go slightly faulty and cause similar behaviour.

I had a pc do similar turned itself on and off, turned out the power switch was iffy. Not sure if you are allowed to open it up to disconnect the power switch but when i did and used a screwdriver to short the power pins out on the mobo it worked fine.

Hmmm....

Guess this is a job for the Aria Techies. Dont want to open my case and damage anything that will void my warrenty.
