Custom PC wont turn OFF

Hey guys, long time lurker.

I have a custom PC that runs beautifully! Fast and cheap, running Vista. But I have one odd problem with it. When I go to shut down the PC (either by start -> shut down, putting it to sleep, or by the power button) it never fully shuts off. Instead it seems to restart and goes through boot up like i had just turned it back on or hit restart instead.

Here is a list of hardware (from memory since I am not home):

Motherboard: Gigabyte GA-M61SME-S2
Processor: AMD Athlon X2 5000+
RAM: <unknown manufacturer and model ATM> 2x2GB
HD: Western Digital 320GB
PSU: Thermaltake TR2 430W Watt ATX


Like I said, when booted the PC has no problems what so ever and runs with ease. I have built 3 PCs in the past so I do know what I am doing when it comes to the hardware, software, and BIOS. Any ideas?

  1. did you try unplugging it?


    Sorry, i couldn't resist. Could be a bad case? Im guessing that if there is a short in the power button, it could be causing it to turn on no matter what. Im gonna have to do some research on this, and hopefully someone has this problem. I have to say though, we usually answer questions on why they wont turn ON, not OFF.
  2. Ah, ive had this before, what i did to resolve this, go into bios and change it from auto rebooting on power failure :)

    hahaha yeah the only way to turn it off is to actually cut power to the PSU. As for a short in the case, wouldnt that cause the PC to short out and turn off, instead of never turning off?

    I recently built a new rig and the same thing happened to me. The issue turned out to be that my power button/restart button were wired into the motherboard incorrectly (the diagram and labeling on the pins was kind of vague).

    I would look at that before anything else.

    Interesting, I don't remember seeing that as an option in the BIOS, HOWEVER I admit that I was very tired and frustrated at the time so I will look at that when I return home. Thanks for the suggestion

    Well I explored the BIOS and no such option was available. Any other suggestions? I'll also look to see if I have the most up to date BIOS
  7. SOLVED!

    Looks like it was the case. Must have been a faulty/dirty on/off switch. New case fixed it right up. It now will shut down and sleep correctly.

    Thanks for all of your suggestions and help guys!
