DG965wh instantly reboots after shutdown

I recently bought a second hand intel board that I plan on using as a server, an intel dg965wh. However I'm running into an issue, whenever I tell it to shutdown, it instantly restarts again. If I turn off the switch at the back, it will happen as soon as I turn it back on. I've checked that the bios is set to stay off on power restore. I've tried changing bios versions. I've tried replacing the psu, as well as removing the board from the case. I've disabled the LAN in bios, as well as disabling wake on lan. No matter what the problem persists. Not sure where I can take it from here, so does anyone have any ideas?

Hi Knasher,

I am sorry you are having this problem but let me help you.

Can you try taking the motherboard outside of the chassis? Clear the CMOS on the motherboard and disconnect all components from the motherboard.

Hi Kevin,

Thanks for the reply. I've already tried removing the motherboard from the case, but it didn't help. I've also reset the BIOS by restoring it to defaults in the menu, and I've also tried removing the power and the onboard battery overnight (however I'm pretty sure the BIOS settings didn't change during that). Is there another way of resetting the CMOS I'm missing out on? I'll try removing the RAM after work and see if this effects anything. I do have two DVB cards plugged into the board, but removing those didn't make a difference.

One thing I did notice is if I hold the power button down for 5 seconds after a shutdown and before it comes back on itself, then it does seem to stay powered off. This also makes it non-response to wol packets (though I can't be sure that wol is working anyway).

I know you may need the WOL feature enabled but have you tried disabling it for testing purposes?

Here you can find information about how to disable it:

I've tried disabling that, as well as disabling it in the bios. The computer will also still boot if a lan cable is disconnected. The bios setting to power on after a power failure is also disabled.

Hey Kevin,

Thanks for following up. I'm actually running linux on this, though I did have a windows install on a second hard drive in order to test these sort of things out. Anyway I've need to deploy this now so I don't actually have physical access to it any more. I was planning on having a raspberry pi set up as a server along side this anyway, so in the end I put together a simple circuit that can short the power button to ground as I need it, so I'm able to force it to turn off using this. So I guess I'll consider this thread closed unless somebody can jump in with an idea I can test out over ssh.

Thanks again.
