My pc won't shut down or sleep, it only restarts!

So I finished my first custom pc build recently and almost everything is running perfectly. I installed windows without any issues and the performance is really satisfactory. Here's my build:

The problem I'm having is that whenever I shut down my computer (clicking "shut down" in windows), everything turns off (the fans stop spinning, etc.). But after having shut down for a second or two, it just boots back up again with no command to do so. The same thing happens when I put it into sleep, so I have to shut it down and then quickly shut off the power supply in order to fix this issue.

What can I do to diagnose this problem? It seems really odd to me. The troubleshooting steps I've taken so far are:

1.) Install all the "unknown" device drivers listed in windows.
2.) Updated my BIOS.
3.) Checked my settings to make sure I don't have any "Wake On ___" functions enabled.

I have a suspicion that its a Windows problem because if I recall correctly, before I installed windows this issue wasn't here. I'd appreciate any advice.

  1. Right click "My Computer"
    Select "Properties"
    Go to "Hardware Device"
    Click "Device Manager"
    Select "Network Adapters"
    Select "Marvell Yukon .....PCI-Fast Ethernet Controller--> right click ---properties--->power management-->deselect "Allow the computer to turn off this device to save power"--->Go to "Advanced" tab--->put value off for "Wake from shut down" --->value none for "Wake up capabilities"
    press OK
  2. prit87, Marvell Yukon isn't an option. I'm using a different wireless adapter, but I still went to see its properties and deselected the "allow the computer to turn off this device to save power." The other options were not available to me under the advanced tab. It hasn't solved the problem :(

    THANK YOU SO MUCH I finally got it working! I didn't want to go to the trouble of removing the battery so I just manually jumped the pins to reset it.

    Thanks again!
