Pc Powers Back on Few Seconds After Shutdown

[razoredraspberry]

I have been having this problem for a while. After I shutdown my system it turns back on after a few seconds and the only way to keep it off is to press the power button while the mobo splash screen is still up.

 

My Pc:

Windows 8.1 64bit

Intel 3570k

16gb Kingston Hyper X

Asrock Extreme 4-M

EVGA GTX 670 4gb

Asus PCE AC68

Corsair HX750

 

I have tried:

 

running C:>sfc/scannow in command prompt

 

Ive tried editing HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl Autoreboot to 0

 

changing power plan

 

Disabling power on after power failure in BIOS

 

Replacing CMOS Battery

Shutting down from Safe Mode

 

Shutting down through command prompt

 

Updating from Windows 8 to Windows 8.1

 

These are all potential solutions I found other places. None of them have worked. I dunno what else to do but with Wndows 10 coming out I woul dlove to have this solved before I update.

Hi I had the same problem, try installing/reinstalling drivers

I forgot to mention I had tried that in the past to no avail. Tried again after your comment and still no luck. I fear it might be a hardware issue.

Anyone else know anything else it could be? I'm sorry for bumping. I would just like a solution if there is one.

I installed the optional 8.1 updates from Windows Update and one of them did the trick I think. Tested 5 times.
