New Build - Windows 8.1 System Restarts Right After Shut Down

I've searched for days, including reading threads on these forums about the same problem, and have not found a solution.

I made a new build reusing most of my components: Gigabyte 970A-DS3 board, 16GB Corsair DDR III Ram, Radeon 5700 video card, Thermaltake Smaet M820W power supply, hard drives, etc. I swapped these components into a new Cooler Master Silencio 652S case with liquid cooling and a new AMD FX-8370E CPU. The system is not overclocked, it's used for work and photography, not gaming. I've got five external drives connected (two USB 2, three USB 3) all with their own power supplies, two printers, a USB mouse, wireless keyboard, external USB CD/DVD drive, internal SATA CD/DVD drive. I have two 5-port USB 3.0 cards installed.

I did a fresh install of Windows 8.1 Pro and all is running very smoothly except for this maddening problem: the system will not sleep or shut down. Immediately after putting the system to sleep, it wakes up. Immediately after shut down, it restarts. It does do a full shutdown before restarting, the system isn't crashing. Lastwake reports nothing waking the system. I've tried everything, nothing is set in BIOS or Device Manager to wake the system (LAN, mouse, keyboard, etc.). I've left the Home Group, "Turn on Fast Startup" is disabled. I've done everything I could find info for and nothing has solved this problem. The system I had these components in had Windows 8 on it and it was upgraded to Windows 8.1. I didn't have to disable anything in that system like I've tried with the new build. Sleep and shut down worked fine.

Any suggestions are appreciated, thanks for taking the time to read this.
 
Is the power switch plugged in correctly to the mobo?

Thanks for the response, and a quick one at that. This was one of the initial thoughts I had as to what the problem is. There is no positive or negative indications on the lead wired from the case. I reversed the wires on the mobo from the initial setup and the problem still exists.
 
do you have wake on _____ options turned on in the bios?

All the options are turned off in the BIOS. I also have disabled devices to wake the computer in the power management settings in Device Manager. One thing I didn't mention in my original post is that I have all the latest drivers installed and there are no conflicts in Device Manager.
 
Check for USB device wake up settings?

Unplug everything that is not necessary for the computer to boot up into windows.
 
Do you have latest BIOS. Did you have different CPU in that mobo before? I know that some intel boards have CPU specific BIOS, so reflash was needed when CPU was changed.

I have the latest mobo BIOS. I had a different AMD processor in it before.

This is a good road to go down, I'll give this a try when I get home from the office this evening. I've got a lot of USB devices so it will be a slow troubleshooting process as I'll attach them one-at-a-time and see if the system shuts down and stays down. If everything is unplugged and I still have the issue, oh well...

Thanks again for responding in this thread.

Thanks again for responding in this thread.

Before leaving for the office, I decided to start unplugging one thing at-a-time. I started with the USB receiver for my wireless keyboard which us plugged into the top panel of the case. The system wouldn't sleep but it did shut down. I'm getting somewhere.
 
I've had this issue too. First is to make you have all the latest Windows updates.

I've got all the latest drivers but this is continuing to confound me. I made some headway when I disconnected the wireless keyboard receiver from the top USB port on the case and the system shut down and did not reboot. Other times, that did not solve the problem. My system will not sleep but the monitor goes into suspense and will not come back on (even though the system is on, not sleeping) unless I reboot. To make matters worse, after one of those reboots, the case speaker let out continual short beeps. My BIOS somehow became corrupted. The motherboard has dual BIOS so it did reboot. It's strange.
 
Continuous short beep :Power supply unit failed

Assuming you have the Award BIOS version.

There's a V3.0 with an AMI BIOS.

Thanks for the response. I do have ver. 3 of the board with an AMI BIOS. It's possible that I was getting 9 continuous short beeps which would be a graphic card error. I have a Radeon 5700 Series HD card. I did get a "System thread exception not handled" error once and that is generally a video driver issue. I have the latest video driver installed and have since I got the system up and running.
 
I've made some real headway in resolving this.

I disconnected every peripheral except the USB mouse and the USB receiver for the wireless keyboard. I decided to do another clean install of Windows 8.1. After the install was complete, I put the computer to sleep and it woke right back up. I tried to shut it down and it immediately rebooted. I turned the power supply off and decided to remove the two U-Tech 5-port USB 3.0 cards I was using - these were the only cards in the system other than my Radeon 5700 video card. That worked - the system sleeps and shuts down fine with all the "default" Windows settings. I didn't disable any devices from waking the computer. I then took one card and put it into each of the three available slots without connecting the power supply to it and the problem reappeared. I did the same thing in each slot with the power supply connected to it, same problem. In the event that particular card was bad, I took the other identical one and repeated the same processes. The problem reappeared. Either the cards are the problem or the drivers which are the only ones available and are compatible with Windows 8. These cards worked fine on the older build on the same motherboard, the only difference now is the processor so it's a bit of mystery as to why they are a problem now.

One wrinkle is that the main BIOS on the board got corrupted. Since the system wasn't shutting down on its own, i would have to shut the power supply off and I imagine that this caused the BIOS corruption. The motherboard has dual BIOS so it was able to boot with no problem and I restored the corrupted BIOS which is the latest version. I don't believe that the motherboard is bad, I think it's either the two cards or their drivers. I can live with that and just replace the cards. Thanks for reading and for all the responses.
 
My issue turned out to be the two USB 3 PCI cards I was using. I removed the cards and my system works flawlessly. I have now installed an Orico USB 3 PCI card that uses a Via chipset and the system works perfectly with this card installed. Again, thanks to all who read and to those who responded to this thread.
