Suddenly Stopped Working

Hi all, i really need some help as I am now totally stumped.

Spec:

Asrock Z170 Gaming K6
i5 6600k
GTX 1070
Corsair Force SSD 500GB
1TB 2.5" HDD
Watercooled
Asus Wireless Card
2 x 8GB Corsair Vengeance DDR4

My computer was absolutely fine for months, i then turned it off and didn't use it for about 2 weeks. I turned it back on, it was fine, put it into sleep and went to turn it on the next day and the errors began.

First it was stuck in a boot loop, I disconnected everything and cleared CMOS many many times getting code 00, eventually it posted however wouldn't detect any USB device. Eventually i plugged my keyboard into one of the USB 3.1 ports and managed to boot to windows.

Now I am in windows however my USB 3.0 controller could not start (Error Code 10), tried unplugging the power for ages, tried updating drivers using the common methods i can find online - nothing. The USB ports have power but do not detect any devices, they are completely unusable.

Then i had issues shutting down, windows would shut down but then the computer would stay turned on but display either 04 or 05 on the Dr Debug - memory error. I changed the memory to 2 different slots (still in the correct configuration) and the error went away, however now the computer won't shut down. Windows shuts down, i lose the screen signal, all fans and HDD continue to run. After a while i push the power button and the windows login screen comes up immediately, almost like i've restored it from sleep.

Also, when i set the bios XMP profile to Profile 1 (what it has always ran on) I will then get stuck in a boot loop with IE showing on the Dr Debug LED.

Any ideas?

Thanks for the reply.

Sorry i missed the PSU, it is a Corsair AX 760.  I've made sure all the cables are in tight.

I have run the sfc /scannow command and it came back with no integrity violations.

Yes, the lovely windows 10. Seems horrifically broken!

I've made a video, it's not the best but i'm trying to upload it and will post the link.

PSU does sound possible, the ram not getting enough power could explain it not posting and the USB ports not getting enough power is apparently an issue in Windows 10 (I've disabled the power management for them)

It was oc'd, I cant remember what settings I had it at as it was fine for ages (I think it was at 4.5GHz), however while stress testing the temps didn't go over 60c. Currently on base clock, all fans on silent and the pump turned right down the temps are 20/21/20/19.

I see, so why would it suddenly be going into sleep states rather than shutting down? I haven't changed any settings re: sleep/shut down. It is showing 04 again now when shutting down, however restart works (shows 04 for a few seconds then reboots).

I've updated all of my other drivers, still no joy with the USB ports.

While using it (not including the USB ports) it's generally faultless, however every now and then my RAM usage is at 100% and the computer is unusable. I have to force power off, wait a few seconds then start it back up.

Not to my knowledge, however it is quite possible the other half has and not told me!

I've already reseated all cables (even fans) both board and PSU side, so looks like CPU out job which is going to be a nightmare, however windows won't boot at all now and is telling me to insert correct boot media so another problem to fix! I should have stuck with Windows 7...

I'm doing a completely fresh Win. 10 install on it now to see if that changes anything If not i'll most likey be RMA'ing the motherboard, PSU and CPU and then look at getting a different board. I can't think of any other steps i can take (I'm running it now bare bones to install Win 10)

Then reseating the CPU didn't get you anywhere concerning this issue?
