The fact that it is losing power kind of tells me that your ps might be the issue. If it is bad do not run it this way as fluctuating power can trash a ssd controller.
I created an account here just to reply to this thread. OP, you are not crazy and there is nothing wrong with your build or your hardware. Me and countless other people are experiencing the same issues as you and there has yet to be a viable solution.
Here are the symptoms of this issue:
1. NVidia drivers install correctly in windows, they work, and are up to date
2. When the machine is rebooted the following occurs:
* Bios screen is displayed
* Spinning circle progress meter for loading windows is displayed
* Suddenly the keyboard and mouse flicker off and the machine is rebooted again
* The previous 3 bullets above are repeated until the second reboot displays 'Starting automatic repair'
3. At this stage the only way to restore to a working system is to go into Safe Mode and re-install the stock OEM NVidia driver
It is important to note that, in my case and most of the cases reported, IF you install the version of the NVidia driver that came with your GPU (in my case that is V344.11) then the system is stable, consistent, and reliable but IF you use any other driver version then the reported symptoms above will occur. You are essentially locked into the manufacturer nvidia driver version.
I have tested voltages and wattage, I've disable UEFI fast boot, I've enabled classic boot, and I've even rolled my GTX 970 back to my original ASUS Radeon HD 7870 OC and all produce the same results. The Gigabyte GTX970 (FW: 84.04.1F.00.FD) just cannot function with Windows 8.1 X64 with any driver other than the stock OEM driver included on the driver CD that came with the graphics card.
I've been at this now for about a week non-stop and at this point I'm convinced that there is a fault in the hardware design of this GPU. I haven't used an NVidia graphics adapter in 15+ years and this is going to be the last one I ever purchase as I've never had any issues what-so-ever with the AMD/ATI GPUs.
If you're curious here's the spec-sheet on my hardware. Note the bottom of the paste, which articulates the changes made to this build in January 2015 (notably, I replaced the ASUS Radeon HD 7870 OC with a Gigabyte GTX970 G1)
