Suddenly can no longer boot up

Hello,

Here is my current issue. I've done a lot of searching and I think it's kind of a weird one:

I'm running windows 10
My PSU is a Corsair RM650
My motherboard is a gigabyte GA-Z170XP-SLI
My processor is a first gen i7 skylake
All components were high end circa NOV 2015

I built my current machine about two years ago and have had no issues with it. The couple of strange things that would happen:

  • Windows would sleep, then wake up, the sleep, then wake up.
    Sometimes on wake up, I'd get a blue screen of their horizontal bars. If I left it go to sleep again, bars would be gone.

So I was working on my machine today when I decided I should try to both update windows and update my video card driver. While in mid update, my video card driver install crashed and froze my system. I rebooted and tried it again. This time it got about half way through and then I received a BSOD. I've never received one of these on this system. Windows said it would reboot after collecting info, but the reboot never happened.

I hard-rebooted and shortly there after received another BSOD, but a different error this time.

I rebooted a third time and received yet another BSOD.

Then I rebooted again and now the computer wouldn't stay on for more than a few seconds before it turns off, waits a second, and turns back on. It does this indefinitely. In this state I can't even get to bios more often than not. I was able to get to bios once, but the system still hard froze. The whole thing seemed to escalate from bad to worse over the course of about 15 minutes.

When I did get into bios, CPU temps were around 40c before it hard froze again

Here's what I've already tried:

  • GPU is out. Just using onboard video. Still turns on and off / freezes.
    Ram is out.
    Reseated all connections.
    Reseated CPU.
    Everything is unplugged but the monitor.
    Inspected motherboard - no bloated components.
    Disconnected HDs.

I'm guessing It's a bad CPU, PSU or MB.

Any ideas? And thank you for taking the time :)

Update:

Paper clip test on power supply seems to work just fine. When the paper clip is inserted and the PSU is connected to the remainder of the components, the PSU stays on without interruption.

I also cleared the CMOS. Still continues to power on and then power off / repeat.

Also - noticed that when the system was staying on long enough to freeze that the PSU would also stay on as well. However, the system never gets to the bios any longer, even with nearly everything removed aside from the CPU / MB / PSU
