I'm not suggesting it's the PSU.
If it was PSU related, you could just load up a GPU or CPU stress test and it should shut down.
I'm suggesting a power problem on the motherboard.
That would account for the randomness on the boot up and the dropping on your nic after in windows.
You said it was becoming more frequent over time. It will only get worse.
Oh I see, crap. This is not good at all. I suspected the same, but as ED said below, I posted in the PSU section so I can rule out my PSU.
I looked through my Event Viewer, and I didn't see anything that made sense. The Hardware section was completely empty as well.
I had a Kernel crash of sorts, but I don't see this type of error when I have those odd startups I described. Here's the Kernel info below. This error happened when streaming some video and surfing the net, nothing unusual.
The ONLY software related error I have found is this odd one, it did not occur at a system startup. I can't seem to find an error that corresponds to these restarts unfortunately. The QueenCreek error, I have a tone of them, that much I know.
