Power On / Wake Crash

I recently upgraded from windows 8.1 pro to 10 pro using the media tool. I've run in to some issues here and there, fixed some, but one i cannot figure out involves the system powering on after a crash.

Usually when i am not using my rig i put it in hibernate(which i had to add to the start menu in 10). for the first day or so this was not an issue. however now when i wake it, this is what happens. My mobo splash shows, and the black windows 10 load screen with the windows logo shows up, but before the spinning dots start, the system just powers down. i hit the power button, and it will load properly, though snail slow compared to 8.

Thing is, it always does this on first boot. It doesn't matter if I am waking from hibernate, or sleep, or had actually shut down and am booting cold. but it will always start after that, so far at least.

It also takes quite awhile to boot. with 8 i could wake from hibernate in a matter of seconds, maybe 30 seconds from cold boot. its much slower than that now, often sitting at black screens between the windows load and green load, or the green load and login, or login and desktop. I am uncertain if the slow load is related to the boot crash.
