Various Stop Codes when booting up

The good news is that the problems do not appear outside of booting or sleep hibernation. The laptop is on and active, no issues. But I am worried that this might presage something truly bad coming in. I'd like hassle-free booting and not having to reboot when I close the laptop, anyway.

This has been going on for several months, actually; variously my hoping the auto-repair would resolve the issue and not sure when I could bring the laptop in for checking until recently. When I try to boot up, I'll often get anywhere from one to three different stop codes--not always the same ones, as you'll see--before it finally boots properly (often from the Restart/Advanced Settings screen). Meanwhile, if it ever sleeps or hibernates, it won't wake up unless I do a hard restart. A little over a week ago, I finally brought it in to a repair shop, and the situation seemed to be software-related; for some reason, the laptop insisted on starting up a small swarm of programs each time, and that was obstructing boot/waking. He adjusted settings on my computer so sleep would not be (and currently isn't so long as I don't actually close the laptop) an issue. For a few days, all seemed well. Then the stop codes came back, gradually reaching their old density. Here's what I've gone through so far:

--3/2: KMode Exception Not Handled

--3/3: Hypervisor Error twice in a row (quite a trick when I don't have virtual anything on here!)

IRQL Not Less or Equal

--3/5: Had to do a hard reset when it wouldn't leave hibernation

--3/6: First boot got stuck on a black screen, although I could tell it was receiving power; had to hard reset

Would not wake from closing without a hard reset

Clock Watchdog Timeout that froze at 0% reporting and needed another hard reset

--3/8: Same first boot issue as on 3/6, likewise the Watchdog frozen at 0%

Interrupt Exception Not Handled

--3/9: Hypervisor Error; when it self-reset, it froze at the Asus logo screen

Came to the blue Restart screen, tried that option without first going to Advanced Settings (Advanced Options?), but got the 0% Watchdog freeze

Hypervisor Error, same logo freeze

Hypervisor Error

I feel like all those stop codes have some overlap point for what can cause them, but I don't know what it would be.

Not sure what error logs I should supply. I got into Event Viewer just fine; the issue is what to paste, or whether there's a way to bundle everything as a single text file.
