The problem...
I've had a small variety of quirks and weirdness happening.
1. The boot time being long. I didn't really think more of it originally, but it's getting on my nerves. I assumed it was a bad stick of RAM somewhere, since I purchased the 64GB of RAM in one go back in May, and that's about when I noticed the initial quirkiness.
2. I've had two, maybe three occurrences where the system plainly hung up. Looping audio, frozen screen, no reaction to input. Wouldn't go to bluescreen.
3. Booting up again after those hang-up times I'd get "Overclocking has failed!" messages from the bootscreen - where it lists my specs and stuff. The problem herein, however, is that both my CPU and RAM were already running stock clocks... I've also since had it separately once or twice when booting.
4. I started to run some diagnostics yesterday. After a few things I checked Event Viewer, and it had two regular events happening that were weird...
- First there would be this error:
Windows failed fast startup with error status 0xC00000D4.
- A few seconds after, we had:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
- This was happening once a day - and seems to match when I am booting my computer.
Notes & things I've tried...
General upgrade path...
- I upgraded to the Intel 5820k and Sabertooth X99 in August last year. It was a little slower to boot, but I concluded that was just normal X99 business.
- I got a new SSD - the Samsung 850 Evo 1TB - in February. I was building a new computer out of spare parts to sell to a coworker.
- And in April my previous R9 290X cards were sold, and I picked up an R9 380 for cheap for a hold-me-over till new stuff came out and dust settled.
- In May I purchased the RAM and installed it.
- I'd previously run custom watercooling loop. In May, around the time of my RAM upgrade, I replaced the loop with a Noctua NH-U12S.
- Just weeks ago I purchased and installed an EVGA GTX 1070 FTW - the day after installation the whole VRM cooling fiasco is revealed, yay.
Yesterday, I had some time to kill, so I decided to stop being a lazy bum about it and run some diagnostics.
- I removed one kit of 32GB RAM. Got an "Overclocking failed!" message. I kinda wrote it off as a derp because the system was short 32GB RAM compared to before, but Idk in retrospect.
- Ran a Windows Memory Diagnostics. (I should've run it on the whole bunch first, come to think of it...) No errors came up here.
- Changed "AI Tuner" from "Auto" to "XMP" - I'm a dumdum, but I honestly don't know if this did anything to or from.
- Booted up this morning. The error combo from before (Failed fast startup and unexpected loss of power) came up as happening during boot when I checked Event Viewer.
Plans for things to try today...
- My current plan is to test the other 32GB kit in Windows Memory Diagnostics.
- If nothing comes up I want to check Event Viewer for any new occurrences of the error from before.
- I should confirm whether or not I have fast boot enabled. I don't remember, honestly.
- Maybe I should try my old 16GB DDR4 kit from Corsair. I never really had noticeable problems with that that I recall.
- Update UEFI - there's certainly a new one somewhere
Aaaaaaaaaanyway, that's a lot of shit up there. Mostly, I'm posting this here to ask if anyone has any further ideas of how to diagnose this and figure out the root cause.
