Guys, I've been struggling with this issue for about 3 months. I have GA-Z87X-UD5H, 4x8GB Patriot memory, EVGA GTX 1080ti and I tried literally everything mentioned in other posts. Nothing helped. I was still having random reboots, with no particular pattern, couple times a day. What fixed my problem was updating my motherboard's bios from F9 to F10e. My bios must have been corrupted because I also noticed that I couldn't get to BIOS settings by pressing DEL key, as often as I used to be before. No crashes whatsoever now! I hope this tip helps someone out there who has similar issue.

I have the same problem with 10.13.6. I tried everything and it still reboots randomly... I'm not sure whether this is due to the system version. I saw someone in the YouTube says that 10.13.2 is the most stable version.

Update time guys.

I have 2 suspicious factors.

Either related:
---------------
1. High I/O
2. USB

Why?
-----
1. It often occurred when my Cloud software was syncing back and forth, e.g. Dropbox, StackStorage, Synology Cloud sync.

2. It also occured when I used Bluetooth and/or WIFI. I got the Half-card Broadcom BCM43xx.

For what's worth. The constant variable has always been mij NVME SSD, the Intel P600, 256gb stick.
It has never been the Graphics card, since I use onboard, AMD card, and now Nvidia.

Desperate attempt number 123421421; swapping out the NVME SSD for a normal SSD.

For quiet some time I don't have reboots. And I am using Bluetooth with WIFI enabled.

Maybe this information helps someone else too. Fingers crossed.

Not sure if anyone is still watching this thread, but ran into the same issues and they were as elusive as the OP's. Thought my PSU was going bad (10 yrs was a good run), then video card, but after swapping both, the issue persisted. The video card was the only thing I changed on my Z370 board.

I realized under light load that I was hearing coil whine from the video card, which is normally indicative of power fluctuations, so I assumed the video card was going through its power states and, when called to a power state, would reboot.

Sometimes would happen a dozen times a day, sometimes not for a couple days.

I solved it by turning *on* PCIE Native Control and PCIE ASPM Support. Haven't had a reboot for over 2 weeks now.

it drove me nuts for 3 years.

I exchanged my Nvme intel 600 256gb for a Samsung EVO plus Nvme.

Since than I didn’t had those reboots.

In the meantime I switched over to a Mac Mini M1. Hackintosh was Nice and fun but the new Apple silicon machines makes hackintoshing obsolete IMHO.

While I agree that is the eventuality, until GPU performance is better than a 5700XT, viva hackintosh.
