Crashes every 5-15 minutes

Glad that culprit has been found.

It seems like ThreeDee was on the right track.

I ran Prime95 (small FFTs) for about 20 minutes before it crashed. Then I booted to Ultimate Boot CD from a USB and ran the Mersenne Prime Test (small FFTs). It was still going 5 hours later.

I swapped out the SSD for an EVO 960 from my main rig (same M.2 slot), and ran Prime95 again. It's only been 30 minutes so far, but that's the longest Windows uptime I've ever had on this machine.

I'm going to let it keep going for another 12 hours just to be sure. But it seems like either the WD Blue SN550 is faulty, or it's somehow incompatible with the board. I'll plug it into my main rig after I'm done running Prime95 and see what happens.

By the way, thank you everyone for the suggestions.

I can try running Prime95, but I can guarantee you it will crash, given that almost everything does.

Memory in slots A2/B2? .. are you able to get the latest chipset drivers installed? Does it ever crash just sitting in the BIOS? Have you tried a different drive to install windows on? Have you tried the other M.2 slot? Have you checked the drive in another PC or for errors? Was the TIM you used non-conductive?
