Hello. I have a random crashing problem on a 2017 820-00165. It has crashed during startup and the other day it froze for about 8 seconds after running for more than an hour, then powered off. I ran Memtest through the 4 passes and no errors were reported. The board is clean with no corrosion or previous work anywhere. I'm hoping someone has seen this before. if this is not enough I can provide more.
Below is part of the crash report.
