Turns out my Dump file was outdated, my crashes were caused by XMP profile not being liked anymore. Despite passing memtest86 for four passes. Do you get a Critical Kernal crash could be worth trying?
@jds63 Are you on Nvidia driver: 511.23? I think that's problematic at the moment, it might be worth rolling back to 497.29 or try going to a latest if exists.
@jds63 I'm having the exact same issues and basically followed everything you did. I also bought a new PSU and that did nothing. I hope this gets fixed soon. Is there anything you need from me to try and debug this issue?
