If you call a support person, give them this info:
Stop code: IRQL_NOT_LESS_OR_EQUAL
It counts to 100%, reboots, and everything looks fine again until the next time. Ive already run Windows Update and teh system tray says all drivers are up to date. I honestly dont know whether to blame the hardware or the software at this point. Where do I even start with this stop code? I can run commands and install tools if someone points me in the right direction. I just dont want to wipe the whole home-built Ryzen PC and lose a weekend if this turns out to be smth simple.
