Experienced builder here. I have this weird issue that started a while ago after having no issues whatsoever where my new-ish pc shuts down from time to time after posting. When I reboot I get no issues. Also during use and when waking from suspend there are no issues. I swapped the SSD but the problem persists. It must be some kind of power failure but my PSU is a good one (Seasonic Focus Gold). At 550W it's plenty powerful for my rig with Ryzen 3600 and 5700 XT plus one NVMe SSD. I posted my minidump on the Windows forums but noone there replies. It could also be the power button on my Fractal Define Mini C TG but I doubt it since it's a quality case also. My CPU/RAM are OCed but I'm not new to this and both OCs are tested stable. The CPU is actually undervolted to keep it cool and quiet (4.1GHz@1.125v) so no crazy voltage involved either. The RAM is just OCed from 3000 to 3200 MHz with no timings changed. I have no idea so far.
