Updated to BIOS and chipset driver mentioned above: Problem still exists Happens irregularly again and again, sometimes after minutes, sometimes longer: Windows freezes for a few seconds and then the PC reboots. After 20 min the first crash/restart with the following entries in the Event Viewer: WHEA-Logger ID 18 and critical error Kernel-Power ID 41. Today I installed a Ryzen 5900x and a Scythe Fuma 2 CPU cooler.
Worked with the included AMD Prism Wrath CPU cooler for one week without any problems. I first assembled the PC with a Ryzen 3800x a week ago because it was unclear if and when I would get the Ryzen 5900x I ordered.
OS: Win 10 Pro (64bit) - all updates installed PSU: be quiet straight power 11 750w Platinum Graphics: SAPPHIRE Nitro+ Radeon RX 5700 XT
