Recently upgraded my BIOS, and since then my windows10 installation has very frequent crashes (lockup or just reboots). Same system has been rock solid for over 1 year now, so 100% sure it's the bios update. Problem is, I cannot seem to find specific things in the event viewer which explains the lockups so kinda at a loss here. Any tips how to narrow this down? Nothing is OC'd.
Intel i7 9700K
Core speed: 4638mhz
x46 - 100mhz bus
Mem 4334Mhz - 16/18/18/36 (Corsair DDR4-2132)
MSI RTX 2080
512gb NVME2 SSD + several SSD's
Win10 reports critical error (kernelpower), about 2 times today (10.26am, 16.00pm)
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
