Maybe it has something to do with the CPU microcode update available in the F12 bios version, just a guess.
make sure your CPU cooling system is working....bad memory usually gives a GSD...can be also a bad video card is yours integrated to the mobo if it is u mite want to test it with any cheap GPU and see if u get the issue.
run sfc.exe /scannow install correct driver for video card if nothing changes, return it where You bought
