Troubleshooting Qcode 00 on Asus Rog Strix X670E-E
Doing nothing special my PC suddently shutdown and was stuck in the boot process with the Qcode 00, in the manual the code is “not used” ^_^ Power Off / Reset nothing was working.
Clearing the CMOS was the solution, I still don’t know what was the cause, but I am not alone. I have updated the bios hopping is will not happen again.
