My system has been running fine for 4 months @3.9Ghz but It started crashing. It will run fine if I do not overclock my cpu but if I try to overclock in the Uefi or with Ryzen master the system will lock up in I have to force it to shut down. I have tried resetting the bios, reinstalling windows and updating the bios.
