  • Hi everyone, I'm writing out of curiosity as I think I've now tried everything without success, I basically installed the bios version at 816 and when I want to update to 904 onwards the q code of the motherboard goes up to the b4 code and restarts the cycle there is no way to start the PC while if I go back to the bios version 816 everything works, I heard about USB but I disconnected everything both internally and externally bios battery reset etc nothing I wanted to know if anyone has found a solution miraculous
