After successfully updating bios from P4.50 to P5.00 pc rebooted. After that pc started workin with black screen and no sound. 30 secs and it shutsdown for a 4 sec and then starts again. That is the loop. I have tried cl_cmos in few different ways, tried changing memory modules and slots (same memory), i have tried New PSU, i have tried unplugg all the cables (sw reset, led, sata, without m.2 ssd, front panel audio, usb etc.), tried everything with just 24pin and 4pin power cables. Bios could not be loaded, it is still in loop. All of the components are new, just bought - ryzen 3 2200g, HyperX predator 3000mhz, sx6000 m.2, AB350 PRO 4... Please if anyone has an advice i will appriciate,thank you. |

Unplug the system from power, press and hold the power button for 10 seconds, pull the CMOS battery and set the clear CMOS jumper to the clear position. Leave it like this for at least 2 hours before restoring the jumper to the normal position, replacing the battery and powering up. If you still don't get post after this then RMA the board, it sounds like the update may have bugged and bricked the board. Unfortunately bad BIOS flashes can happen sometimes. Good luck  -------------
