So ive been having some issues with my pc, with gpu drivers etc, so i took the step of updating my motherboards bios, i finish the bios update and redo my old settings.

Proceed to boot the system after finishing settings and get the fan speed ramp up and slow down like its trying to post it does it again fan speed slows down and no video out.

I wait 20min before rebooting i get video out but im prompted with a bios recovery. I do the recovery steps reinstalling the bios from the flash drive.

Everything goes smoothly i get to windows remember i forgot to change the ram profile and restart while in windows and again the pc does the same weird boot issue.

The only further troubleshooting ive done is reset the cmos since then but the issue still persists on resetting the pc from windows.

Any advice would be appreciated.

Running windows 11, ryzen 7 3700x, asus prime x470 pro

Look at the motherboard LEDs while its booting. Any lights that are lit or flashing?

All motherboard rgb is on but i dont think theres any debug leds on the board, well if there are theyre not making their presence known.

#

After i hard power down after an attempted reset it boots into safe mode

See if you can boot to the OS, I would overwrite the bios again

#

maybe the bios did not update correctly

#

I can boot to the OS on a clean startup just fine

#

The issue is from windows restart

#

I restart the system its like it doesnt fully shut down i dont get the momentary fan slow down

I kinda read into this. some users removed the battery for 15 minutes and some loaded optimized defaults

#

I would try with the optimized defaults and then remove the cmos for 15 mins
