Did you receive any new BSOD after you updated the Bios?
If you didn't receive any new BSOD, the update of Bios might have fixed the problem, and don't need to do any further steps.
If you are still receiving the BSOD, try to reset the Bios settings to the defaults.
1-Power on your computer while pressing the Del key repeatedly to enter on Bios
2-Press the F6 key to load the optimized defaults and confirm that you want to load the defaults
3-Press F10 to save the change and reboot your PC
If the problem persists, please share the new minidumps.
