I can't enter BIOS by hitting DEL or F2 as prompted on screen when boot up. the scrren shows nothing and Qcode shows 00, tried everything to fix this.

1. enter Win10 advanced boot option and select boot UEFI, no luck
1. clear BIOS, rermove battery, no luck
2. downgrade from 1002 to 1001 or 0902, no luck
3. unplug all the HHD/SSD, no luck
4. plug my graphic cart(evga 1080FTW) to 2nd PCIE slot, no luck

I have search the web for this issue, seems like it is caused by fast boot option, any chance I can disable it outside of BIOS?
