If possible, please let us know which ASUS desktop model you have and which bios version you are running since we have a separate sub-forum for the motherboards we sell separately, so want to make sure you are not asking about them.
Really just want to know if you have an ASUS desktop system sold complete or an ASUS motherboard sold separately if you want to provide your ASUS desktop model or motherboard model to make sure you are posting in the correct section since this sub-forum is for the ASUS desktop systems sold complete and not the motherboards sold separately.
If you are able to boot into Windows, you can check the bios version there, but assume you aren't able to do that either.
I called Asus customer service and found a solution that worked on me. Go to Windows Settings on the system click on recovery after that click on advanced startup option, your computer will restart, don't worry if you see password screen again just enter password you've entered before. You'll see blue screen with options follow this line Troubleshoot>Advanced options>UEFI Firmware Settings and restart. Type your password agian then you'll go inside the BIOS. If you want to remove this password go to place where you add password and click on it enter your old password and leave blank the new passwords. I hope that will help you guys^^ Thanks.
