I updated the BIOS on the ASUS M5A99X EVO motherboard to Version 1708. after installing the new BIOS update, when booting the computer it gets stuck on the ASUS Motherboard logo screen asking me to press DEL to enter the UEFI BIOS Settings. But it wont respond to anything that I do, I've tried multiple keyboards. I have tried removing the battery to reset it, but nothing. the Boot LED is on the entire time. can anyone help me?

I'm back, after restarting my computer again, it seems to be stuck at the ASUS Motherboard logo screen. I have tried moving the jumper and removing the battery but both solutions no longer work. is there anything else I can try?

it seems to be conflicting with my external HDDs. when they aren't plugged in, the computer boots just fine. but when they are plugged in, the computer will freeze at boot. I have tried plugging them into different USB ports, but nothing changes. This has never happened before, only after updating the BIOS version.

I don't remember the exact BIOS version number to go back to. and is it that easy to downgrade the version?

EDIT: I have downgraded to the version before the one I was having this error with. now everything seems to be fixed, and the computer can boot while the hdds are plugged in.

Thank you for all of your help! :)
