I am sorry to hear that have had issues with your motherboard model DH87RL.
Enabling Fast boot will disable USB ports until operating system is engaged.
I would like to know does this problem happen with an earlier BIOS version?
i couldn't try this, because I've flashed my Board directly out-of-the-box...
You can always downgrade BIOS version if you do BIOS recovery,
See instructions for BIOS recovery available below:
