ASUS Maximus VIII Hero Alpha Bluetooth Disappeared

[Mikster5000]

Hey All,
I am experiencing and issue with my Motherboard and i wanted to see if anyone else has had this issue or know how to fix it.
I have an ASUS Maximus VIII Hero Alpha board. The Motherboard is two years old and Ran with no issues until Last weekend when my Bluetooth device just disappeared. I have tried reinstalling drivers , Updating Bios, reinstalling windows, etc... No luck, Windows just does not detect the Bluetooth device any longer. Antenna is attached and wifi still works fine.... not that i use it much.

Another issue that is happening is When booting up it gets stuck on the ASUS ROG Post screen. A Reset will resolve this but it is annoying.

Specs:
I7-6700k (Not OC)
ASUS Maximus VIII Hero Alpha Board
32GB RAM
GTX 1080ti
CoolerMaster 850 Gold PS
500GB SSD bootable
2x2TB HDD


Any help would be amazing!
Thanks!

Not sure if it will help but last time I had this problem. I reflashed my bios again using the USB Flashback feature. Then I just installed driver version 10.0.0.709 from a third-party site. Haven't had any problems since win 10 build 1709.

I still occasionally get the issue with board not reading any UEFI devices which will the boot into the bios. Sometimes if I exit the bios, it will find my boot devices again and boot up. otherwise need a reset. Still don't know what's the issue is. Changed psu and ram still same issue.
