Unplugged SSD and HDD and after plugging them back pc doesn't boot properly

[qummel.kim96]

I was trying to fix problem with my Gigabyte aorus gaming 370x k5 because i couldn't acces bios.

i took out the cmos battery and unplugged my external drives. After that plugged them back and restarted my pc and got an message "reboot and select proper boot device"..

funny thing is i can't enter my bios or anywhere else and also none of my usb are working anymore so i can't use my wired keyboard..

and that makes me stuck with the message "reboot and select proper boot device" without acces to bios or anywhere else.. also it's a 6 week old pc build that was working perfectly until the bios stopped working.

any solution to this problem?

Well a BIOS has a default USB composite driver so you can use keyboards and mice in the BIOS.

You may have a faulty board if resetting the BIOS, via removing the battery for a minute, didn't work.
