When I open my PC to check system information and bios it doesn't let me enter. It shows me which button to press but it does not recongise it when I press it, although my keyboard is lighted up. It stays at the motherboard screen for a few seconds and then says "didn't find bootable device" . I am not installing windows yet, I wanna check if every part of my pc is working. Also, my keyboard worked fine on my other computer. Could the USB connectors be fried ? I tried pluging the keyboard to the front ports as well. Or the motherboard doesn't have the ability to use a keyboard to enter bios ? I'm using a Gigabyte 970-DS3P AM3+ with FX6300 and 8GB KINGston memory. The system is in a corsair 200R with a r9 280,xfx 550W core edition and crucial 120GB SSD.

Loose connections could mean anything? I shut the psu off and re plugged the power switch, the 4 pin CPU cable, the 24 pin the gpu cables. Also, it was booting a minute ago. It stopped booting when I repluged earlier the CPU cable. ( before you told me to check for loose connections, I repluged it again now)

I would disconnect everything and test bench it but i don't have that internal speaker. Is there another way to diagnose?
