Brand new home-built computer and the keyboard isn't working

[MysticMaster]

Hi guys!

I was just about to install the OS on my home-built computer. The computer started as it should, with a menu popping up on the screen (BIOS, Boot etc.) and when I tried to enter the BIOS menu i couldn't because the keyboard simply wouldn't work.

I've tried to solve the problem by using different types of keyboards, like USB and PS/2 but it still won't work.

What should I do to solve this problem?

Try different USB ports.

Thanks for the tip but unfortunately it didn't work either. The KB:aren't broken since they work on other computers. If I push the ScrLk or the other lock-buttons a light starts so the USB-ports electricity are working atleast.

Hi, Try clearing the CMOS (unplug the power cord and remove the CMOS battery for few minutes).

I'll give the CMOS removal a shot. Thanks for the tip!

Weird. What motherboard and CPU?

 

[MysticMaster]

GIGABYTE GA-X79-UD3 with i7 3820

It should work. Try starting it with only CPU, CPU fan, graphics card. keyboard, mouse and a bootable USB stick (no HDD or SSD). If still the same... I would RMA the board.

I'll try that tomorrow have to go to bed now. Really appreciate the help!

Okey, I'm one step closer to a solution. I read another thread about a guy having the exact same problem as I do and he managed to solve it by using an older GPU. I tried using an older GPU and it worked. I installed the OS and then I figured I could change the GPU to the new one. I did this and when I did the screen still stucks in the MoBo menu becuase the keyboard is not working. Any thoughts or ideas?

Updating the BIOS (with the old card installed) might fix the issue, if newer BIOS version available.

I RMA the board yesterday. With the new MoBo it works like clockwork. Problably outdated BIOS that caused the problem but I thought it would be easier to simply change the motherboard. Thanks for all the help along the way guys!
