keyboard problems

ok for just got new motherboard and processor on bios i have the os to power up my keyboard but when im gonna type my password to enter windows my keyboard seems to have no power, i know the cable is pluged in right (USB) and i found out that i have to pull the cable and plug it again for the keyboard to work. i have to do that evertime i start my computer..

and i even tried having bios power up my keyboard but i get the same results

any suggestions on how to fix this?

 

Have you updated the BIOS? Might correct it.
