having trouble getting a computer I just built running. Beep error is 1 long 3 short. I checked the RAM, even took out the existing, put in different stick from another computer. Replaced the vid card with one I know for sure works, still gives me the error beep. Bad motherboard? (using Gigabyte board)

it says "keyboard error" which I don't understand; used a couple different ones and kept doing the same thing. But, I cleared the CMOS and now it starts up and able to enter BIOS
