Take all your hardware out of the case and rebuild the installation on a cardboard surface or wooden table.Clear CMOS on the motherboard for defaults in BIOS.
Please do tell us what Power supply are you using ,as it can be a bad PSU in your case as well.

how do i clear cmos?

Hi there,
clear CMOS is a simple task of either shorting the CMOS pins (check your user's manual for their location) or by removing the CMOS battery from the motherboard and leaving it out for about 5 minutes.
If you have two of these boards and neither are working there could be an issue with the hardware you are using. It would really help if you could list all your parts and the correct model of motherboard as there is no 990f xa udg that I can find.

The problem you are having if it is a CMOS checksum error means that somehow the BIOS has become corrupt or flashed with the wrong version.
In either case you need to re-flash with a correct BIOS for your version of motherboard.
You need to make sure of first the model of motherboard, second the version of that model.
