I keep getting the post code/Q code A2 which means it can't find my drivers which makes no sense to me because when I put my Drivers back into my other PC, its boots up just fine, any recommendations, I'm headed off to work right now and will check the replies later.

Drivers are not loaded during POST. Drivers are loaded when windows loads.
when I put my Drivers back into my other PC
How in the world do you put your drivers in another system???
Are you by chance referring to drives ie hard drives? Drives and drivers are two very different things.

OK, if I understand your post, you cannot see any drives in the bios. Do the following;
1 System OFF and pw cord removed
2 Reseat both the sata data cable and the pw connector. Be sure both ends ie motherboard and drive have been reseated
3 Pw ON and enter the bios. See if your drive is detected. If not, shutdown and try another data cable. Try a different sata port. If it still is not detected in the bios, either the drive OR the motherboard controller has failed

Be sure and try a different sata port. Since you have a M.2 drive, sometimes a sata port is disabled when you install a M.2 drive.
Be sure your sata ports are enabled in the bios. I checked your manual and it is pretty much useless. The paper manual that comes with your board may be better. Read the manual and see if you can enable/disable sata ports.

If you are not seeing anything on screen, are you using a 4K monitor?
