Question I can not get rid of the A2 error code on my Asus x299 deluxe motherboard (PLEASEHELP)

[ShaneMAATE]

Hello

Please help me i have been trying to fix this for days now with no luck at all

so i went to play coldwar the otherday because i had finished downloading it then it just did not open so i did a reset to discover my HDD had passed away, so then i just took it out like normal then i started to get an A2 error code and sometimes rarely that changes to a A9 code.
so the troubleshooting i have tried so far is

also i can boot into windows but i also get put into the megatrends page then i have to go into bios and choose the windows boot manger drive in boot options on the side

I have reseated the cmons battery also have installed a new one
I have booted with just one ram stick at a time with all of them
I have switched to HDMI from DP
I have tried with no GPU
I have tried without my boot drive
I have tired with no keyboard and mouse etc all that was taken out
I have updated bios
I have reinstalled windows 10
I have tried multiple different sata ports

I have baffled on what to do now
