[rodtoo401]

I have picked up a Gigabyte GV-RX570Gaming-4gd rev-2.0. I have narrowed the problem down to a bad NKS GS7103 ,RFG7LAKVS. I can find the GS7103 all over the web.Here is the problem ,the number below the GS7103 does not match the one that is bad .That number is RFG7LAKVS closet I can find is RFG7LAKWA. Thanks at this point I am pulling my hair out. SO what will work is what I am asking .
