Hi all, thank you for any help or suggestions you have. I have the following setup:

Crosshair VII Dark Hero
5950x
2x 3900 FTW3
2x16 g.skill 3600
evga 1300 G2
W11
980 Pro 1TB

I had installed bios 4006, but since I could not get it to boot with q code 97, I went back to 3801. But that gave 62 code, I did try different ram, but that did not help. I finally put in an old 750ti and the system boots fine.

So, any ideas what this might be? It would seem to possibly be an issue with the MB. I have unseated and reseated nearly all cables on the MB and tried swapping out GPU power cables.

My start to all of this was having issues with my 2nd 3090 fans 2 and 3 not working all of the time, so evga is in the process of swapping that one out. But otherwise, I am currently at a loss as to other ideas.

Thanks, once again, for any help you can give!
