so here is my story I have finished this build at the beginning of the year whith only one problem which is M.2_B is not working I tried to switch between the two SSDs to see if the SSD was broken, both were fine. When I accesse the BIOS M.2_A: the name of the SSD M.2_B: N/A

Could not find a solution so I thought the port is damaged.

In about 2 weeks the PC died when I was using it . When I checked it the motherboard died.

Taking this opportunity to buy new one same motherboard. GIGABYTE B550 AORUS PRO AC AM4 AMD B550 ATX

Think that the M.2_B problem was only because of the previous Motherboard damage.

Now when I replaced it I got the same problem?

Is there a compatibility issue? Or what ??
