System:
Asus Rog Strix B550-xe mobo into a Asus Rog Strix B550-f
Amd ryzen 9 5900x (no oc'ing of this, ram or GPU)
Corsair Vengeance 32g 3200mhz DDR4 Ram
GeForce 2070rtx
Samsung 980 Pro 2TB M.2 NVMe SSD
Windows 10 Pro
I'll be as succinct as possible: Custom built PC that, one day upon returning home, was in the BIOS. The mobo had an A9 error, and my nvme was not listed as a bootable drive although the BIOS could see it.
There was nothing preceding this that indicated any problem.
I tried a number of different things, including swapping slots, changing boot options (CSM etc), and running a self test in BIOS. This would always result in hanging. The longest I left it for was about 15 minutes before restarting.
Eventually after some more fiddling, the computer wouldn't post after a D0 error. After some slot and ram swapping, it eventually posted right back into A9 again. This led me to believe it was a motherboard issue, so I got a tech around to have a look. He tried some of the same things and, after also trying to flash the bios in which nothing would happen (no error, just went back to the previous screen), and trying to see if the disk could be read through a windows recovery USB (it could, it detected the w10 installation), he said it's more than likely the mobo.
Thus, enter the new mobo with the same issue (the ram is fine with this board, though). The nvme SSD is detected but is not selectable from boot options. I can access the directories through the BIOS flash utility, so the file system seems intact. It still hangs the BIOS during self test. The only difference was I got the fTPM warning during boot (it said it detected a new CPU). Initially I selected no, it then restarted and kicked me back to BIOS once more. Disabling and re-enabling fTPM does nothing, and I also tried selecting yes to the same result.
So aside from just getting a new drive to see if that works, is there anything else I could try? Could this also possibly be a CPU problem (the tech floated the possibility)? Any help much appreciated 🙏
