Recently, my PSU failed while in the middle of something. I replaced the PSU and now I can get past the MB splash screen (MSI 890-G65 for reference, an AM3+ board) but it no longer sees a boot drive. In the BIOS utility, my 500 GB WD drive also doesn't appear. The OS is on the 128 GB SSD. What might be causing this failure to detect the drives?
Outside of reseating the sata cables, I'm not sure what else I can do besides testing the drives with other hardware, which I currently do not have access to. At that point I would need to take it into someone to test them. I'm concerned that maybe the SATA controller on the board also failed, but I have no way of verifying that.
Is there anything else I may have missed?
