Question Diagnosing crashes, SSD not detected, disk write error

About a year ago, my PC failed mid-game and turned off completely as if it had been unplugged. After researching, I determined in was a PSU failure. I bought a new PSU, but my PC continued to have problems. It could not detect 2 of my 3 SSDs. On the SSD that I could detect, I formatted it and installed windows. It had an error while installing, but after I re imaged the drive several times, I got it installed and booting fine. I still cannot detect my extra two SSDs, which I have tested on other PCs as well (they are both fine). I tested multiple SATA and power cables, the cables were not an issue. I updated my BIOS, and still could not detect the two drives (in BIOS or Windows). But there are other issues too. When I try to install some games, I get disk write errors. Recently, I started getting blue screen of death when installing the latest Apex legends patch. I had errors trying to install some Adobe programs as well. I cannot figure out what components might be causing the issue-

  • SSD: Disk write errors, crashes, and blue screen of death could suggest issue with the drive. Samsung Magician says diagnostic is not available for this model, but that health is "good."
  • Motherboard - BIOS cannot detect my two SSDs that I know are fine, even after update.
  • RAM - Bad ram could explain some crashes, but not that my SSDs are not being detected.
Is it some combination of all these components? Why would these issues only arise after PSU failure? Any suggestions would be really helpful.

My parts:
MOBO - MSI Arsenal Gaming Intel Z170A LGA 1151 DDR4 USB 3.1 ATX Motherboard (Z170A Tomahawk AC)
CPU - Intel Core i7 6700K 4.00 GHz Unlocked Quad Core Skylake Desktop Processor, Socket LGA 1151 [BX80662I76700K]
GPU - Gigabyte GeForce GTX 1070 G1 Gaming Video/Graphics Cards GV-N1070G1 GAMING-8GD
PSU - EVGA SuperNOVA 750 G2, 80+ GOLD 750W
RAM - Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz C16 Desktop Memory Kit - Black (CMK16GX4M2B3200C16)

SSD (Functioning, with OS) - Samsung 860 EVO 500GB 2.5 Inch SATA III Internal SSD (MZ-76E500B/AM)

SSDs (not detected, but tested successfully on other PCs) -
- Micron MTFDDAK2T0TBN-1AR1ZABYY 1100 2 TB 2.5" SATA 6Gb/s SSD Solid State Drive
- Samsung 850 EVO 500GB 2.5-Inch SATA III Internal SSD (MZ-75E500B/AM)
 
for ram errors u can use memtest utility
if u get 0 errors, then your sata controller should be at fault
u could either use another sata controller or replace mainboard

cards looks like this, if u choose another, make sure it has bios so u can boot drives from it
also in your bios (if u have modern uefi), make sure that legacy (optional) bios roms are enabled and uefi boot is disabled
