Question Hard drive and booting issues - PC is a vegetable

[PainRemains]

So in the middle of a game my PC suddenly turned off and restarted. It fell into an endless loop of running automatic repair and not being able to diagnose the issue. I noticed my NVMe boot drive wasn't showing up in the BIOS, so assumed it had died and removed it.

Reinstalled Windows onto a SATA SSD. Now while trying to download Steam games, I've had two BSODs. First said "critical process died". Second said "WHEA_UNCORRECTABLE_ERROR".

It now boots straight to BIOS, and the SATA drive is also not showing under my storage information.

Not sure what's going on, I'd already bought a replacement boot drive but now I'm thinking it might be something more serious. Ryzen 7600, 4070 Super, NVMe, 32GB DDR5, ROG B650A Gaming Wifi.

EDIT: Just now I made sure every single cable connected to the PSU was plugged in correctly. CPU cable may have been ever so slightly loose? Frankly it's 4am and I'm delirious at this point though so don't take my word for it.

After this it said Windows couldn't load correctly. I tried the troubleshooter and it said it removed some recently installed updates to recover it from failure. Now I'm downloading games with no issues so far, but not holding my breath.

- ROG Strix B650-A Gaming Wifi

- MSI RTX 4070 Super Gaming X Slim

- Corsair Titanium 32GB

- Ryzen 7600 + Thermalright Assassin Spirit

- Samsung 970 EVO 2TB NVMe (this is what I thought died originally)

- Crucial MX500 SSD

- Corsair RM850 PSU

I ran sfc /scannow and it repaired some corrupted Windows files. After this I put the Samsung Evo back in and it's working again. Used CrystalDiskInfo on all my drives and they're seemingly fine. So I guess it was probably a corrupted Windows install(?), although it's strange that I couldn't even get it to try and load Windows until messing with the PSU cables.

Surely a dying drive didn't cause this, considering two of my SSDs failed to show up in BIOs at separate points?

Try with single ram module.
