Dell XPS 12 9250 SSD Problem

Question

So I had been having problems with the stock SSD in my Dell XPS 12 9250 for a while, (It was the Samsung CM871, it kept corrupting my windows (and Linux!) installations and I couldn't boot to windows, it would often not let me create or resize partitions.) and I decided to upgrade/replace it with a Corsair MP300. It hasn't corrupted my Windows installation yet, it's been about a week, but sometimes the system will randomly not recognize it (It's not listed in the BIOS, and when I run diagnostics it reports 'Hard Drive not installed') and I'll have to reseat it. It is **bleep** in securely, so I don't think that's the problem. Another problem I've had is that sometimes the laptop will report 'No bootable devices' when booting up from shut down, and I'll have to go into the boot menu manually and select Windows Boot Manager from the UEFI menu. It does boot then. Sometimes Windows will blue screen, with a variety of errors, the only one I can remember now is CRITICAL_SERVICE_DIED. I'm running Windows 10 LTSB 2019 on it, perhaps that might cause a couple errors? I have all the latest drivers according to Dell Update. I'm beginning to think it's a problem with the mother board, but my laptop is out of warranty, so I'd have to take it to a laptop repair place or replace the motherboard my self. That's a decently expensive repair, so I'm coming here to see if there could be any other possible causes. Please give me some good news! (Or some alternative repairs!)

First hunch with those myriad of problems, replace the CMOS battery (coin cell). But before you install the new battery, leave the battery out of the system for 15 minutes (Intel recommends 30).

Now you could also have corrupt Windows files, so download the Windows 10 media creation tool and when you boot from the USB select repair.

Thank you, I'll try the CMOS battery - Do you happen to know the size? I dont think it's the windows installation, I've tryed reinstalling multiple times.
