I also fixed mine! I was waiting until I was sure about it.

On saturday morning my PC 'froze' 3 min after logging on FFXIV, after my hard reset and queueing into PVP I had a blue screen, so I just zeroed everything:

- I did a complete reinstall of my Windows with only my SSD connected (and later on activated my other disk and ssd in the windows Disk Management).
- During the Windows install I completely formatted ALL my SSDs and HDDs, even the ones I left deactivated. I didnt leave a single file behind.
- After the install, for my GPU driver I went with "custom install", unchecked all optional boxes, and checked the "clean install" one.
- I updated my Windows as normal in the Windows Update.
- Lastly, I also went to my BIOS and disabled my Memory RAM XMP.

Been playing all sort of games since saturday evening with zero problems.
Most importantly, I created a Restore Point on my windows as soon as I noticed everything was working as it should.

I hope y'all can find what works best for you, its one of the worst problems I ever had and I work with IT, ffs.
