Hello Vir,
I should still have the original, but because I've never had to re-use the OEM drive previously I might have wiped it already. I'm hoping I don't have to go there though.
An update on what I did - I rolled back my storage driver updates, and went back to using the generic Microsoft AHCI driver. I re-ran Driver Verifier, and it cleared the Windows logo without issue.
Here I am now, I ran DV and it didn't crash - so am I supposed to simply use my PC as normal now, and wait for a bluescreen crash? I checked in the processes under Task Manager and cannot see any references to DV - is there any way I can check that it is really running, and I'm not having some kind of brain freeze?
