I have even tried plugging in my ssds in a different system but that system to BSODs and the error says "boot drive inaccessible".
I had a similar problem, it appeared to be due to using an older version of Display Driver Uninstaller, maybe 9.7.something... It had screwed up my registry pretty badly, and one of the listed fixes in DDU 992 was for a 'huge' registry issue (apologies if I am misquoting, I can't make my way back to the page in question).
I'm afraid I wasn't able to do anything but reinstall Windows. If you have a recent registry backup it might be worth trying.
