Before I begin, let me state unequivocally that I do NOT blame the problems I'm having on any of these three mods in particular, nor on the mods as a combination, since I know many others have NO issues running them.
What I AM stating, is that my SETUP has a problem with them, and I aim to get to the bottom of why, God and Mez/Kai willing
I've updated to the latest release drivers from Nvidia.
I ran an install of ONLY FWE...had only two crashes in an hour and a half or so, both in combat, computer froze for about two seconds, then crashed to desktop. Overall performance was at least an hour to 2 hours with no crash. Ran like this for two days, total number of crashes in 48 hours: 9.
I then ran FWE+WMK+a merge patch. Performance was not quite the same, although I had three crashes during zooming in/out animations, and two crashes while using Bullet Time and zooming. Ran like this for another 2 days, total number of crashes: 14.
Then I ran the full FWE+WMK+MMM+KH fixes+KH tweaks+KH hellfire fix+KH MMM override+compatibiity. I ran BOSS with the latest masterlist, then created my merge patch, made sure everything was checked.
MMM modules were: Main ESM and ESP+DLC's ONLY.
Data folder on this run was VIRGIN...only DLC's plus the files needed for FWE/WMK/MMM.
Result: average 4 crashes an hour

After two full days of running this way, I racked up a grand total of 51 crashes, three full lockups on quicksave, and three times when the game would not load at all.
I could post the load order again, but really, I checked it against Mez's load order and it's all ferpect, so I won't flood you with it.
Any thoughts folks?
Do the type of crashes ring a bell with anyone?
I'm running USB sound, so sound driver isn't the issue, and I have the latest Nvidia driver, since the last posts re drivers on the forums are several months and versions old.

If we can figure out where this is coming from, and why it seems related only to installs of mine that include these three mods, then it bodes well for everyone.
