Well, an update for anyone who's bored enough to read it.

From the beginning, my effing evga 8400 video card and it's drivers ruining my life.

The nvidia drivers kept crashing more and more, and I finally replaced it with another Video Card (Nvidia again) and everything is fine and faster than ever...no video driver crashes.

 

My CPU is still not clamping down to the MB properly, but even on the hottest days it's been no problem at all.

I feel this will solve have of my ennui with Poser, since Poser won't be crashing all the time anymore.

I still have not bothered to try to rebuild my content, though. If the Poser Fairy sent me a hard drive with about everything on it, I think I'd get back in. But now, I stare at Nude, bald V4, poorly textured V4. (Not really, but just about.)
