Well, I thought I should join in the fun and post yet another "it doesn't work" thread.
The game seems to run fine for a random period of time, then the PC either crashes completely to a black screen and auto reboot,
or; the screen freezes completely. No input is possible, ctrl, alt, del doesn't respond, a soft reboot is the only option,
or; the screen turns black, the PC freezes completely and again ctrl, alt, del doesn't help. The difference this time is that the speakers make a strange intermittent white noise pulse.
No crash log files are made with any useful info, although one entry in init.log says something about "NOT Using XML cache, failed to find crc.dat file". No idea what that may mean.
I'm using the latest drivers all round, also tried some of the tricks mentioned around here. No luck
I'm wondering what percentage can't reliably play this game... Here's hoping for yet another patch. 
EDIT: I did find a couple of weird entries in resmgr.log:
RESMGR: Texture PlayerColor01.tga failed to load
RESMGR: Texture PlayerColor02.tga failed to load
and Lsystem.log has a million warnings stating:
Node Leaf_3x1 has no generic art matching constraint xxxxxxx
building:Art/Structures/Buildings/Obelisk/Obelisk.nif does not contain a node called SHADOW. Its shadow, if present, will be corrupt! etc, etc.
