Hiya's,
I think i'm onto something with the nvlddmkm.sys problems
If you are having ctd or black screen lockups etc
What i would like is anyone reading with vista either x86 or x64 and all versions to post back with a yes or no answer to a few questions
1 Have you turned off UAC ?
2 Which drivers are you using (eg: 175.16 x64)
Post when you can so i can see if my theory holds true
Many Thanks
Ciao
