I think I may have fixed it. Time will tell. Here is the article. Seems like many people that have the NVIDIA 8000 series video cards are also experiencing this.http://www.vistaheads.com/forums/microsoft...ecovered-3.html
I did everything that was mentioned here:
"I have found and fixed the problem today. This is what appears to
during the installation of the most current drivers 100.65 Vista, an
nvlddmkm.sys is copied into windows/system32/drivers and not the
in the install. As a result the new drivers are attempting to access a
dated 11/2006 instead of 2/2007 ver 7.15.11.0065 which is in the newest
driver ver 100.65 vista 32.
Fix: Go to windows/system32/drivers and rename nvlddmkm.sys to
nvlddmkm.sys.old. Go to the nvidia directory and find the file
and copy it to windows/system32. Using the cmd window (DOS box) type
EXPAND.EXE nvlddmkm.sy_ nvlddmkm.sys. When the expansion is complete,
the new nvlddmkm.sys to windows/system32/drivers and restart the
Your computer should now work properly.
You will notice that any uninstall and reinstall of nvidia drivers will
remove the old nvlddmkm.sys file and will not overwrite it with the
version. You have to do it manually. I do not know why this happens
cares as long it is fixed."
