display adapter?

[Krazed]

try this:
right click desktop
select "Nvidia Control Panel" from drop down menu
select the category "manage 3D settings"
In both tabs ("Global settings" and "program settings") change the preffered graphic selector to high performance Nvidia processor

If that doesn't work, I suggest trying to download new drivers from nvidia directly. Followed by:

Uninstall your current driver through the control panel.
Restart and boot into safe mode (F8)
Run Driver Sweeper
Restart and boot to the regular desktop
Install the new driver
Restart
