OPEN GL, Help!

[MP 40]

Im getting that open gl error message when I try to run MOH, etc.
I know that I should download the Detonator driver, but how do I install it over the microsoft driver?

just install the driver like normal if you downloaded it directly from nvidia it should have an installer you can just run to install it...or goto your device manager, choose your vidboard, click update driver and choose the driver from there
