Windows 7: Problem with Aero?

Hello again and my apologies for posting due to my problem.
So recently, I have done a fresh install of Windows 7. I have also gotten my drivers updated along with the necessary programs installed too like anti-virus, etc. But why I have noticed is that whenever I were to exit the program using the red cross, it will have some 'lag' issues but it doesn't happen on Alt+Tab or minimizing. Any help would be appreciated. Sorry for my poor explaination. And thanks for viewing and replying.

No apologies...that's what we are here for.

I'm not very familiar with Nvidia chipsets, but do they have chipset drivers that need to be loaded as well? If the board was an Intel chipset, I'd suggest loading the Intel Chipset drivers.

Ty, DeaconFrost.
I only download the drivers from the website and installed in according to my card. I have been doing so for the last few times so, I don't really think that there is any chipset or is there which I'm not sure of. I've installed the Intel chipset along with other audio drivers as well.
