Right click at desktop and select Nvidia Control Panel. From 3D Settings make sure than the nvidia card is set to run anything. To see if you have a nvidia card, what model is your computer exactly?

There isn't an option "Nvidia Control Panel".

My computer is a Dell Inspiron 620 MT with 4gb RAM. It has a Intel Graphics card, a HD one I presume?

I have a Windows 7 Home Premium 64 bit.

All drivers are up to date, (as far as I know).
