The snag with any operating system is that it is designed in a manner so it will install on as many PCs as possible. For this reason, the drivers supplied are as safe and as tested as possible, and the operating system has only been optimised so far. Install the latest Windows Vista on your computer and the operating system hasn't been tweak, optimised and manipulated so it takes advantage of your PC and the peripherals attached. One starting point would be to grab the latest hardware drivers so that you have the latest drivers for your kit. The other option is to download a tweaking and optimisation tool.
TweakVista 1.01 is a tool that will analyse the software on running and installed on your computer and will see if they can be optimised so the system runs more efficiently. It will also benchmark your PC, check the startup applications and perform other optimisations. It's commercial and you might want to look at the free TweakVI for an alternative option.
