Just wanted to add that the drivers you are missing are the most common to be missed - when people reinstall an OS - they forget to run the drivers disk, normally the MOBO disk, but on a laptop its a drivers and utilities disk - when you install or reinstall an OS the driver sequence should always be:-
Latest Service pack (if any)
MOBO driver disk/drivers and utilities disk (or the latest ones from the manufacturer)
GPU drivers (from NVIDIA or ATI website)
