Working of memory (not had vista long myself) its "Start" then click on control panel. You then get a list, of which one should be System. Click on that one and somewhere in there is system details, click on that and it brings up your full spec. When I start up I get a square box that has various options to click on (ie internet) at the top of the box it gives some system details (ie ram) you can expand this box by clicking on it. It may be in there as well.
