@terrymcd biggest issue here will be the display driver. dell does not provide any approved ones for your model. There are work arounds so you could in thoery update to Win 7 at least. However you can upgrade your memory to max it out and also optimize your hard drive. Just because there is no longer support for Win XP does not mean you have to stop using it. You can get lots of anti virus for Win XP so you can safely connect online.
