Hi Dave. Are you sure that it's lack of RAM that your computer is reporting, and not virtual memory. I find that when the hard drive is more than 75% full, Windows starts giving problems. How nearly full is your hard drive. With new hard drives costing only about £30 for 40G and under £60 for 160G click here, a new hard drive is not too expensive. If you fit the new drive as slave and use it for storing all your documents and pictures, then fitting it is quite a simple task.
