Cyclic Hotline,
You can also set your Virtual Memory Min and Max sizes both to 384Mb. That will free up some space on your Hard Drive by reducing and making your Pagefile a static size.
Next thing would be to disable Hibernation. You will see a file in your Root Directory called hiberfil.sys which takes up the same amount of Mb as you have RAM in that Notebook.
Take Care,
Richard
P.S. Then I would go though Add/Remove Programs and Uninstall anything you do not use.
