You can download and install windows vista

Hi gemm71,
You can download windows vista from the following link:
http://en.community.dell.com/support-forums/software-os/w/microsoft_os/3317.2-3-microsoft-windows-vista-official-iso-download-links-digital-river.aspx
Just flip your laptop and you will find an sticker which has the original Product key for windows vista that was there on your this computer. When during the installation it asks you to enter the product key do enter this product key and you will have a fresh copy of windows vista on your machine.
Please keep me posted whether this fixed your issue or not.
