Well for a start, you can't install windows 7. It is only beta at the moment.
If you do, then in a couple of months it will not work & you will need to go back to Vistahttp://www.microsoft.com/windows/window ... nload.aspx
Watch the calendar. The RC will expire on June 1, 2010. Starting on March 1, 2010, your PC will begin shutting down every two hours. Windows will notify you two weeks before the bi-hourly shutdowns start. To avoid interruption, you'll need to install a non-expired version of Windows before March 1, 2010. You'll also need to install the programs and data that you want to use. (Learn more about installing Windows
If you want, create an image, or keep the recovery disks for Vista.
Try installing XP, you will then have to hunt for XP drivers. Search the forum about XP drivers. Someone has made a pack for one laptop.
Use anti virus, backup your data, use google.
POST BACK EVEN IF THE HELP DOESN'T HELP.
A Thank You would be nice if I have helped.
