What Windows version do you have? If it's Win7 or WinXP, you can try the Acer erecovery process, by pressing the Alt + F10 keys immediately after pressing the power button. A menu will appear asking if you want to re-set to factory new condition or re-set and save the data. Follow this video http://www.youtube.com/watch?v=H2xoMEPfiPQ

Report back with your results.

Thanks
