Sounds like the OS is messed up. You should have gotten either a restore disk with your laptop or there should be a restore partition on your laptop to restore your windows. You will loose all your data though. If you need your data or don't know how to do it, I would suggest a repair shop that would be able to pull out your hard drive, copy all your data, reinstall your windows, setup your drivers, and put your data back. Call around though, some places rip people off for that kind of work. My place only charge $40 to do all that. Some places can charge up to $200 (cough, Best Buy, Future Shop).
