Sounds like something really went wrong . Where you having problems with the hard drive and decided to buy a utility to help fix ?
Regardless , I would think your hard drive failed . In that case Im not sure. You could try the recovery cd , or the windows cd that came with the laptop.
first try turning on computer and while its booting up repeatedly tap the f8 key , then select "safe mode" if you can get into safe mode then
go to start menu , right click on "run" and run as admin . then in the black box type sfc /scannow . it will look for damaged files and then ask you to insert windows cd to repair them . if you have a failed hard drive then you might want to have it replaced and reinstall windows
