We have a gateway nv59c66u laptop here that was having problems and we were told it was the hard drive. We purchased a new hard drive, and successfully installed windows 7 home premium using the recovery discs. All drivers installed correctly since there are no exclamation points in the device manager that say otherwise. However, once the laptop is restarted, it will not boot past the "starting windows" screen. I see the little window doing it's flash that it does while loading, but never gets past that part. I read on another forum that it could be a bad install of windows, so I used another windows 7 home premium disc that I had, everything installed great again, all drivers installed perfectly again, restart the laptop and the same problem!!! The laptop is not very hot at all, and the fan is working so I do not believe it is over heating, I have not received any blue screens of death, so I am completely stumped. The only thing I have not tried was new RAM. Could I have received a faulty hard drive? Any help is much appreciated!
