Question from Travis:  I have a Gateway desktop computer that got struck by lightning.

I also have an old HP desktop that had a bad hard drive. Both PCs ran Windows 7.

My cousin connected the hard drive from the Gateway to his computer and the drive seemed to be working fine, so I replaced the bad hard drive in the HP with the one from the Gateway.

But now after switching the drives, when I turn the computer on Windows won’t boot up. All it does is display a blue screen with an error message on it.

What do I need to do to fix this?
