Startup Repair: Recover Your Windows 7 & Reset Password

Help: Windows 7 won't boot up!

I am completely unable to boot into Windows 7 either normally, or through safe mode. Running a boot disc and trying to reinstall doesn't work either.
When trying to enter Windows 7 normally, it gets to the splash screen with the animating windows logo and just sits there.
When trying to enter Windows 7 Safe Mode, it gets to the screen where it tells me it is loading drivers. It gets as far as "CLASSPNP.sys" with "Reading Windows files" at the top of the screen and then gets stuck.
When trying to reinstall Windows 7 from boot disk, it tells me it's starting Windows installation and then sits there.

I have quite a bit of experience with computer but I am at a total loss as what could be wrong here. Any help would be greatly appreciated.
