Installing win7 won't expand files

[AfterTheUndead]

So i booted from my win7 install disc, got to the part where i formatted my hard drive, and started the install, but at the "Windows is expanding files" part it doesn't move past 0% and i get this error that says that something may be corrupted. This doesn't make any sense to me because I've had the computer working for almost two years now, and reinstalled win7 with the same disc multiple times. I have no idea what the problem could be. Any help would be greatly appreciated, thanks

This will often happen if the disc gets any cosmetic damage. You should clean off the disc as much as possible, then try to reinstall.
