did i just break my pc or something?

No, you just have a software program installed which is conflicting with the protection on the game.
The only way to find out which program is causing the conflict is by uninstalling them one at a time then trying to start the game again by using the original game disc.

Uninstall programs like Alcohol, Daemon, CloneCD, AnyDVD etc. (basically any burning or emulation program.)
You will eventually find the cause.
