So when I first got halo 3 I tried playin the disc and when it loaded no words showed up on the main menu. I can't messing with it the words finally showed up but when i would try and play campaign the disc would load half way and then an error would show up and failed to load and cannot load something to that affect. So I tried taking off my hard drive and was actually able to play. Tried to play online in matchmaking and everything would load would have enough people to start a game, map would start to load and then send me back to the lobby. Any ideas on how to fix this problem, its driving me nuts. Thanks for all the help.

is the disc clean and free of scratches? try clearing your cache?

where did you buy it? if locally, just return it for a fresh copy. if the problem persists, call Microsoft and see what they say.

how do i clear the cache?

im not sure if this clears anything besides game updates, but you can try.

This is actually problem with a lot of Halo 3 discs... (mostly the Standard Edition discs but I've heard a few Limited Editions were effected as well)

Basically it's a manufacturing defect that makes the disc act as if it's all scratched up

take it back to the store for another one, or contact MS and they'll replace it for free. it was reported all over the place I'm surprised you didn't hear

I hope you didn't clear your game updates like ILG suggested... not only is completely unnecessary for Halo 3 (since there are no game updates for it) it's a total pain in the ass to update absolutely every game you put in the console after the fact.

I had no trouble with my halo 3. Works perfectly fine.
