You most likely need to experiment with various cheat codes.

The first one I would start off with is testcd. This will tell you if your cd is corrupted.

If your cd appears to be ok, then try booting with the failsafe option. This gives you very little hardware support. But if it works, then you know that you simply need to go back and try out the other "no" cheat codes to see what the offending hardware issue is.
