My Wii functions but games work wont! Help please.?

I hacked and installed Homebrew about two years ago and for more than a year it has worked fine. Before now it would work OK. I usually could play the games however occasionally while starting a game it would mess up. There would be an error message saying to eject the disk and turn off the Wii. The message would pop up a few times we would restart the game and then it WOULD work. Now for EVERY game I put in there (besides Gamecube Games) this happens and I can't play any games. Technically the Wii itself kind of works since I can play WiiWare and Virtual Console games however I can't play any DISC games unless it is Gamecube.
