I had been running backups on my Wii for almost 3 years. I've never had any issues with running games. I hacked my 4.3U Wii with Indiana Pwns and it worked ever since. A couple of days ago I started to play my back up of RB3 from my HDD. The screen froze on a song with a couple seconds of the song on a loop. I turned of my Wii thinking nothing of it, but when trying to play the game again it didn't want to load. I tried to load other games from the Home Screen (through the use of wads) and from both Wiiflow and USB Loader GX. Wiiflow was stuck on the loading screen and USB Loader GX kept on sending me back to the homebrew channel when I tried to load something. The games that I launched from the Home Menu sometimes work fine until a loading screen where they freeze and I need to restart my Wii. I'm thinking of cleaning my Wii, maybe that's the case, but I'm not sure. I don't really know what other info should I give.
