My Wii is a few years old, not launch but from around there. It has system menu 3.1u, I haven't used the the thing in years and recently installed bootmii and hbc through the twilight hack. Blah Blah I tried installing the Rock Band 2 dlc crack and ended up with error messages. I gave up/stopped caring and just played RB2 like normal then the game freezes up and starts buzzing loudly. The disc ends up being scratched and loads very slowly, then freezes. I tried formatting an sd card to play customs with rawksd and it freezes before I can finish. The main menu on the wii freezes at random now. I don't know if it has anything to do with something being installed improperly or what. I tried to restore with bootmii but it says it can't read nand.bin, and when I tried backing up again it froze in the middle of it. Now it says nand.bin is from another wii. Someone suggested the freeze/buzzing is due to overheating but it happens right away after days of non-operation. Does anyone have any idea what this sounds like it could be? If it's software related, what could I do to find out/fix it? If it's hardware, am I screwed? Any help is appreciated, thanks.
