Wii makes strange noise when trying to play games

That's the capacitors inside the system. When capacitors aren't solid state they will make a high pitched noise while under load.

actually this isnt the guitar this is the system. the disc is probably scratched and can be buffed out at game shops, or you can actually buy game buffers at places like Wal-Mart.

you may need to get a trigram screwdriver to undo the funny screws in the wii and take a look, mine had a piece of paper in it and it sometimes stopped discs coming out.

well most likely an overheat try looking at the manuals if not contact nintendo

The noise is the wii working extra hard to read the disk the lens might be dirty. Your wii might also have a bomb in it.............Just kidding. I would try cleaning the inside and if all is bad send it in to get fixed

Hello my name is Tim Ehrhart, I repair 360's and have had this problem with them and there problem is that the magnet that holds the disk in place gets stuck and makes a grinding noise that sounds horrid. Please leave feedback as I am new and trying to build a great rep. Thank You.

Seems like the wii froze. Try other discs and if worse comes to worse send the wii to nintendo

take it back to game

I think thats normal. If your really annoyed about it, Play some music that cancels out the noise. I'm sure the in-game music your playing should go over the buzzing noise.

I heard something on youtube about that. It seems that the disc is hitting on the case so you would have to take it apart and fix it.
