While playing games the wii makes a high pitched sound

Have you recently upgraded your firmware?

Your Wii isn't working anymore. I would recommend you to buy the Wii mini, since it's cheaper than the normal one.

try checking the router firewall settings, and lowering/disabling them

Same Problem.. I have wii softmod. Never had any problems, except the black ops loading screen freeze, which I fixed.. Now, when I play multiplayer, team deathmatch, it freezes with a loud buzzing sound in mid battle.. Some 1 help please!!!

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.

it does that main is brand new and it does the same it noting

un plug it and re plug it

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

by eating a grundle

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