i know random pixels / green pixels = overheated or damaged GPU. after the wii rests overnight i can use it for a short period. it pretty bad and makes the wii unusable once the GPU gets warm. My wii is 14 months old. (out of warranty?) is there a way to alleviate this? add a heat sink to the GPU (is there enough room in the wii?) would one of those usb fans blow enough air into the wii to keep it cooler?
