Hi, I have a Wii that displays these weird dots during games and channels, and after looking around, I've known it is the GPU overheating problem. Thing is, I have a modded Wii, and I didn't solder it myself; what should I do to get a replacement from Nintendo? I've heard that replacing DVD drives between two Wiis work but I want this to be confirmed, and if it is possible, can someone post me a link to do it step-by-step?
