Wiiconnect24 overheating and damaging Wii GPU

[Darkfire55]

Sorry to be somewhat off topic but I need some advice.
So, I am experiencing this problem and there are yellow dots on my screen.
How should I fix this?:
1) Send my Wii to nintendo to get it fixed.
OR
2)Exchange my Wii at toys r' us for a new one. (My Wii is covered under a 2 year waranty)
