how much guaranty does the wii have?

I bought my wii in january, im afraid if something happens to my wii with all of these problems going on

overheating and corrupted datachelosera91

Neither of those are problems. You are covered for 1 year and can extend it 3 months by registering your Wii at nintendo.com.

Put away the banner. This is a valid question.

And I'm glad only the people whose Wiis are overheating are posting about it. I wouldn't want to see the other 99% of threads saying "YAY MY WII DIDNT OVERHEAT EVER!!! R00X0r!!!"
