I was trying to use the flashchat on my wii browser, then my wii froze, I tried pressing the power button, that didn't work, then I tried the reset button, that didn't work, So I decided to "Pull the plug"(Unplug it)

I waited 30 secs. before pluging it back in, when I pluged it back up, It wouldnt turn on X_X...
then finally after 30 mins it began to work again..

Is there a possibility something could be wrong with my Wii?
