Keyboard problems

I'm having keyboard problems. Everytime I turn on Maple Story my keyboard stops working. It wont respond to anything. It happened yesterday and I finally plugged it into another USB port, but today when I tried to log in, it broke that USB port too. Now it doesn't work in any of the USB ports. I have Windows Vista. Has anyone else had this problem? If so, how did you fix it?

Oh, and this just started happening yesterday, and I've been playing Maple Story for about a week now. And the computer is brand new.

EDIT: So my keyboard is working again. It just started working on its own a few hours later. But I still want some pointers on how to fix this, because it's bound to happen again. Any help would be greatly appreciated.

 

try a different keyboard.
