Whats is Wrong with My Nintendo Wii?

when i start up the usb loader to get to my list of games it won't load and a black screen comes on with 'stack dump' and all these numbers like the matrix screensaver, what the hell is goin on, can somebody please help me.

Suggestion:

try plugging in your hard drive into the other usb port
make sure the hard drive is formatted to wbfs or try a different loader like wiiflow or coverfloader
