My Wii isn't wanting to function (read desc.)

RECOMMEND HEADPHONES IN, AND VOL UP (so you can hear stuff that's a part of the issue.)

I know this may never be answered but,,,whoop. So my wii has been acting up, it reads the wii disks (was an initial issue I've fixed) and shows the game. Then I click onto the Start button- then it goes through the white screen with all the instructions for your controller set-up. Then...its stops. The wii stops reading the disc, and it causes an error. I'm not sure what to do, the disc I have inserted is not damaged, scratched, or messed up in any way so why is it randomly stopping mid-way?

Note- LISTEN CAREFULLY. You will hear the Wii trying to read the disc (and it does.) Around the end I scoot closer to the Wii to show you that it runs- and then stops, showing the error message.
