4 Slot Reset/Flickering HELP!!

My 4 Slot has started to reset itself about 10 seconds into a game, once it resets it just starts "flickering" as if its trying to start up again but won't anybody know what this could be??

I have tried Various combinations of games and even single games in each slot and the problem just persists.

Anyone?

Check the +5v line. If it is too low, it can cause the issue you mentioned.
