I would ring Rob from Bikecity and the first thing i would say would be "listen prick, I am not asking you, I am telling you, fix my machine, or I will come down there AND"
(well u get the story !) 

p.s -
 I would make sure the game roms are sitting in tightly.
I had a game resetting the other day, pushed on the roms, and the loose one seated properly, and then I had no more resets.
