Dead MVS

I've had my machine for a while now, but this afternoon when I switched games the system did not turn on. No noises, no nothing. Then when I unplugged the unit the grounding pin came out and was stuck in my electrical socket. What should I do? Replace the powersupply?

Any help would be great, and I've already spent a fair bit at Hard Mvs but it doesn't list what happens when the system goes dead.

Thanks in advance.

Man what a bad day.......................................

Check for a Blown Fuse...in the cab or in the power supply.

Hopefully that's the case. Will check later today.
