If you put a new power supply board into the machine then i doubt it's going to be the problem , i've heard the Pinscore ones are ok
Also if you have a multi meter just check the voltages coming out of the new power supply board to make sure it has a good 5 volts.
Check all the connector plugs going to the power supply to be sure they are good , especially the large 12 pin square one as it sometimes burns.
Also check that the CN17 connector on the Cpu board is on properly , wouldn't hurt to check all connectors.
You could also have a good visual check of all the switches on the machine for any broken diodes or that the switch isn't shorting against something it shouldn't be.

The Pinscore's I've seen and used have been great. Unless we can isolate your new PSU as being faulty I don't see any value in paying to have the faulty one repaired.
As I suggested on AA, you need to check the diodes on the COILS. Switch diodes can cause wacky behavior on the switch matrix, but generally not a reset.
If its the shooter lane coil which causes the reset, then I'd look there first. Check to make sure the diode has not cracked or broken away from the coil. Next test the actual Ohms of the coil too.
As Ken (the board guru) suggested have a good look at CN1 & CN2 connectors and the pins. If the pins or connectors look burnt, then these can cause resets too.
Also check the fuse holders on the PPB board. Unlikely but check it for cold solder joints as well. On my D.E games I generally push the fuse gently. If the fuse clip gives way, its well past its bedtime!
See how you go with these first. I reckon we should be able to help you through it without having to pay more money for repairs.
