Seems this post has got off topic a little.

Look, I am in Tassie now and whilst not a noob, and no way an expert either. So my best efforts said power board and was happy to spend the $100 on the board.  Now the machine did not boot up at all.  Nothing, No lights on the CPU board. The new board has got that all working fine, but the game reset has my skills a little baffled where to go looking after i tested the coil diodes, replaced a few i was unsure of, plus one that was broken in the ball trough switch.

But I still have game resets. Being in Tas, I opted for the new board without knowing the claim they are a little dodgy. Had some good opinions from others on the pinscore boards so went with it. I do think having my old board overhauled and put back in to see if the problem is removed is not a bad option also.  Will try some of the advice on the weekend and if no luck will go the old board rebuild option.  There are just so many things that could be causing the game reset it feels like it is getting outside of my skill set and being in Tas I don't know anyone whom could pop round to help out. Was not an issue when living in SEQ. Any Tasmanians on here????

Thanks for the advice. I tend to think everyone is right. Refurb old board is probably best bet, but did think the new power board which claims to reduce heat etc etc might have been a good option so went with it. But the laugh may have been on my bank balance but I put that down to lack of having the necessary skills and knowledge.
