If you put the reset button on the power pins and it worked, then you 1) found the right pins, and 2) have a bad power button/wiring. Any chance this is the excuse you need to buy a new case? If not, just leave it like that and use the reset button.
If your like me, you might never power the machine down. You might want to use the mobo power button on the few times you need to, and leave the reset button as a reset button. Up to you.
