How to Troubleshoot Logic Board

テキスト:

I changed my power supply twice. One green LED lit even after Power button is pressed. I unplugged power button from logic board and ohm'ed the button. OL at rest and 1.8 ohms when depressed. Momentary switch, button is good. How can I test the logic board or can it even be tested? Or do I have to change parts until it works?

Really need help with this, can't afford to change parts hoping it will work.
