It's possible for a logic board fault. I see White ones for less than a logic board so I think I'd get one of those to move my HDD and RAM over to.

13 inch Macbook mid 2007 white. When problem started I researched causes which pointed to hard drive or hard drive connector cable. The following was done:
1. Obtained a USB hard drive enclosure and installed the lap tops hard drive and plugged into the laptops usb port. Was able to boot from the drive through the laptops usb port and all seemed normal. Based on this I believe the hard drive is ok.
2. Obtained a new connector cable 922-7579 hard drive to logic board & installed. Boot up attempts question mark still remains.
It seem something might be wrong with the logic board. Anyone have any experience, ideas, suggestions?
Thanks
