[QUOTE="pigoo3, post: 1747942, member: 56379"] The bottom line here is: - If the replacement logic board is good. Then something else is busted. - If the replacement logic board is bad. Then the replacement logic board is bad...and you need a good one. Problem is...you really don't have a reliable way of knowing if the replacement logic board is good or bad. Since it sounds like too much time has passed since the replacement logic board was purchased & installed....to be able to return it. The only additional thing I can suggest is. Do a complete erase & reformat of the HD...and a fresh install of the OS. If the problems remain...this confirms that the problem is hardware & not software. And right now the #1 hardware problem has to be the logic board. Especially since it cannot be confirmed if the replacement logic board is good or bad. - Nick [/QUOTE]
