[QUOTE="pigoo3, post: 1569053, member: 56379"] Yes I realize that.:) I was mostly replying to your original question/statement regarding "best online repair service".:) Yes...it does sound like you have a hardware (logic board) issue. Since via a lot of parts swapping on your part (nice job):)...you seem to have proven that all of the ram is good...and both ram riser cards are good. I really don't think that there is any way to get that upper riser card to work...since it's the upper riser card slot on the logic board that seems to be bad. One thing I will mention...have you tried an NVRAM/PRAM reset? If not...never know...give it a try. [url=http://support.apple.com/kb/ht1379]About NVRAM and PRAM[/url] If the NVRAM/PRAM reset doesn't work...then installing a replacement working logic board would seem to be the best & least expensive solution. Like you already discovered...these can be VERY expensive (80% of the computers total value)...and many times really not worth it financially. But if you can a cheap one ($200) that works 100%...this would seem like the way to go. I wanted to verify one thing...to make sure I understand things correctly. Are you saying that you have gotten the computer to recognize 8gig of installed ram...by having 4 x 2gig ram modules installed on the one riser card? Thanks, - Nick [/QUOTE]
