[QUOTE="pigoo3, post: 1496973, member: 56379"] When we do our own computer repairs...the best we can do is eliminate as much as possible...and then see what we are left with. In this case...if the logic board were bad...I don't think that the computer would startup. If this were a laptop computer (with integrated graphics hardware)...it might be a different issue (could have a "bad" logic board/bad graphics & still start up). But since your PM G5 has a video card that is removable/replaceable...this is the only other truely end-user "testable" hardware. Which then leaves the power supply as the problem. But no guarantees.;) - Nick p.s. FYI...the basic Apple hardware test that comes on the gray DVD...is not always 100% accurate...but better than nothing.;) [/QUOTE]
