[QUOTE="pigoo3, post: 1404706, member: 56379"] Here's the deal regarding the blinking lights & ram. This is probably the area to place the most effort. The blinking lights/LED's are there for a reason. You may have messed around with the ram...which is a good place to start...by pulling all the ram & testing the ram sticks & ram slots sequentially..but this may not have been enough (see explanations below). A couple warnings: - The ram in Powermac G5's must be installed in matching pairs. So you can never have less than two sticks of ram in there at any one time, they must be a matched pair, and they need to be in the appropriate slots. Thus...if these "rules" haven't been followed up until this point...this would be one place to start. 2. Also realize that some sellers (who may or may not know any better) may install ram into a Powermac G5 that was meant for a Windows computer...and thus MAY NOT be compatible with a Powermac G5. So...it's possible that SOME or ALL the ram is not compatible with a Powermac G5. Just mentioning these things as possibilities...since you're getting the blinking lights & it would be a shame if this Powermac G5 is not working...simply because it contains the wrong ram or incorrectly installed ram. - Nick [/QUOTE]
