Hey Team, I have an older G5 (bought 2004), dual 2.7, liquid cooled. It no longer boots. It powers up but then nothing happens bar fans spinning. I can hear that it looks for CD, or something with the CD rom drives happens. I have removed ram, Hd and video card and plugged them all back in again (there was a video card issue that was resolved with it being reseated previously). Visually all is well, no leaks, no burns, nothing weird going on. I have a newer quad 2.5 G5 which I can steal parts off for testing although the video card is different as i tried that already..... Are there any common faults that I should be checking - I am hoping for a quick fix as it's not worth much but want to sell as part of a starter kit with some recording studio bits I am selling. Any help much appreciated.
