I just got a A1145, MA064LL/A G5 powerPC 2.1Ghz that I am trying to fix. It freezes on the light blue screen with the mouse cursor in the upper left corner. The mouse is moveable. It will not boot from CD (same error). It will not recognize external HD via Firewire. It is not in the model range with bulging capacitors (and there aren't any) I have taken out the HD and ran TechTools diagnostics on it and it passed I tried wiping the HD The battery on the Logic board is over 3V I did the SMU reset All 3 diagnostic LEDs light up on the logic board I reseated the Memory I weird notation to make is that the owner swears that he had Snow Leopard 10.6 installed and running on here for about a year with no problems. I read that the powerPC's can't run OSX 10.6. I have verified the serial number. Any ideas? Thanks.
