Hello, I got gifted a quadra 840av but it will only boot after several tries but then works fine... I've replaced the capacitors and bought a new p-ram battery but it didn't seem to make any difference... the board looks like it is in great condition no corrosion on the traces... Does anyone know whats going on with this machine? Could it be the power supply? I've noticed I get better chances of booting when I let it run for a few minutes and then turn it of and on very quickly..
