anyone have an idea of why 8500 its dead. I recapped it as a precaution. I did my 9500, and many other Macs. The 8500 has no signs of life. I don't have the original video card, but everything else was original. I have tried pulling all cards, pressing cuda while turning counter clockwise singing kumbyeya, new battery etc. can't believe it is dead. I checked over my caps, all look good. any ideas?
