Hi Put some new ram in my friends G5 last weekend, worked fine for a week and now it won't boot into osx. It gets to the white loading screen and the little spinning loader just spins for ages and ages. apparently she had it on for an hour and it still wouldn't boot in to osx. Is it the RAM if it worked ok for a whole week? I talked her through the procedure for removing the ram, so now she just has her original ram in there. But it still wont work, shes tried resetting the pram and also the pmu on the motherboard. The Apple discussion forums are down I think she might have kept all her ram in when she installed new firmware, could this cause a problem Can anyone suggest something?!
