Hello I have a Imac g5 1gb of ram 500gb hdd its the 17inch model it has the dvd burner in it. it's not the isight model. I'm new to mac just trying to get this thing up and running. I replaced the pram battery I reset the pram. I have a windows wireless keyboard and mouse that I got finally working. when I turn imac on it goes to a grey apple screen then blue then to a language menu. Then it starts loading firewall internet and printer connections which takes forever then after that it goes to a screen that I can pick systems prefences or quit. Either one I pick does nothing can someone please help
