Hi I am new to Mac, I just bought a G5 I Mac off eBay. It's supposed to have Leopard installed. When I turn it on a white screen with the Apple symbol and the timer circle comes on but that's as far as it gets. When I start it again holding the option key down the screen with 3 icons comes up. The first icon is a arrow going in a circle the middle one is a hard drive icon with a gray X on it, the third one is a right arrow. I can't click on any of the icons. A clock is on the far left side. When the clock runs for a bit it goes back to the white screen. Thanks Don
