Hey guys, I was wondering if you could help me with a B&W PowerMac G3 that I own. For some strange reason at the moment it won't boot up. It switches on and I heard the "bong" but that is as far as it goes. There is no video on the screen but the machine is still running. I've tried resetting the pram however i only hear one "bong" which makes me believe it hasn't been reset correctly. I'm not sure whether this is the battery is dead or the graphics card. Any ideas?
