I booted up my AIO G3 today and heard breaking glass. It was working fine Friday. I shut it down and now it boots up with a normal chime that warbles and there is no video signal. The screen is black. I removed the hard drive and reseated the ram. It will not boot from a CD. The symptoms are the same. Could it be the motherboard?
