Flashing folder icon with question mark.
Imac shows the folder icon with the flashing question mark. I inserted my install CD and held down the C key and nothing. It keeps coming back to the folder icon with the flashing question mark. Lights 1, 2, & 3 are lit up. I can connect it to my MacBook Pro and put the iMac G5 into target disc mode and I am unable to read the hard drive on the G5. My MacBook Pro can see the install CD on the iMac G5 but it does not see the hard drive on the iMac G5. It appears to be the Logic board and I would like a 2nd opinion. Thanks.
