I have an iBook g4 14" 1.42 ghz. I recently installed a new hard drive. I put the install CD in. Then, I pressed the power button, then the "C" key. Black screen and No chiming. Please tell me, what I can do to resolve this? What is the problem with it?

A hard drive replacement on a G4 iBook as well as many others may suffer some small detail error on reassembly. You should consider going through the disassembly like before and make sure all connections are firm and that there are no loose wires. Also try to reset PRAM and PMU.

Since it will not boot then a hardware test can't be run. You could try FireWire Target Disk Mode and if it works then access from another Mac to run tests on the new drive. You could also try installing the OS X software from the host computer. If this does not work then professional help should be considered.
