What could cause only fans running when powering on?

I replaced the hard drive in an iMac g4. Powered on with chime several times. Before I could get the OS loaded it froze up so I powered off to restart the process. When I powered back on only the fans are running. No chime, No screen, No DVD drive working. The red light under the first panel is on. I hit the PMU button but still nothing. I replaced the 3.6V battery underneath also. Could it be the power supply unit (even tho the fans turn on) or is it something with the mother board?

Had you tried reseating the memory RAM / test with another known good one?


No I haven't. Would that cause it to not do anything? I don't have another one on hand. It was working and booting up fine. Then nothing. Had plugged in a USB to try to load from when it froze up. Not sure that could have done anything tho.
