i know there are a lot of threads related to old G3 iMacs, but since each one is unique I don't feel to guilty starting a new one, especially as I have browsed other threads and none of them solve my problem:
I have a Flower Power iMac i got off eBay. Was for spares and repairs, and I put in an old iMac HDD in, and a stick of RAM. I replaced the battery, pressed that button thing, tested the voltage using a voltometer (all fine BTW). Now when I press the 'on' switch the light does not come on HOWEVER, he small green light on the logic board does. Plus there is a bit of whirring, not like a hard drive, but more like a helicoptor. I reckon it is one of the boards, but am really stumped. Anyone any the wiser on this one than me?
Many thanks in advance.
