hmmm are you sure the 24 pin cable is plugged in into the motherboard? from what i read you say this is a replacement motherboard and you say that you have tried your processor and ram on another computer and they are fine.

Well can you check if the power supply is not faulty?

looks like a PSU problem as greddy said.. there is a simple loopback test for PSU who dont have multimeter to check PSU. Get a paper clip(or any good conductor with similar dimensions) and insert one end to the green cable hole in the 24pin connector and the other end to any black cable hole. if the fan is not rotating, your PSU is not working..
