Question about Abit IC7-G Motherboard
Most obvious problem would be the power supply. The green LED only indicates that the 5V rails os working enough to power the on/off circuit on the motherboard. First disconnect everything except the mother board from power supply. Then try switching on again. If this does not work, then disconnect the power connectors from the motherboard. ON the big power connector (P1) there should be a green wire with two black wires either side. This is the power on sensor wire. Use a paper clip or similar bit if wire to short out the green wire with one of the black wires. This should start the power supply and the fan in the PSU should spin. If this does not work then the PSU is definately faulty. If it switches on when there is no load connected then it is probably only slightly faulty (not able to provide sufficient current). Since the green LED is coming on, my guess is that you have bad capacitors in the PSU (they will probably have domed tops instead of flat). Try a power supply from another PC if possible.
