No standby LED and no power when turned on

If the caps are bulged out on the top, then they are bad. I usually replace all nine of them just to be on the safe side. Also, you might want to check your 5vdc standby voltage while it is still hooked to the main board. I have ran across a few with no standby light that is caused from a short (which I can't seem to find) on the main board. The voltage always reads 2.8vdc instead of 5vdc on these. Hope this helps.
