iMac (late 2009) won’t turn on and here is how it works:[br]

When I plug the cord one green LED turns on, second LED never appears[br]
Before cleaned out RAM contacts with alcohol when I pressed power button I heard fans and hard disk sounds but no screen and no boot chime.
After I cleaned and reinstalled RAM fans run only when memory sticks weren’t installed (sometimes it run and shut down randomly) and when I have memory sticks in it fans doesn’t run, actually I hear how they try to run for a second.
What can be damaged? Power supply? Logicboard? and what it has to do with RAM? or maybe memory itself is the reason?
