So, I have a G4 933 quicksilver running the new leopard software.  The other day my computer just shut off.  When I try to turn it back on the light on the on switch turns on for a second and then shuts off.  The fans don’t power up, the screen does not turn on and the hard drive does not try and spin up.  Just wondering if anyone new what my problem could be.  I am thinking that it is the power supply but they are a little expensive so I don’t want to buy one if that is not the problem.  This is my secondary computer so I am trying to fix it for as cheap as possible, I would like to not send it in to get serviced.

Thanks for any help
