I got an iMac G5 2.0Ghz (ALS) from a friend which doesn't boot.

When I push the power-on button the front light turns on, and the fan starts spinning. I don't hear the happy mac sound though.

After a while the fan starts spinning very hard. All this time the screen doesn't turn on.

I've opened the back and here a look at the interior:

The caps are not bulged and don't appear faulty. When inserting the power cord led 1 turns on, pushing the power button makes led 2 turn on. Led 3 and 4 don't turn on.

What do you think? The person who gave it to me said a computer supplier took a look at it and concluded PSU was broken, but since led 1 turns on I don't think that's the case is it? I know the caps are often faulty on this iMac, but here they appear fine. I know looks can be decieving though.
