Dell Optiplexs (3) Will Not Power Up After Ensuring the Power Supplies Work

Over the last 2 days I have been hit with 3 different trouble tickets all relating to the same thing. These Dell Optiplexes won't power up. I have tested all three with a working power supply (actually with the one I am using to type this question).

No fan
No lights
No nothing, except
one of them shows the Nic light on even though the PC won't power up. I don't have a voltage meter.

Thx,
matt

Does it power up now?

Tried it on all three machines. No Go.

I have taken of three apart and there is a light on the MB for all of them.

One way to diagnose the MB issue to take all the components off, right and see if it still does not power up.

Thx

Two of the MD have leaking capacitors. :-( Guess they are shot.

The third looks good.

I will strip everything down and let ya know what I find.

Correction all three have capacitors that are leaking. Guess all move on the next problem.

Thx for you suggestions.

contact Dell as they may be part of a bad batch and they will replace them free of charge (its happened to me in the past )
