Re: Dead Computer - Power Supply or Motherboard?

P.S.: By dead, I mean completely dead - nothing happens (no lights, no
fans, no drives running, etc).

Be aware that some Dell PCs do not use the standard ATX pinout/color code,
especially older models.

Thanks.
Since I have an old Dell, with its "infamous" non standard connectors, I may
have to wait on this though.

Don't take this the wrong way but have you checked the fuse in the plug.
Also does it have an output to run to a monitor as well as you could probably
pick up a lead for pennies if you do not already have one

You could try to borrow another power supply to test most PSU are either 20
or 24 pins. Borrow one could save you money, but if no lights or fans come
one, I think your going in the right direction and should probably get a new
PSU
