The usual way I diagnose computer problems is by substituting known working
parts for what may or may not be working. To do this, you need to have some
extra parts lying around. If the Deskpro motherboard and power supply are
standard sized, then you can substitute parts easily.

At this point, the system may not be powering up because any one of the power
supply, motherboard, processor, or memory could have failed. Memory failures
are generally pretty rare. Processor failures are even more rare, especially if
nothing else has failed.

If you can find a friendly and inexpensive computer repair place, that may be
the quickest way to a working computer, as long as Compaq spare parts are
available. But I would not spend more than $50 on the computer, and someone
else may even consider that to be too much... Ben Myers

Hi there!

I just got a pretty old Compaq Deskpro config, really nothing special,
approxx 1,3 GHz, 128 RAM, everything else integrated, and with a small
HDD.

the box wasn'tg opened, so the computer was untouched for like five
years.

i tried to turn it on, but nothing happened...
the led on the mainbord is on, so the power supply is OK (I tried
another one too...)

the cables leading to the turn on button seem to be OK too, cuz i
tried to connect the jumpers manually, and still nothing happened.

i don't know what the problem is, the PC is too old for a complaint;
and I really dont know what know.

i mean can i fix it somehow? probably not, but i'm courious, maybe i
didn't try everything...
