I got a desktop that was custom built, wasn't turning on, i changed the power supply and the ram, that did not fix it,
so i changed the motherboard, now it does turn on , the fans are on, and the hard drive making noise, but no video output to the screen at all , not even on the POST.

i changed the graphic card, the ram, the power supply. (on the new mother board).
and still same issue,
what else is it possible ?

You can try installing the graphics card on a different slot if possible, other than that the only thing that ain't change is the monitor itself.

The monitor is working on my other desktop.
And untried a new pci graphic card on the two available pic slots (after the built in graphic card didn't work)

Are you using the same video cable on both PC's with that monitor?  If not, make sure you take the same video cable that is working and try it on the other machine.

i suggest to use the minimum setup for troubleshooting, as described in my article :

It could be. You say the monitor does not turn on, but the hard drive does?
do the fans spin when you power on?

does it make a system beep when you power on?
