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 ?
