Answer» I have a windows xp desktop, givin to me, it was DOA, replaced motherboard,new memory stick. Power up the machine, fans all run, green light is lit on motherboard. I cannot seem to get it to START and give me a screen to work with. A red light is on, on the front of the machine, green light does not come on. How do i by a process of elimination find the problem? If i plug in the cd rom drive the lights come on but cant open the door unless i disconnect the grey ribbon cable then it opens. Assuming that the memory is compatible with the motherboard, you only have the power supply and the processor left. Replace the cheaper item first. If the PC now works, you got lucky. If it doesn't, and you then buy the other item, by now you have a new PC in an old case. I hope it wasn't a Dell, and you put a non-Dell motherboard in there? I replaced the motherboard with the same exact model that was in it. No it was not a Dell. I now have another Hard drive coming. If the power supply was bad, what would the symptoms be.

That only accounts for 2 voltages (fans are +12VDC, green light is +5V, Standby).
