We have an old Dell 2400 "extra" computer with no video. The root cause was leaving it plugged up during a lightening storm. At first it was completely dead but now it will power up and I can hear everything working but there is no video.
I put in a used mother board and it does the same thing, no video, the orange light stays lit on the monitor. When I unplug the VGA video cable from the computer the monitor light turns green.
I have a feeling this is the RAM but no way to test it and don't want to spend more money. It has to be the PSU, RAM, or perhaps the on/off button.
EDIT: oh yeah, I forgot to add, and I did try a PCI video card and it did the same thing
Any suggestions are welcomed and thank you.
