did you try your graphics card on other PC
try to clear cmos by jumper on the mother board or unplug power cable then remove battery for 5 minutes to clear cmos
I will try your recommendation first thing today.
No, I dont have another PC to try it in.
The reason I believe it is the socket is because the brand new one does not work either.
Side note: the internal graphic card built into MB does work via VGA.
I'll let you know.
