@ BigJerr,
So based upon what I have read you have tried all of the display ports on you computer. The motherboard vga and dvi ports and your graphics card vga and dvi ports.
(DVI ports are the ones you are calling serial)
If this is the case I would check your ram next.
How many ram sticks are installed in the desktop computer?
* Be sure your ram sticks are seated firmly in the ram slots
* If you have more than one memory stick try pulling out one at a time and try booting after each ram stick is pulled.
* Using only one memory stick try to boot with the memory in different slots.
Please take note of the original memory configuration before pulling ram
EDIT: I think Compton already suggested this but I want to make sure it was done correctly by the OP
