Hi, I'm wondering if perhaps the graphics card you're trying may not be
compatible? Have you tried another one to see if there's any difference?
Has it got onboard graphics? If so, and you're using a card, is there a way
of disabling it in the bios? (If so, that may be the problem)
If theres still no difference, I would try disconnecting everything else, to
see how far it gets.
If all seems well, connect everything one at a time to try to troubleshoot,
restarting each time.
Hopefully, this might help.
