Sure here goes

Unplug the molex to mobo wires Tried This didn't work

Do 1 gpu. Use the pcie riser closest to the CPU see if it works just 1 gpu. Tried this didn't work

Install all drivers and get it mining. Just the one card.Tried This didn't work

If that does not work install one gpu in the full slot.doesn't work even in the full 16x slot

Fully install drivers and get it mining.


Other tricks what are your gpus.

Do they have a dvi connector .  If so buy a dvi to hdmi connector. DVI didn't work

Many times. Dvi to hdmi works.

The cables are cheap.

If the gpus only have hdmi out along with display out ports use a display to hdmi cable as sometimes that works.

I have hdmi to display
Hdmi to dvi
Display to dvi

And they get past a lot of connection issues.

Three adapters are all under 10 bucks.

Does your display have dvi and hdmi?

Cheers for the help though!
