Do you have monitors connected to each of the display connectors (motherboard, VGA and DVI and HDMI on the add-in video-card?  Do any of them show anything when you power-on the computer?

Remove the video-card, and enter BIOS SETUP. Does it show an option to give "preference" to the onboard video, or to any video-card connected to a PCI-E connector? Change the value. Exit from BIOS SETUP.

Power-off. Insert the video-card. (Does the video-card require an additional power-connector?)

Connect the monitor to a port on the video-card. Power on. What happens?

Hi, yes monitor is connect fine and displays a picture, if I remove the card everything works as it should, I've also tested the card in another system and it works fine, power connecters are plugged in. the bios is very basic with no option to change prefered gpu setting. I've tried disabling the on board graphics and also tried to boot in safe mode, none of this has worked unfortunately

I was hoping that you would have monitors simultaneously connected to both the "onboard" video-port and to a video-port on the add-in graphics card.

There's only a slight difference between "preferred GPU" and "onboard graphics".

Hi,

I think you have a BIOS problem.

The 760 requires a UEFI BIOS. You have a Legacy BIOS (7.xx).

Check downloads for your PC to see if HP offers a BIOS update to a 8.xx BIOS when using W10.
