Hi,

I was running a geforce 760 GPU perfectly. runs everything on ultra. its was great until it need to update drivers so i did and the sound stopped. so i reverted drive back and when i restarted nothing came up on the screen. plugged it onto the onboard graphic (I7 quad) using HDMI cable and it didnt work. when the GPU not in it works but if its in nothing displays on either port.

ive uninstalled all nvidia stuff on the PC and then plugged it on so it could reload default basic drivers, didn't work. cant install drivers off the website as you need it plugged in but cant plug it in as neither work when it is. frustrating as im a IT technician and cant get my own PC to work! found similar problems but not exact like this. really appreciate any help.

All the Best

When a PCI/PCIe GPU is detected by the BIOS, any integrated GPU is automatically disabled unless you set the BIOS to allow both to work simultaneously (a feature which is only available on specific motherboards). So that part of your post is not actually a problem, it's normal behaviour. To use integrated GPU, therefore, you must remove the PCI/PCIe GPU, which is what you did. All okay so far.

What isn't okay is the fact that your 760 appears to be faulty if it's sending no video signal out at any stage of the boot process. That's not a driver issue. If it was, only Windows would be affected inasmuch as it (Windows) would have to use it's own basic, low-res driver.

I set the bios to boot to the onboard graphics only and loaded up the drivers from there, then reset the bios back to the card and it now works. cant believe i didn't think of it before but your post got me on the right tracks. thanks!
