So I'm upgrading my girlfriends pc from a 760 and putting my old 1070 in it. I went ahead and uninstalled the old nvidia drivers and took the old card out and put the new one in. After that I hooked everything back up but now when I turn the pc on it can't get a video signal from the gpu. The lights and all come on and the fan spins like it should but just no video. What all can I do to try and fix this problem??

PC Specs:

i7 4770k
MSI z87-G43 Gaming Motherboard
RAM 16gb of hyper ddr3
750w Gold Corsair PSU

Your graphics card should be compatible with those components if that is what you are asking.

You can try resetting the BIOS to the defaults. You can clear the CMOS if you have difficulty entering the BIOS.

I had problems with a GTX 970 installation once. It just wouldn't update. Every time it would restart after updating the driver, and the system would black-screen when Windows started to load. I know my way around a PC, and it had me pulling my hair out.

But if you keep at it, it usually works out. And if all else fails, reinstalling Windows does help (when you have GPU recognition problems.

Make sure that the graphics card works on another system. That way you can isolate the problem to the driver. You can also try...

Check the device manager/display adapter for your graphics card. If the "generic display adapter " is listed, it is having problems recognizing your graphics card.

If so you will need to update the graphics driver. Updating the driver from display adapter menu using a downloaded driver in a specific file location (that you can browse for specifically) can help.

Reinstall of the operating system is a worst case option.

You may try another slot. Make sure that any additional power cables are connected. Check for LED's on the graphics card.

The trick with browsing for the updated driver location helps. I download the drivers and unzip the driver onto a thumb drive. It makes it easy to find the driver.

And sometimes it takes reinstalling the operating system to finally get the driver updated. Graphics drivers can sometimes be a real pain. Other times they update easily.

Make sure that the graphics card works on another system. That way you can isolate the problem to the driver. You can also try forcing the BIOS to look for the graphics in the PCI Express x 16 slot instead of auto (that can cause problems if you need to use the integrated graphics, but clearing the CMOS should reset things back to the defaults).

I just kind of gave up on it. I put the 760 back it and it works no problem so who knows. I appreciate the help.
