[SOLVED] Graphics cards not being detected by pc

[sanicwowguy]

Hey all.
So my graphics card (gtx 750ti) us not appearing in the device manager, despite it being fully in the pci-e slot and the PCI/PEG being enabled in the Asus bios. I know that it is not the motherboard that is faulty because i used it in my old build, along with my gtx 770. Any help would be appreciated. Many thanks.

Is the gpu also set as primary in the bios? Not just enabled.
Have more pcie slots to test in?
What motherboard and cpu are you using?

 

[sanicwowguy]

The motherboard is an ASUS P8H67-m pro, and the cpu is the i5 2400.
The case is too small (matx) to accommodate the gpu in the 2nd slot.
How do I set it as primary in the BIOS?

and the PCI/PEG being enabled in the Asus bios. I

Try to set this to PEG/IGPU ,see if it helps.

You btw have the latest bios? "Version 3904 from 2013/07/23"

 

[sanicwowguy]

Setting it to PEG/IGPU does not resolve the problem, and when I try to update it to version 3904 via ASUS ez flash, it says that "selected BIOS is not an EFI bios!" How am I to circumvent this?

The usb stick was clean? Is it formatted in fat32?
The bios file extracted/unpacked from the zip file.

I had that problem recently when upgrading to gtx 970 and what solved it for me what simply installet the proper drivers from nvida website. Have you installed drivers for the card after switching?

 

[sanicwowguy]

So after much looking at, I have concluded that it is the graphics card that is defective. Thanks for your efforts on trying to help on this situation.

Might well be,only testing with another can say for sure,but guess you tried that.

Why not keep using the gtx 770? Or already sold ... maybe also broken?

 

[sanicwowguy]

The 770 is being used in my current build. The build I was addressing is a build i built for family use.

On my win 8.1 the gpu does not show in DEVICES.

Click icon on desktop:

This PC > Properties > Device Manager

And there you'll see a bunch of stuff. Your gpu will be under video or something like that. If you click on it it will drop down to the specific device and if you right click on the device there is a driver install option. (installing drivers through Windows is frowned upon in these fora, but the option is there)

But if I just search on devices in either win 8.1 or win 10 I get things like the screen, the mouse, etc., But no GPU.

So try the "This PC" route and see if your gpu shows up.
