Graphics My GPU seems to have disappeared

When I turned my PC on this morning my monitor didn't show anything and only displayed when I switched to using the iGPU on my motherboard, via HDMI. I've been into device manager and my GPU (a HD7970) isn't there. I've been into my boot menu and my GPU settings are set to 'auto-detect', and I've also installed the latest version of CCC just to see if that would help, but nope...

Any suggestions as to things I could try?

Specs:

Mobo: Asus IV Gene-Z (G3)
CPU: i5 2500k
GPU: AMD HD7970
Ram: 8GB 1600Hz Ripjaws
SSD: Crucial M4
OS: W7

 

is it powering up? fans spinning etc?

 

Yeah the fan's definitely spinning, and what's weird is I've not made any significant changes to software or hardware for a while. It was working fine just yesterday.

 

Hi Kissenger,

Can you try a different connection to the gpu, DVI maybe? Might also be worth trying to reseat the card in the pci-e slot just to rule that out.

 

Also check your BIOS settings to make sure it detects external GPU first.

 

I thought about doing this, but what would I do if it doesn't work?

 

Thanks Matt, but I'm afraid that hasn't worked. Just cleaned out and reseated and no luck.

 

Do you have any other computers at home you could test on?

 

Could you try switching pci-e cables too, just to rule that out?

Below would be the next thing I'd try.

 

I've just tried switching over. Still nothing on the display, still nothing in Device Manager. Unfortunately I don't have a second PC to test it out in.

 

Have you tried a different PCIe slot ? (if there is one)

 

That might be an idea. I assumed my board didn't have a 2nd PCIe slot because it's micro-ATX but I just checked the Asus site and it says it's got 2.

I'll report back later. I sort of hope that it doesn't work though, because at least the card is still in warranty

 

Let us know how you get on.

 

Well I tried the other PCIe slot and... it worked!

Which is sort of good and sort of bad. I suppose it's safe to say the GPU works (if it works it one PCIe and not the other, surely it has to be the PCIe that's busted, right?), but now I'll have to RMA my motherboard.

Asus' warranty is 3 years, right? If so, I have exactly 3 days to get it back to Scan/Asus

Edit: just out of interest, does anyone know if I will get worse performance using the 2nd PCIe slot on this board? Underneath the 2nd slot is printed 'x8' in big letters, but the Asus page for the board says they're both x16.

 

they will be both x16 probably, but if both were populated the second one would become x8, if my thinking is correct

 

At least you discovered what the problem is. If you raise the rma immediately then you should be ok. Or you could just keep using the second slot. If you've no plans to add a second card, that's what I'd do most likely. It should run at x16 as long as the first slot is not occupied.
