GTX 770 - Windows Not Recognising my GPU?!

At the moment I'm unable to use my GPU because Windows doesn't seem to recognise that it's connected.

This is all I see in my device manager...

The problem occurred this morning as well, but I was able to fix it by connecting my monitor to my on-board graphics and then reinstalling my Nvidia graphics drivers. When I try run GeForce Experience now, this is the result I get.

Any help would be greatly appreciated.
 
first off I would turn off the PC and re seat the GPU in to the PCI-E slot and make sure all power cables are connected to it. If possible maybe try another PCI-E slot if you have a SLI motherboard.

take it your using windows 10?

Yes, I'm using Windows 10. I was about to try uninstalling Nvidia drivers using the Guru3D display driver uninstaller (DDU), but after restarting into safe mode upon the program's suggestion, I was unable to see any picture at all, regardless of whether I connected to the on-board graphics or the GPU itself. I've connected using different VGA cable now and for some reason I'm getting a picture now, however, I'm limited to a maximum of 1280x1024 resolution, despite not yet having uninstalled any drivers. I will continue to uninstall, then reinstall the drivers, then I will do as you suggested. Thanks.
 
that's fair enough, run through DDU and re install, I got the same ress in safe mode when I got my new gpu.

hope it fixes the issue.

So I've run DDU, although when it listed the detected drivers, it only listed my integrated Intel graphics and some other... Windows... Something-or-other. No Nvidia. Is this normal? And is there a site I can go to download drivers directly, rather than relying on GeForce Experience to download and install things properly?
 
Never mind. I'd already downloaded the driver from Nvidia's site this morning when this problem initially occurred (I fixed it by reinstalling drivers - much simpler than this bs) so I just used that .exe and it seems to have worked. It installed all the bits and pieces of the 361.43 driver flawlessly. Hopefully it won't go **** up after the next restart.

Thanks for your help!
 
Well it's happened again this morning. For some reason my GPU isn't listed in device manager and Windows automatically uses on the on-board graphics.
 
Seems strange but could there be some kind of clash between the onboard and your gpu?

I'd disable the intel gpu in the bios and make sure the bios is also set to use a pci card as primary. Worth a try anyway!
 
First thing I tried this morning was to try booting intonsafe mode to use DDU again, but since booting into safe mode I haven't been able to get a picture of any kind, regardless of whether I connect to my GPU or motherboard! I can't even see the boot screens.

Safe mode only boots windows using a bare minimum amount of drivers, if there is some kind of weird hardware clash, it wont make a difference. Try the bios!
 
After booting into safe mode I was unable to see anything at all, even after several reboots. I tried booting into my BIOS but even then I couldn't see anything either. I've just restarted my PC after trying to enter the BIOS and now for no apparent reason it's giving me a picture again! Shall I run the risk and try booting into the BIOS again?

Also for some reason it's limiting my resolution to 1280x1024. As my monitor is currently connected to my GPU, not the on-board graphics, device manager only lists 'Microsoft Basic Display Adapter' as the sole display adapter. No mention of on-board graphics or my 770.

I changed the default graphics to the PCIe in my BIOS. Still got a picture, still limited to 1280x1024. I strongly suspect this is a software issue, but could it be a BIOS problem?

To me it stands to reason that if by previously uninstalling and reinstalling drivers fixed the issue - even temporarily - it sounds like some sort of software issue, not a BIOS problem. Initially I was worried it might be hardware, but again, its my understanding that would be unaffected by changes in driver software.

If you believe its a software issue, can you not try the card in a different pc? or try it after a fresh windows install? You could even try creating a bootable usb stick with Ubuntu on as you can boot from the usb stick to test without installing or changing anything on your hdd. I do this occasionally when testing hardware.

I'd double check the card is seated properly and connected correctly to your psu.

Took the card out, cleaned out some dust, put it back in, same ****. Windows still identifies the one single display adapter, the 'Microsoft Basic Display Adapter'. I hate doing this.

I have no other PC available and I will need to find a working ISO of Windows to download before formatting my PC. I'll download Ubuntu and try test my GPU that way; is there any particular you'd suggest for testing the card in Ubuntu? I have very little Linux experience.
 
To be honest, I just wondered if the card functioned properly, i.e let you change your resolution higher than the 1280x1024 you are being limited to and was correctly recognised with no issues. if so then you are probably right about the issue being a software one and a fresh install of windows would hopefully fix your issue.
 
After MANY annoying and time-consuming hiccups along the way, I managed to reinstall Windows 7 and everything seems to be working correctly for now.

Thanks for the support. (:
 
Upon booting up my PC this morning, again, I got no picture. I restarted and still no signal. After the second restart I got a picture and everything seems fine. Since then I've restarted once through Windows, however I've not shut down the PC yet.

Could it be that I there's some confusion in my computer's BIOS? I did previously change change the default graphics output in my BIOS to use the PCIe slot, so I'm pretty sure it's not that.

I just want to add that I'm pretty certain this isn't an issue with my GPU, as I'm able to play video games and watch high-resolution video without any problems. To me this smacks of a firmware/software, possibly even a monitor problem, but I'm hoping someone with a better understanding could enlighten me.
