Can't detect my GPU

Hello guys,

 

I've been brought here by trouble regarding my Nvidia GPU. Two days ago, I was prompted to install a new driver for it (by the card's own program, as usual). I accepted, and launched the installation. At first, it told me that Steam was preventing it from installing, and asked me if I'd like to shut it down and install again. I clicked yes, but Steam didn't exit, and the driver was starting to install, so I exited Steam manually.

 

After this I had to leave the PC for a bit, but when I returned it had restarted, claiming that 'a problem caused an unexpected shutdown' etc.

 

Since then, I tried playing a few games but noted very poor performance. I instantly thought of the driver again and checked out my Nvidia software. The hitch: My card is completely undetectable. I have tried re-downloading the driver, only for it to find no Nvidia GPU itself. My computer has switched to using the integrated graphics (hence the terrible performance in games) and this is all that shows up in Windows Devices. In Nvidia GeForce Experience, there's just a blank space everywhere my card model is supposed to be listed.

 

So, do you think this is something you can help me with? Thank you in advance for your time and effort.

 

PC model: Lenovo Ideapad Z500

OS: Windows 8

GPU: NVIDIA GeForce GT635M

Can you go into device manager and rollback the driver.

I can't, because the GPU isn't even on the list of devices any more, as I said in the OP.

Whats the device its showing under display adapter right now? This is a laptop right?

Because the ideapad comes with integrated Intel® HD Graphics 4000.

 

Or did you replace the video.

 

Heres the drivers for The laptop:

Believe it or not, a simple BIOS update appears to have fixed it. Thanks a lot for the help, Roodo.

Hmm, okay, looks like this problem is back with a vengeance, this time for no reason (wasn't installing the update or anything).

 

Because of this happening again, I'm pretty sure now that I somehow messed things up with my driver updates.

 

Could anybody with an Nvidia GPU lend a hand? Looking at my files, outside of Program Files I have an NVIDIA folder with seemingly two updates in the 'DisplayDriver' folder (331.82 and 332.21). I'm thinking I may have ended up with untidied leftovers from previous versions after a driver update. Any advice please? :(

Download an older version of the driver from the nvidia archive, when you install the software do the "clean install" method. This should remove the new driver components. If the device is completely gone from device manager, I might suspect you have a physical hardware problem. Even if the driver is a problem, the hardware should appear in device manager. It is possible there is an issue with windows. You could try booting into a linux distro, something like parted magic, linux mint, or anything you prefer and see if the hardware profile sees the nvidia gpu.


If I am helping you with a problem and I have not responded within 48 hours please send me a PM.
