Flex 14 isn't detecting Nvidia graphics card

2014-03-28, 7:38 AM

Earlier today I booted up my computer and noticed the Nvidia control panel wasn't an option on the right click context menu. After going to services.msc, I noticed the Nvidia display driver service wasn't running, and if I tried to start it, it would immediately crash. I then went to device manager, and saw that under Display Adapters, the only visible one was Intel Integrated Graphics. I wiped the Nvidia drivers, and when I tried installing the latest ones I was told that "This graphics driver could not find compatible graphics hardware." I've already tried resetting BIOS, which did nothing. My concern here is that either the graphics card has died, or it has been shaken out of place somehow. Are there any suggestions you can offer to fix this, or will I have to take apart the laptop? Thanks for your help.

Specs: 

CPU: Intel (R) Core (TM) i5-4200U @ 1.60GHz (4 CPUs), ~2.3GHz

RAM: 4GB (4096 MB)

GPU: Intel Integrated Graphics (Onboard), Nvidia Geforce GT 720M (Discrete)

Model: Lenovo Flex 14

I've discovered the cause of the problem. A corrupt driver for "Intel(R) 8 Series PCI Express Root Port #5" was the culprit. In Device Manager, it appeared with an exclamation point on the icon, and after uninstalling the NVidia card showed up. After that, it was just a matter of reinstalling drivers and it was all sorted.

Hi AatishP97,

thanks for posting. If you go tothe BIOS is there an option for GPU? Within that setting is it set switchable or UMA only?

Hello NINE,

 

In the BIOS, my graphics setting is on "Optimus". I believe that this is the Nvidia feature that allows it to switch between both the integrated gpu and the discrete one, however it doesn't recognise the Nvidia card, meaning it is always using the integrated one, the Intel HD Graphics card. I think this is the equivalent of having it set to switchable.

The same issues was faced by me after updating to windows 10. After updating Laptop to windows 10 I installed graphics card driver and suddenly started freezing. I contacted lenova support care and nobody replied. Finally I started searching on Google and found this answer.  Thanks for the team for this answer.
