XPS 2720 Intel HD Graphics 4600 and Nvidia Geforce GT 750m

Hi ,

Thank you !you have tried most of the troubleshooting steps.It seems to me like a case of faulty system board .I would request you to forward the service tag of the system ,system owner's contact details ,invoice copy to confirm all the details including warranty active on the system to arrange for part replacement .

Hoping to hear from you soon .

Kindest Regards,

Hi,

Thanks for you response.

I think the warranty has expired.

But i think that it is not a material problem , because when i have run the 3 different tests with Dell Support Assist on the Nvidia video card :

2 tests do not show any activity on the Nvidia car (« short Test «  and « test under constrainst ») but the test called « test Nvidia Cuda » shows that the card is still alive and can work when the card is sollicited. I can see that with the software CPUID HW Monitor.

I think it is more an issue between the 2 drivers Intel and Nvidia and the share of the work / computation between these 2 cards for the applications or for the games.

Could you investigate and liaise as the case may be with Intel  and Nvidia to inform them ?

Best regards,

PS: where do i need to send the tag number or the service express number ?

UPDATE: I went back to nVidia driver version 350.12 and that seems to have fixed this issue.

I too have the same problem on my XPS 2720. It is fairly recent and apart from driver updates, I did have some windows updates that were installed recently. I still am not sure what is causing this issue but it is really annoying as I cannot run games or other 3D software properly as they are forced to used the Intel Graphics instead of nVidia. If you have made any progress or managed to solve this issue, please do let me know. Thanks.

Hi,

the previous driver of Nvidia version 350.12 does not change the problem. Th Nvidia Card is still not used by the Computer for games or 3d applications.

:(

I hope that the next versions of the two drivers (intel graphics and Nvidia ) will fix this bug.

Hi FXCG ,

Hi ,

I would ask you to confirm if you have tried using the steps mentioned in this link ,

Kind Regards ,

HI, it does not work.

Best regards

Hi,

It is a driver issue after the 350.12 version.

In fact, i have tried to reinstall the 350.12 after using the tool "Display Driver Unistaller", and then resinstall the 350.12 and now it works as before the Nvidia Card works again!
It is perhaps due to the Physx sofware ?

Any way the Display Driver Uninstaller (DDU) / Cleaner made for Display Drivers.(NVIDIA/AMD/INTEL) has worked for me.

Thanks

See the topic below of the Nvidia forum to find the tool to clean the computer before reinstalling the old version:
