Possible conflict between NVIDIA Driver 368.69 and latest Intel HD Graphics Driver

[FTent]

Hi Intel,

So I have a new laptop. Its a CLEVO laptop, and I noticed some incompatibility issues with the latest NVIDIA driver 368.69. I don't know if the problem is you driver, or the NVIDIA driver.

The problem happens as follows. Sometimes, when I open a program, and the Windows 10 UAC asks me if i'm sure that I want to execute the program, the time between the last click on the program icon and the pop-up of the UAC window, my mouse freezes. It stops, and then jumps to where it should be. This is an example.

Another example is when I click on the battery icon, on the bottom right of my screen, and wait for the battery info to be displayed, the same happens to my mouse. If I click on the battery icon and immediatly move the mouse, sometimes it freezes and jumps after a brief delay.

I've already done a clean installation of Windows 10, and I've noticed that when I was installing the laptop drivers one, by one, all was working fine and with no problems, until I've installed the NVIDIA driver 368.69. After that installation, the problem starts.

Moreover, if I only use the discrete GPU of my laptop (the NVIDIA one), the problem doesn't exists. It only happens when both graphics are working together.

I hope that you can understand my problem. If you need any more info, I will provide it to you.

System Specs:

Windows 10 Pro 64bit

Intel i7 6700HQ;

Intel HD Graphics 530 (latest driver installed it's the last beta that you provided, it also happens with the latest stable one);

Nvidia GTX 970M (NVIDIA controller 368.69, I will try to use an older controller and see If the problem persists);16GB DDR4;

240GB SSD;

Intel Dual Band AC 8260 (Yes, the problem also exists when I turn on and off my computer Bluetooth. I have the latest stable driver provided by you)

Please notice that this issue with my mouse, only happens when both graphics card are used together. If i disable the Intel 530, the problem doesn't happen anymore.

Hope you can help me,

Best Regards,

Filipe

Hi,

also i have a Desktop PC with i7-6700k and a nVidia GTX970 Card and Windows 7 Ultimate x64.

I have installed nvidia Driver v368.69 and Intel Driver v4474 and i have no conflict or any Problem.

Which Intel Driver have you installed ?

If you have Optional AntiVirus or Internet Security program, disbale it bevor you install a new GPU Driver.

My G-Data Internet Security has often Problem with Intel Driver and block some files !

Hi Pirilampus,

The issue seems to be a Hybrid graphics issue; I suggest you to keep using the customized drivers from Clevo manufacturer. Also, verify if you have the latest BIOS version and chipset driver. I igpu suggestion might solve the issue, give a try to it. Regards,Mike C

Hi there,

Thank you so much for your replies.

So no, i don't have any security program installed, yet.

And Clevo driver for the Intel GPU is the same that Intel has on his webpage.

So the problem should be an that Hybrid graphics issue indeed. And some incompatibility between drivers.

But, I have an another question.

My laptop cpu, an i7 6700HQ, does some electrical noise, like a bzzz bzzzz. This happens even when the laptop is IDLE or when is doing some work, like writing an email, the bzz bzz is clearly audible specially on a quiet room.

Is this noise normal? Should I be worried?

Thank you again

Hi Pirilampus,

This behavior is not normal, I suggest you to contact Clevo for pc maintenance or at least with your place of purchase. Mike C
