Laptop (64 bits) with Nvidia 8200M graphics needs coprocessor driver

Hi, Dev man shows yellow triangle vs Coprocessor driver after clean install Win 10 x64 + Nvidia driver via automatic update.

Now the 32 bits Win 10 (upgrade) was no problem- the coprocessor driver was installed. But not when I try a clean x64 install.

I recall this kind of problem years ago (and it's not an uncommon one on HP blog), and the solution was to search for a driver by directing the update search to the extracted HP driver in C:swsetup. But I don't have that folder now.

Trying to update the driver or use GEForce Experience is not helpful.
There is no appropriate 64bit graphics driver on the HP site.

(I haven't noticed a functional problem despite the missing driver, but I'm not pushing the graphics at all).

Is there a way to solve this by manually installing the Nvidia driver?

Thanks!

I had a similar problem with a Compaq (HP) CQ50-105NR.

The driver is for the nVidia motherboard chipset, rather than the graphics device.

I had to download the Window 7 drivers, extract them, and update the co-processor driver from within Device Manager.

I couldn't find a link to the drivers at HP. Maybe because I'm on an Android tablet at the moment.

Believe it or not, I downloaded DriverMax, a driver scanner, and the coprocessor driver was the first result!

I'd tried downloading a couple of Nvidia drivers and unpacking them, but no joy.

I believe that the notebook has an nVidia nForce chipset to support the AMD CPU. I see o chipset drivers for the G60 214EM at HP, though.

That seems odd. They have Windows 7 chipset drivers for my CQ50-105NR. I suppose that you could try those, if you could verify that the chipsets are the same.

Hi, thanks, there are, but the HP site is limited for this PC.
Vista: NVIDIA nForce Chipset Driver 17.07 A 23.1 MB Aug 7, 2015
Win 7: NVIDIA nForce Chipset Driver Version:15.46 Rev. A Aug 07, 2015

& I think these are only 32 bit.

Anyway, DriverMax's download eliminated the yellow triangle in dev. mgr, so I presume must be good..

I've never tried a driver update utility, but I'm glad that DriverMax helped you.

A quick online check indicates that DriverMax is safe, and doesn't install any PuPs (potentially unwanted programs). It may try to sell you the paid version, but that's not overly annoying.

Thanks, I'm familiar with it- and would not now countenance turning to one in any but exceptional circumstances, as this one was. Just surprised it provided the solution- the coprocessor driver missing has been a common issue for many on this laptop in changing OS's.
