Windows 7: Coprocessor - Device not installed

12 May 2009   #1

Windows 7 Build 6801 x64
Coprocessor - Device not installed

I can`t figure out what driver I`m missing. When I open up device manager the only thing Im missing is "coprocessor"

The drivers for this device are not installed. (Code 28)
To find a driver for this device, click Update Driver.
If I click update driver, or do windows update to see if that brings up anything... nothing new is found.

Any Ideas what it could be?
My Laptop is HP Pavillion DV2913CL

Coprocessor is a part of NVIDIA chipset drivers. I had to force the driver from the .inf to install on a friend's HP laptop.
There's only once confusing bit...the driver is not actually called Coprocessor when manually loading it, it's named something else which I can't remember...
I was actually surprised when it loaded fine and windows accepted it...
I was basically stuck exactly where you are, coudn't find any online Win7 related info, however the search did suggest that Coprocessor is indeed part of NVIDIA chipset drivers.

I then decided to simply take a shot at force loading stuff that made sense from the .inf's....

A couple were rejected...and one worked

...can't think of the name tho...


EDITED: Mistake corrected. I meant NVIDIA chipset drivers not AMD!

Windows 7 Build 6801 x64

On the HP Drivers site the only thing I can't install is:

- Conexant High-Definition SmartAudio 221 Driver
- Conexant HDAUDIO Soft Data Fax Modem with SmartCP Driver

I'm not sure if they are supposed to go on here or not, but both always give me an error when I try to install them. That might be it then? I wouldnt think they had anything to do with the AMD Chipset...

Win7 Pro

I run into the "coprocessor" issue as well. My laptop model is HP DV2419US, nvidia GeForce Go 6150 / nForce 430/410... Win7 provides the video driver, but I don't see the chipset driver. I've visited the NVIDIA website to download but I can't find it. Please help!
