Windows 7 - Other Devices - Coprocessor

[Fuzzi0n]

I've noticed this before in the device manager, but never really worried about it. Now it's just gnawing at me. Anyway idea what this is? And where to find a driver? Oh, I'm using an Acer Aspire M1640.

Hi and welcome

Co processor is a term to indicate a math co processor. A thow back to older terminology. Is it "unknown" (has a yellow triangle on it)? If you want to check its status you can right click the device and go to properties. If installed coreectly it will say working properly.

Yeah it has a yellow triangle on it, I knew there was no driver installed for it for a while, well when I first installed 7. First place I went to the device manager.

Anyway, it says "The drivers for this device are not installed. (Code 28)
" And when I update the driver says driver not found or whatever.

Hav you tried the Intel chipset drivers?

Intel® 5500/5520/3400 Chipset Driver for Windows*

Just tried it and it gave me the error "The component doesn't meet the requirements for this software".

Can you right click the Coprocessor (in device manager) -> properties -> details tab -> choose hardware ids from the drop down list -> paste the output here

Here you go.

It appears that you may have an nForce chipset...the vendor is NVIDIA but I can't find the string of that device listed for them (unless no one has reported it...)

The closet...a 07DC ended up being a nForce 7 chipset...so lets give it a try and install a nForce chipset driver

x64: NVIDIA DRIVERS 15.51 WHQL
x86: NVIDIA DRIVERS 15.51 WHQL

Yeah the SMU driver did it. Oh and btw, do you have any tips for finding drivers for my computer for xp. GPU is no problem but the rest, not so much.

Did the driver I provided work? Thats fantastic!

As for your XP drivers...it will be a challenge...we have the GPU, chipset, and possibly the Audio drivers covered...but nothing else

If you look at Acer's website...they give you nothing for XP Acer Support - Drivers & Download

I am glad you are dropping the search for the XP drivers...there are pretty much none out there for your model

I have the same problem. I bought my HP Pavilion dv6813nr in 2008 with WIN Vista ))) Now I installed Windows 7 32bit. I have GeForce 7150M/ nForce 630M. What driver should I try to make my Co processor works. Please, Help me

Go to the link it will auto detect the coprocessor and download the drivers. The drivers take ages to load so be patient.
