Windows 7: The device driver for Coprocessor has not been installed.

Windows 7 64 bit Home Premium
The device driver for Coprocessor has not been installed.


I know this issue has been brought up a lot but I've tried all the options in the other threads and it hasn't helped.

I am running Windows 7 64 bit Home Premium on a system that was built for Vista. I have the GeForce 9100M G graphics card. I did a Resource and Performance Monitor report after having a blue screen issue and my gadgets stopped working, and the following was reported:


Symptom: Device drivers are not installed.
Cause: A driver has not been installed for this device preventing it from working properly.
Details: The device driver for Coprocessor has not been installed. This device will not be available until the correct device driver is installed.
Resolution: 1. Try installing the drivers using Windows Update.
2. Install the drivers that are on the installation media that came with the device.
3. Check with the manufacturer for an updated driver.

I re-downloaded the current driver from Nvidia's website with a clean install but that didn't help.

Does anyone have any other suggestions?

angelangelina04 welcome to the Seven Forums.

You don't say who made your laptop (the M in the video card model gives it away), but check the download page for your laptop at the manufacturer's website for the chipset driver.

Sorry I forgot to say it was Acer. I tried putting everything needed and left out one of the most important details! Anyway, I did get it fixed. Thanks for your help.
