Coprocessor error code 28
After installing the new drivers from Nvidia (195.62, 197.16 and then 258.19) I still have the drivers for this device and are not installed (code 28) error. I have tried to uninstall the driver and re-boot the machine and windows finds the hardware and I get the same error.
When I updated the driver, I download the driver file, go into the extracted directory and run the setup.exe file. Then I go to the device manager and update the driver for this device and specify the directory for it to search on my hard drive.
I have a GeForce 8400M GS video card and am running Windows 7 Ultimate 64-bit. My laptop is an HP dv9500z (Product GP347AV). I am running an AMD Turion 64 X2 2.2 GHz processor.
Can anyone help?
