Co processor driver missing

[damon86]

i have recently done a full system clean and upgraded from win 7 x64 home prem to win 7 ultimate x64, since doing this i cant find my co processor driver. will this make any difference to my pc, and how can i find it. checked all drivers on my hard disk, and all windows up dates are done,
i am running an acer (aspire) ax3400, windows 7 ultimate x64, 1tb hdd, and 6gb ddr3 ram, with an amd athlon 64 425 triple core, can anyone help?

Install the chipset from the Acer Support Downloads webpage for your model.

Hi damon86, Just reinstall your motherboard chipset driver (get them from the Acer website ,they will be newer drivers )

Ok thanks i will try that in the morning. Its been a long day. What is a co processor and will it make any difference to my system in any way?

Oh and i had a look. On acer and they list my x3400 but have no frivers and the tower is different. They list an x3400g where they have drivers and tower is the same. Should i try the x3400g drivers?

Make sure you are on the Downloads website for Europe which may show different models for downloads. http://support.acer-euro.com/drivers/downloads.html

When I google ax3400 drivers it shows it is a US model which Downloads page is here: http://www.acer.fr/ac/en/US/content/drivers

I also see the x3400 as the only choice when I choose Aspire desktops. I would input the Serial Number to get more accurate results. Acer has shoddy organization of their downloads.

I have been on acer typed serial number and downloaded the chipset for my pc and correct version of windows but will not let me install what so ever. Any ideas?

What is the error given when it refuses to install?

After downloading the file, rightclick to extract the files from the installer package then rightclick Setup (Application) to run as Administrator.

If you can extract the files take note of the location and then in Device Manager from the Co-Processor device choose Update tab, then Update Driver, then Browse to the location where the file is unzipped to see if it will pick up the driver.

Hi damon86, the coprocessor used to do the math on the old 8086 processors ( the floating point) nowadays it is no longer required to that extent as we have multicore processors capable of doing it , have a look here What is coprocessor

Post #7 here,

What is the Coprocessor and what driver is needed? - TechSpot Forums

is about the best explanation of what it is in this case.

in this case, it was not a coprocessor but a flaw between the Win 7 sub-system and the lack of a specific Nvidia driver. The hardware ID pointed to part of the chipset. I am not sure why this did not show up in other OS's on the same computer (such as Vista and XP) but it seems to be a fairly common problem for Win 7, more specifically a Nvidia problem as opposed to MS or AMD.
