Coprocessor Driver Not Found
Apr 2, 2009
I installed Windows 7 Beta Build 7000 (from official windows site, but i got a windows key from a friend of mine ^^) a couple of months ago, its all working fine.I recently installed the Windows 7 drivers available at Nvidia.com for my Nvidia 9500GT and got a noticable FPS boost.Today when I was just browsing some stuff i noticed that I had 2 driver errors:
USB Camera <-- old thing, bought it years ago, so screw that xD
Coprocessor <-- No further information given O.o
so I tried to use the troubleshoot thing by rightclicking on my computer (with the yellow sign next to it ) and clicked Troubleshoot. It tried to reinstall the coprocessors drivers, but couldn't find earlier drivers so it failed.so now is my question: What the hell is my coprocessor? Could it be the onboard Nvidia geforce 7050? I personally doubt it becouse when installing Windows 7 it showed it had downloaded the WMD drivers from windows update for the 7050 and the 9500...

I have an AMD Phenom II X3 710 2,5 GhZ, and after fiddling around some in the device manager I notice that the "coprocessor" is unknown, and I can't find drivers for it.I've an nVidia 8200 chipset with plans on changing to AMD 890GX/SB850.As a sidenote I'd actually also like to hear the experience of you wise fellows if any has tried changing motherboard without reinstalling windows.

Location: PCI bus 0, device 1, function 3 .
The drivers for this device are not installed. (Code 28)
There is no driver selected for the device information set or element.
To find a driver for this device, click Update Driver.
The above is found in my Device Manager under "Other Devices" "coprocessors" . I have already tried to install drivers for my sound card (Win 7 drivers are available)but when I do , Im told they dont need to be updated, I have the latest edition. I assumed the coprocessor was my sound card because I dont have any sound. Im tempted to do a system restore ! My m/b is a MSI K9N2 Diamond.

I have an AMD athlon 64 x2 dual-core TK-53 processor but i can't find an driver for the coprocessor not even on the offical site. Windows say's in the device manager that it isn't working properly because there are no drivers installed.
I am getting this message... The drivers for this device are not installed. (Code 28)
This is resulting in my laptop in crashing regularly and windows tries to recover the display driver.
I have a HP dv6525 with 7150M / nForce 630m - driver version 7.15.11.7948.
Running Win 7 Pro x32 bit.

Got this MSI CR600 Core 2 Duo laptop today with 32bit Windows 7. Promptly installed an RC version of 64bit Windows 7 on drive D which enables me to boot in either version.
Downloaded Nvidia's laptop motherboard driver which got the sound and Video going. Performance Test rates this machine at 689.6 which is not bad. Only problem in Device Manger is an exclamation mark against "Coprocessor".
Any ideas on where to get the driver for this "Corprocessor?". Windows update did not help.

I've tried installing the Win7Vista 179.48 32bit beta drivers from nvidia and have had no luck. I've even installed them in Vista Compatibility mode. The only drivers available for Windows 7 at the HP support site are wireless drivers, and I've tried using older drivers supplied by them for Vista with no luck there either.

I am running an HP dv2810us 14" laptop with the GeForce 7150M / nForce 630M video/chipset.
I have read a few posts regarding this issue across the internet. Been searching out this bugger for weeks now and the closest I have come to resolving it is this site.
I am running a 32bit version of 7 and the coprocessor driver will just not load.
I have downloaded my drivers from HP, Nvidia, and guru3d. Multiple sets of each and none of these will work.
I have used universal extractor to pull apart hose files to get at the inf's and can't get it to work. I saw two references to this solution being fixed.
first guy said he loaded a driver out of HP's set and it worked but he could not remember which one and that it did not seem like it was the right thing
second was a jc guy from this site that said he did it by getting drivers for a different laptop from HP which he also did not say which.

Okay so, my laptop's system is unable to boot, so I just tried to format it since I have to do that for a very long time, and when it asked me in which partition I want to install windows there was nothing, although when I clicked "Load Driver" I could access the hard disk's files, the hard disk IS listed in the bios normally but windows does not recognize it, I tried using Kaspersky Rescue disk(the only CD I had along with the recovery disk)and when I used the File Manager, the hard disk still didn't show, are there any drivers I have to install?I have burned both fujitsu9that's my laptop) and Seagate's websites and can't find anything, I have searched forums but the only answers were "check if your hd is listen in bios".So, i IS listed in bios but I can't reinstall windows nor access it

I have an HP DV6500 with an AMD TL-64 processor and the NVidea GeForce 8400M GS graphics card. It's the rs085av model.
I recently installed Windows 7 Pro 32 bit, and I managed to install all the drivers except for two items. It shows "Coprocessor" and "Unknown Device" as incorrectly installed. I don't know what the Unknown device is, but it might be my cd drive (slimtype DVD A DS8A1P ATA), which also isn't working. Also not working is my Ethernet port, which is on the motherboard.
So, if anyone knows what drivers I need to grab to get those to work, or if I need to reinstall the chipset, I would love to know.

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.

As I was exploring my Aspire 7530g I stumbled upon an uninstalled component, the "coprocessor".
Device Status:
"The drivers for this device are not installed. (Code 28).."
I did my research and found a mass variety of solutions.
I opened Everest and saught out the unit myself.
nVIDIA MCP77 - Management Unit
I asked my good friend google for some drivers and how to's.
I downloaded and installed the latest drivers to my Nvidia 9400m.
Alas, the effort led me to the same climax of me having an uninstalled CoProcessor.
Am I supposed to install M-board drivers, suggestions?

I recently did a clean install of windows 7 home premium (64 bit) on my notebook Hp Pavallion Dv6700z CTO. It came from Hp with Vista home premium (64 bit) installed. My processor is an AMD Turion 64 x2 Mobile technology TL-60 2.0 GHz (amd lists this as a dual core). It has 2.0 Gb ram w/ 64 bit OS. I am getting an error message which states...
Coprocessor-The drivers for this device are not installed. (Code 28). I tried to have windows resolve the issue but it could not locate any drivers.I tried Microsoft support but after almost 2 hours and many driver installs they say they cant find a solution and its Hp's fault for not supplying drivers. I went through Hp they but its my problem because they dont support any OS updates so any help would be apprecited.

I am missing three drivers in my device manager. They are listed under other drivers and when I look at the properties there is no information given as to what its for.The first two say base system device and the third one says coprocessor. None of them can be updated from the manager because it cannot find the drivers online. I believe the first two have to do with nvidea but everytime I try to download the driver it does not work. I have no idea if I am even on the right path. This is the last issue I am having from my windows 7

I just got a brand new computer for christmas, it's a hp compaq dc5850, and it was working fine until now! I tried turning the computer on and it got stuck at the blue hp invent screen, I didn't know what to do, so I finally decided to just try and restore it. When I try to use the windows 7 disc to do this it keeps saying "no drives were found. Click to load driver to provide a mass storage driver for installation".

Ok, I'm wanting to go from Vista 32-bit to 7 64-bit. I ran the upgrade adviser and it said my Linksys wireless adapter needed action taken. I went to linksys website, but only found the 32-bit driver, and I'm guessing that won't work on 64-bit, right? I have the WMP54G ver 4.1 if anyone can help me out.
