I have just noticed in the device manager of my new PC, under 'other devices', something called 'coprocessor' is listed with following status: '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.' I have tried to update driver automatically- no luck. What is the coprocessor and does anyone know which driver I need or where to try and what to search for?My system:AMD Athlon 7750 Dual- Core processor (2.70 GHZ)4 gig RAMWindows 7 x64 Home PremiumNvidia Geforce 8200ASRock K10N78FullHD- hsli motherboardThe PC originally came without OS and included an ASRock 'AMD- nVIDIA series support CD- Rom'- user manual, drivers, utilities. I have tried the disc, which does contain drivers when browsed but it wont auto install them.
Any advice appreciated, cheers. Jobeard you are indeed correct but, 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.I spent a lot of time in research on this. My goal here is to save someone the frustration of correcting this problem.Cheers,J. Hi,I have lurked around these forums for a while now and I felt that I must register to say thankyou.@ Greeble1 I have an onboard Geforce 8200 and a 9800 GTX.
I've never succeeded in disabling the 8200 and as a result i've had lots of problems, black screen when alt tabbing, black screen when going to task manager, what look like driver related crashes (pink screen, blue screen and one that looks like the screen has shattered) and of course the coprocessor problem. I downloaded the driver pack that you suggested and as yet I have had none of the above problems.So I thankyou for your time and advice:grinthumb.
The Nvidia ION chipset was used in affordable Intel Atom based Nettop PC’s released in 2009 onwards. Although not very powerful compared to PC’s of the time Nvidia ION based Nettop PC’s such as the Acer Revo R3600 series and the AsRock ION 330 where very popular for playing HD video. Using XBMC 720p and 1080p HD video decoding could be offloaded from the Intel Atom processor to the Nvidia ION GPU, allowing 1080p High Definition video to played back with ease on a very low powered device.If you want to install a more modern version of Windows on an Intel Atom / Nvidia ION based desktop that is perfectly possible.
