Unknown device problems occur due to several reasons, and one of the most common reason is missing device drivers such as when the ‘Coprocessor Driver Is Not Installed.’ When the drivers are not installed, the coprocessor device will be marked with a yellow warning symbol or a question mark in the Device Manager, and its properties will provide the description of error code 28.
Since a coprocessor is an important PC component, which aids the CPU to enhance system performance and functionality, it is very important to fix coprocessor troubles quickly. Considering the functions of a coprocessor device, we will discuss some methods to install the missing coprocessor drivers. These methods will work for any PC and laptop models (Dell, Acer, HP, Ienovo, Compaq, et al) powered by Windows OS such as Windows XP, Vista, and Windows 7.

Updating the chipset drivers or a system device driver like the coprocessor driver may turn out to be a very frustrating task. An example of that is when a PC user tries updating or installing coprocessor drivers on a computer, but the coprocessor unknown device is still listed in the Device Manager. If you have been going through the same coprocessor trouble, then the online Knowledge Base articles of Driver Detective will be very useful for you. They will provide an extra guidance for fixing chipset and coprocessor driver installation problems.
You can also try installing the missing coprocessor drivers manually. One way is through the Device Manager, which requires your chipset installation CD or a backup CD. If you don’t have a backup CD, you can try to download drivers manually online, but as mentioned, it may require lots of time and energy. After downloading the chipset drivers, you can try to install it by following these steps:
a. Go to your Device Manager
b. Right-click the coprocessor device
c. Click Update Driver
d. Specify the location of your download drivers
e. After it has been located, follow the provided on-screen instructions for installing the chipset drivers
In case that the coprocessor device is still listed as a problematic hardware device in Device Manager, you should consider using Driver Detective. If you get stuck, you can contact their free online support or employ their online Knowledge Base article discussing the process of Chipset Driver Installation.
The most common reason why a coprocessor driver is not installed is when the chipset drivers you installed on your computer are outdated. Also, if you’ve just upgraded your OS from XP to Windows 7 or from Vista to Windows 7, the coprocessor driver for Windows 7 may be missing completely.
It can also be due to incompatibility issues. These happen when the current backup copy of chipset drivers is not compatible with your newly installed OS. So, if you’re going to download drivers manually, you must check your OS type, whether it’s Windows XP, Vista, Windows 7, et al, and either it’s 32-bit or 64 bit OS. Then you must download drivers compatible with your OS in order to prevent coprocessor unknown device problems and additional PC troubles such as computer hang ups, freezing, and Blue Screen of Death (BSoD.)
So, if you have experienced a problem where a coprocessor driver is not installed, you can try to reinstall the chipset drivers or install an updated version of chipset drivers. You can do this manually or you can use Driver Detective, which will save your time and energy compared to undergoing a manual driver search and download.
