To determine if the math coprocessor installed in your computer is faulty, follow these steps:

1. Open System in Control Panel
2. Select the Device Manager tab
3. Double-click System Devices, and then double-click Numeric data processor
4. Click the Settings tab
5. The following message is displayed in the Diagnostics box:

    

   • Your computer's numeric data processor has passed all diagnostic tests and appears to be working properly

     or

      

   • The numeric processor in this computer can sometimes compute inaccurate results when dividing large numbers

    

It's obvious that if you get the second message, you have a faulty Math Coprocessor. In that case you can switch of the use of the Math Coprocessor, by selecting the Never use numeric data processor on the same Settings tab.
