Some computers are designed to use a dual core processor or a coprocessor to improve performance. A coprocessor is an additional chip designed to supplement the central processing unit (CPU) of the computer. Essentially, coprocessors give added speed and efficiency in the way the computer handles information.
On some occasions, non-standard video drivers loaded onto a computer can cause conflicts with the coprocessor, resulting in an error message. One visual indication of a problem with a corrupted driver, or a conflict between the BIOS and a driver, is the display of a yellow exclamation point next to a driver in Device Manager window. These conflicts can occur if you:
Install a retail copy of Windows Vista.HP does not recommend installing a retail copy of Windows Vista on computers that were either designed for Windows XP, or may not meet the advanced hardware capabilities of more powerful versions of Windows Vista.
Install a non-HP video driver.HP does not recommend downloading and installing drivers that are not tested and validated by HP. Installing non-supported drivers could cause unwanted problems such as intermittent, unexpected rebooting or crashing of the operating system.
- Install Windows XP Professional.
