I recently formatted my computer and keep windows xp. However, when I got to the Device Manager to see if anything was missing, I saw a yellow exclamation mark next to "Video Controller (VGA Compatible)" and Multimedia audio controller. I don't have the CD for the drivers but the computer works just fine.

A Driver is software that interfaces your operating system with the computer's hardware. Every hardware device has a driver.

If a drive is missing the hardware will not function as expected to check if your missing drivers in windows.

in XP

Right click on my computer select properties, then go to the hardware tab and select device manager, if any of the devices in device manager show up with a yellow question mark you are missing the drivers for that hardware.

in Windows 7


Right click on computer select manage, and then device manager on the left in the new window that opens. Again if there are any yellow question marks you are missing drivers.

So if your missing a driver what do you do?

well if you bought your computer from a major manufacturer such as dell, hp etc all your systems drivers can be found on their respective websites.

usually they have a support section to their websites where you can enter your computers model number and search for downloads and information once you find the appropriate driver download and install it, and your hardware should be behaving normally now.

If however your computer is not from a major manufacturer, once you have determined what device is missing a driver from the device manager you need to find who made that device. This is usually done by opening up the computer and looking for a label on the device of some kind. Then you need to go to that manufacturers website and see if you can find the driver.
