PC manufacturers are able to sell computers for low prices by contracting with companies to buy computer hardware such as hard drives, RAM and processors. So it is extremely rare for all your computer components to come from the same manufacturer. Most companies use separate contractors for everything. If you need to diagnose a problem or replace a component, you may need to find out the manufacturer's name and the model number of the part.
Decide whether you want to find out the name and model of your motherboard without opening up your computer. Sometimes, opening the case of your computer may void your warranty. Sometimes, the model number is not printed on your motherboard in an easy-to-read form.
Check the documentation that came with your computer. Most of the time, the company that sold you your computer will list all the components inside. If your concern is that you didn't get the motherboard you paid for, you will have to resort to other means to double-check.
Open your case and take a good look at your motherboard. You may want to use a magnifying glass because everything in your computer is very small. Look between the expansion slots where expansion cards typically go. These slots are a few inches long with metal teeth inside. Many times, the model number and maker are printed between the slots. Check near your processor. If necessary, remove the motherboard to ensure the information is not being blocked by a cable or expansion card.
Identify your motherboard by checking the BIOS. Each motherboard has a BIOS that tells it how to operate, and these are generally unique. You will see your BIOS on setup or can get it through your Control Panel settings. Websites such as Wimsbios will check your BIOS for you over the Internet.
Contact the manufacturer of your PC if all else fails. The information may be listed on the manufacturer's website. Contact a customer service representative with your question; they should be able to refer to your records and determine the hardware in your computer.
