There are several reasons to find out what your computer's specifications are. You may need to know what hardware you have when you are troubleshooting an issue, or you may need to know what's "under the hood" when you are buying or selling a computer. If you are buying a new monitor you may need to determine if your graphics card can work with the monitor you wish to buy. You may also want to know the specs just so you are knowledgeable about what is in your computer. The Windows operating system comes with a utility that will tell you the specs of your computer.
