Discover the Hardware in Your Windows 7 PC
To begin exploring the hardware in your PC, click on Start and then click on Run. If you don’t have the Run command on your Start Menu, hold down the Windows key on your keyboard and hit R. Either method will bring up the Windows 7 Run dialog box.
In the Run dialog box, type in MSINFO32. Note that this command is the same whether you are running a 32-bit or 64-bit version of Windows 7. Also, this command works with all flavors of Windows 7 (Home Premium, Professional, Ultimate, etc.). Now, click OK.
You should now be looking at the Windows 7 System Information Window. This window tells you just about everything you would ever need to know about the hardware in your PC. Notice that you can see what motherboard, CPU, and memory you have inside your computer.
However, the System Information window will only report the hardware that Windows 7 recognizes and knows is working properly. If you want a more comprehensive look at every component in your PC, you should use Device Manager.
