When you want to buy a new PC: Looking at your current specs can help you figure out what you need in a new computer. This will give potential buyers the info they need to make an informed decision, and it will also help you figure out how much you should charge. When you’re selling your PC: When selling your computer, list all its specs together. Here are a few examples of when it would be good to know how to check your RAM, your CPU, and your other computer specs: Understanding the hardware inside your PC can help you with a number of tasks and in a variety of situations.

The same goes for downloading or creating new files. If you don’t have enough, you won’t be able to install it. Whenever you’re installing a new program, it’ll tell you how much space in the hard drive it needs. Since it’s a piece of hardware, the motherboard has certain physical limits - for example, if your motherboard has only two RAM slots, you won’t be able to install more than two RAM modules if you’re upgrading your RAM.

Your CPU, GPU, and RAM all connect to the motherboard, which lets them communicate with one another.

The more RAM you have, the more your computer can handle - the more tasks it can process - at once. Your computer uses RAM (random access memory) to juggle all its active tasks at any given moment. Just like your CPU, your GPU can also overheat if you give it more than it can handle. Knowing your GPU specs is especially important for gaming and other graphics-intensive tasks like video editing. Your GPU (or graphics processing unit) handles everything you see on your screen. An overworked CPU can easily overheat, so it’s good to monitor your CPU temperature, especially when putting it under heavy stress. Many programs need a CPU with a minimum level of processing power, so you’ll want to know exactly what your computer can handle. The CPU (central processing unit) is your computer’s brain.
