How to find and check computer specifications in Windows 10, 8 and 7

Basic computer specifications

There is a lot of information you can find out about the components of your computer, but in most cases you will be interested in one of the main specifications listed below.

If you’re interested in a specific specification and want to quickly find out how to check the details, check out the section below.


The CPU (Central Processing Unit), or central processing unit, is the brain of your computer. For many programs it is necessary that the CPU has a minimum level of processing power, so it will be useful to have a clear understanding of what your computer’s potential is. An overloaded CPU can easily overheat, so it is a good idea to monitor the CPU’s temperature, particularly when subjected to heavy loads.


The Graphics Processing Unit (GPU), or graphics processing unit, handles the display on the screen. Knowing the GPU specs is especially important for gaming and other graphics-intensive tasks, such as video editing. Just like the CPU, the GPU can overheat if you put a heavier load than expected.


Your computer uses RAM (Random Access Memory), or random access memory, to juggle all the operations active at any given time. By increasing the available RAM, your computer will be able to manage and process multiple tasks at the same time.


CPU, GPU, and RAM are all connected to the motherboard, which allows communication between these components. As a hardware component, the motherboard has specific physical limitations, for example if there are only two RAM slots available in your motherboard and you decide to upgrade the RAM, you will not be able to install more than two modules.

Hard disk space

Each time you install a new program, the space required on your hard drive is indicated. If there is not enough space, you will not be able to complete the installation. The same goes for downloading or creating new files.

For what reasons can it be useful to check the specifications of the PC?

Having information about the hardware components in your PC can be useful for many tasks and in various situations. Here are some example cases where it might be convenient for you to know how to check your computer’s RAM, CPU, and other specs:

  • PC Selling: Before selling the computer you will be able to list all the specifications. This way, potential buyers will have all the information they need to make an informed decision. Furthermore, these data will be useful for you to establish the sale price.

  • Buying a new PC: If you know the specifications of your current computer, it will be easier to decide what features the new one should have. By identifying the gaps in the PC you already have, you can determine how powerful the new computer should be. If you plan to build your own computer, you can compare the specifications of various CPUs, as well as examine the benchmarks of different GPUs, to decide what you need.

  • Request for technical support: When contacting technical support for hardware or performance issues, be prepared to provide the relevant specifications. To offer proper advice, support personnel will need this information.

  • Driver update: If you want to update your graphics drivers or update your sound drivers, you will need to know the exact model number of your graphics card or sound card. Of course this applies if you don’t use an automated driver update tool.

    AVG Driver Updater detects hardware specifications and automatically keeps all drivers updated. The extremely intuitive interface of this tool will allow you to update outdated or faulty drivers, fix any persistent driver-related problems and quickly restore your computer to optimal performance.

  • Try new games or new apps: Do you have an older PC or laptop and want to try a freshly released game or even a classic like GTA 5 or Ark: Survival Evolved? You must first make sure that your computer meets the minimum requirements of the game, otherwise you will not be able to install it.

  • CPU or GPU overclocking: CPU or GPU overclocking refers to fine-tuning the settings so that these components deliver faster speed than the default configuration. Before proceeding, check the specs and stress test the CPU (or GPU) to determine where to start. Overclocking the GPU and CPU can be risky, so it’s a good idea to gather as much information as possible before starting. 

Regardless of what your goal is, keep reading our guide for Windows 10, 8, and 7 to find out how to check all of your PC’s hardware specs, such as installed memory, system summaries, and operating system details.
