What To Do AFTER Building/Buying a PC? [Checklist + Do this first!]

When you thought it was safe to go back in the water, your PC finally does what we all knew was possible. Everything is connected correctly, and now just waiting for that first turn on System Analyzer or installer after installing programs from CD-ROMs…

The sound should be similar with some less emphasis on “system” since there are many ways one can achieve this effect. If you’re using an aftermarket CPU cooler, you’ll first want to check that all the thermal paste / TIM is applied correctly.

Once booted, it will be time to install your graphics card drivers. This can usually be done through GeForce Experience or AMD’s Catalyst Control Center. After that, ensure Windows Update is set to automatically download and install updates at clock speed for individual components.

If you have an Nvidia graphics card, you can also enable G-Sync at this point. G-Sync is a technology that synchronizes the refresh rate of your monitor with your graphics card’s frame rate memory modules. This can help to reduce screen tearing and input lag.

Next, you’ll want to install any drivers for your motherboard. These can be found on the manufacturer’s website. Once that’s done, you should install any driver’s screw holes for your storage devices (SSD, HDD, etc.).

You’ll also want to install any essential programs at this point. This can include an antivirus program, a web browser, and a photo editor.

Now would also be an excellent time to create a backup of your essential files on a flash drive or USB flash drive. This can be done using an external hard drive or a cloud storage service like Google Drive or Dropbox pre-built PC.

Once all that is taken care of, you’re finally ready to use your new PC! Enjoy!

What to do AFTER Building/Buying a PC

Check if it is successfully POSTs.

All the necessary PC parts are in place, and it’s time to hook up your monitor(s), power supply unit (PSU), and input devices power cables to increase in RAM Speed of sensitive components.

You need only a few things to ensure your new PC successfully POSTs. A Power-on self-test or “POST” is the time when an individual’s computer will run through different diagnostics automatically and check if everything works correctly:

  • Make sure all cables connecting from the power supply (or another source) match their respective standards; this includes multiple cords for various devices such as monitors and speakers and keyboards/mouse combo units depending upon model and make.
  • If you have an optical drive (DVD/CD burner), insert a blank disc or data CD/DVD.
  • Turn on the computer and wait for BIOS to complete its POST process; this may take up to several minutes depending upon the individual machine.
  • Look up their corresponding solutions if you see any error messages during the POST. However, if you do not see any error messages and the computer appears to be working correctly congratulations!
  • You have completed one of the essential steps in setting up a new PC.

Install OS and Drivers

After completing the POST process, it is time to install your chosen operating system (OS). For most people, this will either be Microsoft Windows or some form of Linux.

If you’re installing Windows, you’ll need to purchase a copy of the OS and create a bootable USB drive. You can find instructions on how to do this here. Once you have your bootable USB drive, please insert it into your PC and boot from it.

Follow the on-screen instructions to install Windows. Once that’s done, you’ll need to install all of the drivers for your components. These can be found on the manufacturer’s website or included on a disc with your associate.

If you’re installing Linux, you can find OS distributions (versions) here. Once you’ve downloaded the ISO file for your chosen distribution, you’ll need to create a bootable USB drive. Instructions on how to do this can be found here.

Once you have your bootable USB drive, insert it into your PC and boot from it. Follow the on-screen instructions to install Linux. Once that’s done, you may need to install additional drivers for your components. These can be found on the manufacturer’s website or included on a disc that came with your component.

Configure Updates

Once your OS is installed and all of the drivers are up-to-date, it’s time to configure your system’s update settings.

In Windows, you can do this by going to Start > Settings > Update & Security. In Linux, the process will vary depending on your distribution. Consult your distribution’s documentation for more information.

Once you’re in the appropriate settings menu, you should configure your system to install updates automatically. This way, you won’t have to worry about manually keeping your system up-to-date.

Install Important Software

Now that your system is up and running, it’s time to install some important software. This software includes:

  • A good antivirus program: This is essential for keeping your system safe from malware and other online threats. We recommend using either Bitdefender Antivirus Free Edition or Avast Free Antivirus.
  • A good backup program: This is essential for keeping your data safe in case of a hardware failure or other disaster. We recommend using either Cobian Backup or EaseUS Todo Backup Free.
  • A good disk defragmentation program: This helps to keep your system running smoothly by defragmenting your hard drive. We recommend using either Smart Defrag or Auslogics Disk Defrag Free.
  • A good file compression program: This is useful for compressing files so that they take up less space on your hard drive. We recommend using either 7-Zip or WinRAR.
  • A good file recovery program: This is useful for recovering accidentally deleted files. We recommend using Recuva.

What are XMP Profiles?

Once you have installed your OS and all of the drivers, you should check to see if your motherboard supports XMP profiles.

XMP (Extreme Memory Profile) is a feature that allows you to overclock your RAM without having to manually set the timings and voltages. If your motherboard supports XMP, then you can simply enable the XMP profile in the BIOS, and your RAM will be automatically overclocked to its maximum speed.

To check if your motherboard supports XMP, you’ll need to consult your motherboard’s manual. Once you’ve verified that your motherboard does support XMP, you can enable the feature in the BIOS. Instructions on how to do this can be found in your motherboard’s manual.

Once you’ve enabled XMP, your system will be automatically overclocked, and you’ll experience a significant performance boost.

Frequently Asked Questions:

Q: Do I need to install an OS if I’m just using my PC for gaming?

A: No, you don’t need to install an OS if you’re just using your PC for gaming. However, we recommend installing an OS so that you can take advantage of other features such as updates and important software.

Q: I’m not very tech-savvy. Is it difficult to install an OS?

A: No, it’s not difficult to install an OS. The process is relatively simple, and there are plenty of resources available to guide you through the process.

Q: What are some good OS options for gaming?

A: Some good OS options for gaming include Windows 10 and Linux. Both of these operating systems are very stable and offer a great gaming experience.


A building or buying a new PC can be daunting, but it doesn’t have to be. By following the steps in this article, you can be sure that your new PC will be up and running in no time.

Don’t forget to install critical software such as an antivirus program, a backup program, and a disk defragmentation program. And if your motherboard supports XMP, be sure to enable the feature in the BIOS for a significant performance boost.
