Computer maintenance tips

Regular maintenance is the key to keeping your computer running smoothly and preventing more significant repair expenses in the future. We’ve put together a list of maintenance tips that will increase the life of your PC, reduce the number of maintenance call-outs and will even increase the speed, reliability and overall performance of your computer.

Choosing an IT Company


Whenever your computer's manufacturer has an update available for your computer, we recommend that you download and apply it. It's one of the most effective ways to ensure optimal performance, security and compatibility for your system.

Better yet, why not turn on Automatic Updates. It'll download and install updates automatically, but still, advise for your input if the computer might need to shut down to apply them thoroughly.

Updates are different from upgrades. You should only upgrade your operating system (i.e. Windows 10) if you are sure that all of the applications and programs that you use are compatible first. Upgrading might seem like a great thing to do right away, but if your "go-to" program won't work, then it's a lengthy process to get you back to the previous operating system again.

Computers these days can be exceedingly power-efficient, but this doesn't mean that you should go forever without turning them off. If you're not planning on using your computer over a few days, then it's a great idea to turn it off and give it a refresh. If you're finding that your computer is running a little inconsistent and it's been a while since you've turned it off and on again, do this - it can seriously work wonders. Think of your computer like the human brain. If it doesn't get sleep or take a rest, then it will become dysfunctional – your computer will do the same!

Apps and programs that claim to speed up your computer may be doing the opposite. There are a few things that you can do to clear up your machine instead:

  • Clear cache.
  • Uninstall any unwanted or unnecessary applications/programs.
  • Clear out any unnecessary login/startup items.
  • Install anti-malware programs to get rid of anything malicious (we recommend Bitdefender GravityZone for PC or Malwarebytes for Mac)
  • On a Mac, use Disk Utility to "Repair Disk" on the OS volume.
  • On a PC, remember to do a Disk Defragment.


If you get a suspicious email, don't download its attachment or click on a link inside it, as this could be compromising your computer. Simply delete the email. If you're unsure of the legitimacy of an email, contact the sender through another channel (i.e. maybe over the phone). If you're installing new software, try to keep to Apple's Mac App Store or Microsoft's Store for your installations, as some offerings freely available online carry some hidden annoyances, such as extra toolbars in your internet browser or other unwanted programs. Make sure to read the pages before you click "install", as you don't want to accidentally give permission for something to install that you don't want on your system.


Anti-virus and Malware protection gives you that extra layer of protection.

Apple macOS and Microsoft Windows both have security features and firewalls built-in if you wish to enable them. You can also download and install 3rd party applications and programs that can increase your security. You may have heard of products like Trend Micro and Norton. There are a number of great offerings out there, but try to get one that meets all of your needs at a reasonable price.


A clean you equals a clean computer.

Dirty hands on a keyboard mean you will have a dirty keyboard. Consuming food and liquid around your computer can also pose hazards for spillage and damage. As a rule, make sure your hands are clean before using any electronics wherever possible and only have sealable bottles near your computer. This is an easy way to avoid unnecessary damage and maintenance costs.

If you find that your computer is already quite dirty, such as your computer screen, we recommend cleaning with a microfiber cloth and isopropyl alcohol to clear away germs. Remember to always spray any liquids on the cloth first – never on the computer directly!


Regular maintenance is key.

There are still glitches and issues that can pop up even if you're taking great care of your PC. Depending on your business, Tech Help Direct recommend weekly, fortnightly, monthly or 3-monthly maintenance of your computers to keep them in their best shape.
