Signs You Should Clean Up Your Computer

A slow computer can be one of the most frustrating things about technology. But, how do you know when your computer is running slow for a reason you can fix and when it is slow just because of outside influences? 

Here are some things to look for:

  • You’re working in a program, and it suddenly stops working.
  • Browsers or apps run incredibly slow.
  • You’re running out of disk space.
  • It takes forever for your computer to reboot.
  • Your screen suddenly freezes

Benefits of Cleaning Your Computer

When you’re having issues with things like computer speed, then the decision to clean up the computer can be a beneficial one. Here are just a few of the reasons why learning how to clean out a computer can make it run better than ever.

  • It will run faster.
  • You won’t have to worry about programs crashing.
  • By cleaning the inside of a computer, it will be more reliable.
  • You’ll extend the life of your computer.

How to Clean Up Your Computer on the Inside

We’re going to go over how to clean a PC. The following information will provide you with all of the steps you need in order to get your computer just as clean inside as it is on the outside. 

Disk Cleanup

Windows disk cleanup is the utility to use whenever you want to defragment your hard drive. You’ll definitely want to do this as part of cleaning up your computer. Without defragmenting, you could keep running into problems. 

Windows 7 

You’ll open it by doing the following:

  • Go to the “Start: button.
  • Select “All Programs.”
  • Choose “Accessories.”
  • Now go to “System Tools.”

Windows 8 and Above

The easiest way is to do the following:

  • Hit the “WIN” key.
  • Type in “Disk Cleanup.”
  • Now, choose “Free up disk space by deleting unnecessary files.”

Please note: The following directions apply to any PC system you have. 

  • Select the proper drive.  Once “Disk Cleanup” begins, you’ll select the drive you want to defragment. 
  • Choose what space to free up. The “Disk Cleanup” tool will show you what is taking up the most space on your computer. You can select what you’d like to have removed. Be sure you’re in administrator mode so that you have access to all files on the computer. If you’re in a lesser mode, you won’t have permission to see everything that could be impacting your computer’s performance.

Disk Defragmenting

Go to the start menu and type in “defrag” in the search box. This will bring up your defragmenter tool. You’ll likely see that your computer is already defragmenting files on an automated basis. See what it’s set to, and choose the one that works best for you, such as weekly or monthly. 

You can now choose the drives that you want to have defragmented automatically. If there are any you choose to optimize manually instead, you’re able to make that selection here. It’s much easier to let your computer do that work for you, though. 

Programs and Features

Go to the “Control Panel” to open up “Programs and Features.” This will bring up a list of all of your programs. Go through them and remove any that you’re not using. Be sure to view the programs according to the largest file size. This way, you can remove the programs that are taking up the most space first. 

How to Wipe a Laptop Clean on the Outside

Here, we’ll go over the ways you can clean your computer in terms of ridding it of dust, fingerprints, etc. First, here are some of the things you’ll need:

  • Microfiber cleaning cloths
  • Q-tips
  • Rubbing alcohol
  • Compressed air can

Now, here are the steps you’ll need to take to clean the exterior of your computer.

  • For safety reasons, turn the computer off and unplug it.
  • Lightly dampen a microfiber cleaning cloth and wipe down the surface. Be sure the cloth is just damp, not wet. You never want water getting inside a computer.
  • If you have a mouse to clean, use just a touch of rubbing alcohol and a cloth. 
  • For the keyboard, you can use a compressed air can. 
  • Last, dab q-tips in rubbing alcohol, and clean up the keys to give them a shine. 

How to Clean Your Computer Screen

When you’re cleaning a computer screen, be sure it’s completely turned off and unplugged. Next, follow these steps:

  • Use a dry cloth and wipe the screen in a straight motion from side to side. 
  • Now, dampen the cloth and continue wiping it down. 
  • Never use a cleaning solution. However, if the water isn’t cutting it, you can make your own safe solution. It’s 50% vinegar and 50% water.

That should do the trick. You can even try a wax on and wax off motion if the side to side technique didn’t quite do the trick. It shouldn’t take much with your computer screen, and you don’t want to overdo it. 

When Should You Take It to a Professional?

External Cleaning

Don’t. You can easily clean your computer, freeing it of dust and fingerprints. You just need to set aside the time to do it and be sure you have the items you need in order to clean it. There’s no need for a professional here unless you don’t have the time to do it yourself, and paying someone would be more convenient for you. 

Internal Cleaning

It depends on how technologically capable you are. Only take it to a professional when you’ve reached a point where you’re not able to determine what the problem is. Maybe you’re seeing strange error signs, or you’ve gone through everything in your toolbox, and it is still not working. Then, it’s probably best to seek advice.


Computers require a lot of maintenance, and that maintenance can get expensive. Using the tips found in this article can help you save a lot of time and money. You’d be surprised what you’re capable of doing on your own if you’re just willing to follow instructions.
