My computer is slowing down and crashing a lot. What should I do? Windows edition.

Updated: Nov 18, 2019

It is frustrating when it happens and we know how you feel. Distraught and frustrated at these machines you paid so much money for. It should work well but it does not. Applications take a long time to load, starting it up also takes a really long time. Worst of all, it keeps crashing on you. You have no clue as to what is wrong. Let us help you figure it out together.


Let's start with the easiest and most probable cost. Sometimes your RAM just comes a little loose. Some static build-up and gradual minuscule vibration from your fans are enough to dislodge it from its the place. It could be the reason why your computer is crashing, it has no ram or random access memory to allocate the processing to. Your processor uses the memory to perform select calculations for programs that are running, especially those running in the background.

If you are confident, you can simply clean your ram. Here is another video tutorial one installing and removing ram. It could just be a simple dust issue that has resulted in what has happened to your system. And for your sake, we really hope that is really the case. Following this, you can start your computer back up again. This is not the end of the process just yet, what we want you to do is to start and run "DXDIAG" which is a built-in diagnostic application to read all the hardware that is connected to your computer. Click here to learn how to do that.

Alternatively, all you need to do is to click on the magnifying glass button and type 'dxdiag' and the application will launch. For older versions of windows, click on start>run and then type 'dxdiag'. Once you have done that you should see the application load and eventually the same window is shown here. From the name of your computer, version of an operating system all the way down to the version of DirectX you are using. Ignore all of those and look for "Memory". Remember, one thousand megabytes or MB is equal to one gigabyte or GB. If you are aware of how much ram you have compared that number with what you see. If the number is less than half the amount of ram you have, your ram is faulty. This will be an easy fix, just buy new ram. Time for an upgrade.


Another common reason is simply dust. Parts on your main board or mother board requires constant cooling during operations. This is because electrical signals running along the copper threads generate heat and if unchecked, the heat can possibly cause overheating issues. And your CPU chip needs the most cooling. The moment your CPU overheats, everything freezes and your computer crashes. Commonly this is because dust has clogged up your CPU fan.

Just like a house fan, the dustier it gets the less effective it gets. So time to bring out the vacuum cleaner to suck up all that dust. Shut down your computer, open up the casing and start cleaning away. One of the better ways is to buy some compressed air cans available at your closest computer hardware store and blast those dust out of those hard to reach places. They say if pulling does not work, try pushing. That is what we always say actually. But yeah, when it comes to dust, sometimes a vacuum cleaner is not strong enough. Over time dust can get pretty clingy and hard to suck out of the tiny crevices inside your computer fan and cooling heat sink.

Maybe before doing that you might want to watch this video. Might we also suggest something, if cleaning the CPU fan works and your computer stops crashing? And if you are using a desktop computer, you may want to consider upgrading your fan to a beast. You do not have to spend more than fifty dollars and make your computer last a really long time.

Operating system

Please do note, this blog is about identifying the problems we are confident you can solve yourself. Any advanced underlying problems are best resolved by a professional. Moving on, say your ram is working and your computer is clean and your Windows operating system loads. It still crashes after a while. You are not running out of options, it could be possible that your operating system is corrupted. It is entirely possible that malware has entered your system and corrupted many files needed to run your computer properly.

Thing is, this is the point beyond repair if malware has caused all of this. What we mean to say is you will not be able to remove the virus since it does not allow Windows to run long enough to do anything about it. So the next step we will have to do is to repair windows or reinstall it completely.

Repairing is the better option here. You have files that might be crucial and repairing may allow you to salvage these important files. Before doing a full re-installation. You will have to work out your license. And you will need to use another computer to download these installer files. Here are some links that may prove useful:

  • Speccy - Install and run application this to find out your windows license.

  • Windows 10 - Download the ISO file for Windows 10 here.

  • Windows 8 - Download the ISO file for Windows 8 here.

  • Windows 7 - Download the ISO file for Windows 7 here.

  • Windows USB tool - This will make a bootable USB with your windows ISO file.

  • Driver Booster - This is for after the re-installation. The driver booster will source and install all the drivers for your computer components. Easy and simple to use.

Do be patient when downloading the windows installer files and try to get a freshly formatted USB drive stick to install the windows installer into. So now that you have run Speccy and found out your license key and have windows installer in the USB. Where do we go from here? Plug in your USB and restart your computer and access the boot menu. Read here to learn how to access the boot menu.

Once you are in the boot menu, boot from the USB and you should see the Windows logo appear. And if you do, congratulations you are now in the right place. Now if you do not have any important file to save, we recommend you proceed straight to a fresh install instead of a repair. If we are being honest, we prefer a direct re-installation anyway, it is way less complicated and straightforward. But yes go and carry on with the repair and follow the steps. Also, if the entire process happens, whether it be repaired or reinstall without crashing. Smile, you have successfully found the problem! It is no longer crashing.

Still crashing?

First and foremost. We are so sorry to hear that. We feel you and we have been there. It is not an easy feeling and it is your hard-earned money that went down the drain.

You will have to bring it down to a professional at this point. You should be proud of yourself. You have done everything you can to solve the issue and you can hold your head up high. We wish you all the luck and hope they can repair the problem without costing you an arm and a leg. But be prepared for the worst-case scenario. In the event when it is your laptop's main board that is no longer operational, it might be time to buy a new laptop. If it is a desktop the repair might be easier and cheaper. Since all you most likely need is just a new main board and processor.
