Why is my computer so slow

There is nothing more frustrating than a slow computer. Whether it be at work while you’re trying to prepare an urgent report or at home trying to watch your favourite Netflix show a slow computer can be a real bummer.

There can be any number of reasons for a slow computer – from software to hardware and everything in between.

Here are 5 easy fixes to improve your computers speed.

  1. Multiple Programs begin on Start-Up

Your computer may be running slow because as soon as you turn it on programs are starting up. Dropbox, Google Drive, Skype and Anti-Virus programs are just a few programs that start automatically. To see these programs you can check your Task Manager (Right Click on the Start menu for Windows 10) and click on the Start-up tab. Windows 10 makes this easy to check and includes a Start-up impact rating. For those programs you don’t need to start-up every time you turn on your computer (i.e. Skype) you may want to disable them. Word to the wise, consider the importance of your anti-virus program before disabling – there is a reason its start-ups when you turn on your computer.

  1. Virus Check is occurring at the same time

Anti-virus software is important to the security of your data and really shouldn’t be disabled. However, you may find that if your machine is running slow for no reason – check your anti-virus software as it may be running a scan, which may cause your computer to go slower. Regular scans are important, so the best way to ensure you are protected, without being slowed down, is to set a schedule time that isn’t in the peak period of your work day. For example, you may not be busy between 10 and 11 am on Thursdays, so you could schedule the scan for then. Keep in mind that in a business your IT department may manage these schedules, so check with them first. The same goes for home as well, try Saturday afternoon, when your computer may be on, but you aren’t at home.


  1. Disk Clean-Up and Windows Tools

This one is an oldie but a goodie – Disk Clean-up. Effectively your computer can get clogged up with temporary files, Recycle bin documents and system files. These use up valuable space and can slow your computer down. This handy Windows tool is similar across all versions of windows, in Windows 10 it is under Windows Accessories, whereas Windows 7 it is under Accessories – System Tools. This isn’t going to make a massive difference to your computers speed, and is actually more realted to your hard drive, but it still can have an impact if you have a lot of files built up over time.

  1. Have you got enough Memory?

You can have a look at your computer to see if you have sufficient memory to run all of your computers operations. In Windows 10 search for the Resource Monitor in the Taskbar Search Function.

From here you should be able to get to the resource monitor tool. Click on the Memory Tab and make sure you have sufficient spare memory available.

If the physical memory in use is above 80% you should consider an upgrade of your hardware.

Generally, installing memory is not that difficult and is relatively cheap. It’s a great way to speed up your computer, plus you don’t need to purchase a whole new computer.

  1. Remove unused Programs

Chances are if you have an older PC you have accumulated old programs that you don’t use or if you’ve purchased a new PC there are tons of pre-installed programs on there already. The easiest way to remove these programs is to go to the Control Panel and go to the Uninstall Program tool.

This tool shows you when you installed the program and how much space it utilises. By right clicking on the Column headings you can add a new column, called Last Used – this will help you decide if you really need that program from 2012 or not.
