People buy the latest gadgets and technology and load them up with programs they deem necessary for their daily tasks. The equipment may have the best specs, but it slows down and the performance lags after a while. Users then wonder what the cause is for such poor performance.

Computers, mobile phones and other similar gadgets are among the tech hardware people use on a daily basis, helping employees and students finish their tasks efficiently. Moreover, we all use them for browsing sites such as, watching Netflix movies or browsing the news as a few examples during our free time, as well as watching live football, tennis and other sports steamed via said hardware.

Why do computers lag from time to time? Let’s take a look at a few common causes. 

You have to restart the computer

Believe it or not, your computer may lag in performance because you haven’t restarted it in a long while. It’s a pretty common occurrence as you tend to keep your PCs and gadgets on all the time. As a result, the background programs running on your equipment use the resources and cause the performance to dip, affecting the response rate.

You opened a lot of tabs and programs simultaneously

You tend to multi-task, so you open several tabs simultaneously, moving from one tab to another without closing them. This practice leads to slower performance because each one takes a chunk of the RAM. The more programs and tabs open, the lesser processing power available.

There’s a need for additional storage space and memory

This is one of the reasons why you need to check the capacity of your solid-state drive. If the contents reach at least 85 per cent of the capacity, the overall speed is reduced. The virtual space for running the programs becomes barely available.

When it comes to the RAM, if you have several programs eating up a large portion of the memory, you need to close one or two to refresh the capacity. So, unless you get additional RAM, this is always going to happen.

Your computer has a virus infection, or there’s an outdated anti-virus software 

A virus infecting your operating system will affect the speed of your PC, especially if it runs in the background. Other viruses will affect your computer by encrypting files and opening random pop-ups on your screen. Unfortunately, old anti-virus software will not protect your computer from such cyber security threats.

You need to ensure that your system doesn’t have any viruses, so you must download and run a reputable anti-virus program.

Too many software updates

You also allow software updates to upgrade your programs. What you don’t realise is that these updates also increase the storage and memory usage. If you can avoid a software update, and it isn’t that integral, don’t allow it.


There are several reasons why your computer lags in performance, mainly from the human component. You need to look into these habits to improve the speed of your computer.
