Computer Hardware Upgrades

Refresh your old computer with an upgrade.

IBM’s Thomas Watson infamously said in 1943, “I think there is a world market for maybe five computers.”

Computers have come a long way since the days they used to fill up an entire room and now millions of units are sold right around the world. New models come out regularly from big name makers like Apple, Dell, Lenovo and HP, boasting refined features and improvements on the last model. But computers are also much more reliable than they used to be, so people can get a good life span out of their units until its time to get an upgrade.

If you’ve had your computer for several years, chances are it no longer performs quite as efficiently as it used to. Perhaps it’s slow loading speeds, susceptibility to viruses, or an inability to process certain file types. Many users, whether they have a PC or laptop, for work or for leisure, often find that their device does not keep pace with their changing needs or interests. For example, businesspeople may find that their device and operating system does not support the accounting program or teleconferencing system they want to use. Or, at the other end of the scale, users who develop an interest in PC games may feel as though they’re not getting the full gaming experience they want. That’s where we come in!

So how can you tell when your unit needs changing?

When it’s time for an upgrade.

While the pace of progress for computer hardware is impressive, the same can be said for software, a field that brings out new versions of existing products all the time and launches new endeavours regularly.

Though most software is designed to work on a wide range of computers including older models, your old computer will eventually be left behind.

Though you can augment its power with upgrades to things like the processor or graphics card, eventually you’ll be asking ‘why is my computer slow?’

If you feel the need to speed up your computer to keep up with the latest software technology, then it’s a good sign it needs to be upgraded.

Key hardware which determines performance


The short term memory of your computer (aka: RAM) is heavily impacted by the amount of programs you have open simultaneously.

As you open more programs on your computer RAM is consumed and performance is decreased. 

Increasing your memory can be a quick and easy upgrade and allow multiple applications to run with reduced impact to performance.



The “Brain” of your computer. (aka: Processor) is impacted by the complexity and the processing requirements of your applications. 

When users complain about slow starting or loading of programs, an under performing processor is usually the cause of frustration.

CPU upgrades can be a bit tricky and need to be assessed on a case-by-case basis to see if an upgrade is worth the cost.


The long term memory of your computer (aka: Hard Drive) is where your data is stored.

When you download from the internet, import your photos, check your emails or do any action that stores or opens information; your hard drive is used. 

The hard drive has a special impact on performance as an upgrade here can simultaneously speed up loading and increase storage capacity, depending on the hardware upgrade applied.

Getting the right computer for your needs

Before you start looking for a new computer, it’s important to consider your specific needs.

If you use the computer mainly for business, consider what activities you frequently do. If you mainly use the computer for word processing, then a unit with a good amount of memory and some basic features will be just right.

However, if you use the computer for multimedia purposes like video editing then a unit with more storage capacity and a faster processor would be more suitable.

If you use the computer mainly for games, then you’ll need a quick unit with plenty of power for graphics so you get the best experience.
