Walk into any office in Cape Town, and you might still find a desktop quietly humming away from 2018. For many businesses, computers are seen as long-term assets, but holding onto outdated hardware may cost more than you think.
So, when is the right time to replace your business PCs?
The 3-4 year rule
Most experts agree: the ideal window to replace business PCs is every three to four years. After this point, machines begin to slow down, repairs increase, and security risks multiply.
Intel research shows that helpdesk calls for older PCs rise by over 50% in year four, and employees lose up to 42 hours a year due to performance issues. That’s a full workweek lost per employee, every year!
Desktops can stretch to five years, while laptops, thanks to battery wear and portability damage, generally need replacing sooner. Power users like designers or developers may require even more frequent upgrades.
The cost of hanging on
“The costs of old machines aren’t always obvious,” says IT consultant Mark du Toit. “But downtime, slower performance, and frequent support calls add up.”
According to Microsoft and Intel, PCs older than four years cost businesses R50 000 per year, per machine in lost productivity, downtime, and maintenance – double what it costs to maintain newer devices.
Security is another concern. Windows 10 reaches end-of-life support in October 2025. Older PCs that can’t upgrade to Windows 11 will become more vulnerable, increasing the risk of breaches and data loss.
When to upgrade
Common red flags include sluggish startups, overheating, frequent crashes, and apps failing to run properly. “If one machine is being logged for issues every week, it’s already costing more than it’s worth,” adds Du Toit.
Budgeting for upgrades
A smart solution is the phased refresh strategy – replacing 20-25% of your hardware every year. This avoids large capital outlays while ensuring your tech remains current.
Keep an updated asset register noting purchase dates, warranties, and performance issues. This helps you plan replacements in advance instead of reacting to sudden failures.
Think beyond disposal
Strategic replacements also allow for older machines to be refurbished or donated before they become e-waste. Several Cape Town NGOs and schools accept working PCs for training and education purposes.
An investment, not a grudge purchase
Replacing PCs can feel like an expense to delay, but doing so often costs more in the long run. In a digital-first business world, reliable hardware isn’t a nice-to-have – it’s essential.
If your business still runs on machines older than your smartphone, it’s time to ask: Are your PCs helping you grow, or just helping you get by?
