Keeping or replacing a computer

A slow computer can make a new one look very tempting. But before spending money, it helps to establish what is actually causing the problem.

Sometimes a repair or modest upgrade is worthwhile. Sometimes replacement is the sensible choice.

Describe the problem first

“Slow” can mean several different things:

It takes ages to start.
Websites load slowly.
One particular program struggles.
Storage warnings keep appearing.
The battery barely lasts.
It freezes, crashes or makes unusual noises.

For example, slow websites on every device may point to the internet connection rather than the computer.

Make a short list of what happens and when. That is more useful than simply saying the machine is old.

Try the straightforward checks

Restart the computer properly, install available updates and check how much storage remains.

Review programs that open automatically at startup and browser tabs or extensions you no longer need.

Avoid downloading an unfamiliar “PC cleaner” because an advert promises an instant cure. It may introduce another problem.

If the computer is crashing or making unusual mechanical noises, make protecting your files the priority before attempting repairs.

Could an upgrade help?

On suitable machines, replacing an older hard drive with an SSD or adding memory can improve performance.

However, some computers cannot be upgraded economically—or at all. Spending on hardware also won’t solve a lack of support for the operating system or essential software.

Ask for a diagnosis and price before committing.

Check security support

A computer can still switch on and run while no longer receiving its normal security updates.

Standard Windows 10 support ended on 14 October 2025. Eligible personal computers may receive limited additional protection through Microsoft’s Extended Security Updates programme. Check the current conditions and your machine’s enrolment rather than assuming it is covered.

Windows 11 eligibility depends on hardware requirements. Macs also have limits on which operating systems and applications they can run.

If you do replace it

Choose for your actual work: email, browsing and documents have different demands from video editing or large design projects.

A refurbished computer may be worth considering if its condition, warranty and remaining software support are suitable.

Before moving, list your:

Important files and photographs.
Software and licence details.
Email accounts and saved passwords.
Printer, scanner and other accessories.
Backup and recovery arrangements.

Keep the old machine until you have checked the transfer. Before donating or recycling it, remove personal data using the appropriate process and sign out of relevant accounts.
