PC & Laptop Speed Optimisation
Is your PC painfully slow? Before replacing it, let us tune it up. We clear the junk, fix the bottlenecks, and get more performance out of your existing machine.
Measurably Faster
We benchmark before and after so you can see the improvement.
Find the Cause
We diagnose why it's slow rather than just guessing.
Honest Advice
If a hardware upgrade would help, we'll tell you — and quote for it.
What We Optimise
Startup programme cleanup
Background processes and services audit
Disk cleanup and fragmentation (for HDDs)
Temporary files and cache clearance
Browser cleanup (extensions, cached data)
Windows visual effects and power plan tuning
Thermal paste renewal and fan cleaning (if overheating is causing throttling)

Hardware vs Software Slowness
Sometimes slowness is software — junk, startup items, or Windows cruft. Other times it\'s hardware — a failing or full hard drive, insufficient RAM, or a machine that\'s simply overheating and throttling itself.
We identify the real cause. If a hardware upgrade (SSD or RAM) would make a significant difference, we\'ll quote for it alongside the tune-up.

Frequently Asked Questions
It depends on the cause of the slowness. A software-only tune-up typically gives a noticeable improvement. Adding an SSD or RAM on top of that can be transformative — often making a 5–8 year old machine feel current again.
Depends on the age and spec of the machine. We'll give you an honest assessment — if a tune-up or upgrade won't make a meaningful difference, we'll say so.
A software tune-up usually takes 1–2 hours. If we're also fitting hardware upgrades, add a little extra time for fitting and testing.
