Where does CefniTech provide computer repairs?

CefniTech provides on-site computer repairs across Anglesey and North Wales. Remote support is available UK-wide.

Do you offer a no fix, no fee guarantee?

Yes. If we cannot fix the fault, you do not pay for the repair.

How quickly can you respond?

Remote support is typically available within the hour. On-site visits are usually same-day or next-day.

Why does my computer get slower when I open multiple IDEs?

Each IDE runs its own background services – language servers, linters and debuggers – which consume RAM and CPU. Closing unused IDEs or using a single, lightweight editor can keep resource usage in check.

Is it safe to use Windows Defender for a development machine?

Windows Defender provides solid real‑time protection and is less intrusive than many third‑party suites. Pair it with regular software updates and safe browsing habits, and it’s sufficient for most developers.

How often should I back up my code projects?

Back up at least once a week to an external drive or cloud storage. For active projects, consider daily incremental backups so you can roll back to the previous day if something goes wrong.

How to Keep Your Development PC Fast, Stable and Secure

Yesterday a freelance game developer walked in, laptop fan screaming, CPU at 100% in Task Manager, and the build wouldn’t even start – we had to act fast. If you spend any time writing code, testing scripts or running compilers, a sluggish or insecure machine can kill productivity and cost you money.

How can I stop background apps from choking my development PC?
We see this a lot: dozens of programmes launch at login and eat RAM. Open Task Manager (Ctrl+Shift+Esc), hit the Startup tab and disable anything you don’t need – Chrome, Spotify, the Adobe updater, etc. A clean startup drops boot time by 30‑40% and leaves more memory for your IDE.
Why should I keep Windows and drivers up to date?
Updates bring performance tweaks and fixes for bugs that can make a compiler crash. Set Windows Update to install automatically overnight, and use the PC manufacturer's support site (or a tool like computer repairs if you’re unsure) to grab the latest graphics and chipset drivers. One hour of updates a month saves hours of debugging later.
What’s the easiest way to free up storage for large codebases?
Large repositories and Docker images fill a drive quickly. Run Disk Cleanup or the built‑in “Storage” settings, delete temp files, and move archives to an external HDD or a cloud service (cloud & Microsoft 365). Keeping at least 15% of the drive free prevents the dreaded “disk is full” errors during builds.
When should I consider a hardware upgrade?
If you hear the fan roar or see “Not Responding” when compiling, it’s time for an SSD and more RAM. A 500 GB SSD cuts load times by up to 70%, and adding a second 8 GB stick of RAM lets you run virtual machines side‑by‑side with your IDE. We can fit a new SSD for around £80‑£120 and install it in under an hour (computer repairs).
How does separating work and personal environments protect my code?
Creating a dedicated user account or, better yet, a lightweight virtual machine for development isolates your tools from everyday browsing and email. If a malicious macro slips through your email, it stays in the personal profile and can’t corrupt your code or steal API keys. The extra step of switching accounts only takes a minute, but it dramatically reduces the risk of ransomware or accidental data loss – a tip we also cover in our cyber security service.
