Voltage irregularities and PSU replacements

We test your hardware using tools like MemTest86, CrystalDiskInfo, HWMonitor, and in-house bench testing to confirm the issue before any repair is done

💾 Software Troubleshooting

System instability, strange pop-ups, or sluggish performance usually stem from software conflicts, OS errors, or corrupted system files. We fix

Windows 11/10/8 boot errors 

macOS kernel panics and startup loops 

Driver conflicts and missing DLLs 

Corrupted system files and registry problems 

Blue Screen of Death (BSOD) diagnosis and fix

Our team can optimise your router configuration, upgrade drivers, and re-establish stable, high-speed connections across your home or business network.

🛡️ Virus & Malware Removal

Suspicious browser pop-ups, ransomware alerts, and unexplained system slowdowns are red flags. We remove threats and restore system integrity by

Scanning and eliminating viruses, trojans, spyware, rootkits, and keyloggers 

Installing and configuring antivirus programs like Malwarebytes, Bitdefender, or Avast 

Removing browser hijackers and unwanted pop-ups 

Restoring corrupted or blocked system files 

We ensure your system is clean, protected, and optimised to avoid reinfection.

fantastic service. Fixed our PC issues easily and gave great explanations on how to prevent issues in the future as well as giving us lots of tips to make being online a more user friendly experience. His hourly rate is the cheapest weve found. Would definitely recommend his service!

Received a leaflet in the mail a couple of weeks ago (normally i just throw them away), this one caught my eye so i kept it. Had to call Robert today and WOW he is great. He explained the options i had and costs and was explaining everything along the way. His price is the cheapest i have come across by far and he really does know what he is doing (seen other techs come in do what they say is the job and a few days later we have the same problem). I would definitely recommend him for all your computer needs, plus he does so much more 🙂 THANKS AGAIN FOR THE EXCELLENT SERVICE

Robert has been so helpful and nothing was too big or too small to fix. As an "oldie" he recommended a new computer to fit my needs which saved me the worry of trying to decide. Have used him for many years and he will definitely stay on my go to list for computer help. Fantastic!

My lap top had the dreaded blue screen with the frowny face… Robert pulled it apart hoping to be able to fix it by illuminating possible causes. In the end it wasn’t worth fixing… it was 5 years old anyways. Robert spend time, without charge transferring all my data to my new lap top. Thanks Robert. Defs recommend. His honest and takes time to find resolutions. 5 stars!!

Because we don’t guess—we diagnose, explain, and solve.

When your computer’s acting up and you’re not even sure what’s causing the issue, Zoo Computer Repairs is your ideal go-to. We specialise in making the complicated simple, even if all you know is that “something’s not right.” Here’s what makes us stand out from the rest

We Think Like Engineers, Not Salespeople

We’re not here to upsell or convince you to buy a new computer—we’re here to fix the one you’ve got. Our approach is logic-driven, using real data and diagnostics rather than assumptions or unnecessary part replacements

Deep-Level Troubleshooting, Not Surface-Level Fixes

Where others might stop at basic virus scans or a system reset, we go further. We test components individually, analyse system logs, and even check the motherboard and BIOS health if necessary. Whether it’s a failing hard drive, corrupt system file, or something more obscure, we find it

Clear Explanations – No Geek Speak

We take the time to explain the problem in everyday language. You’ll understand what’s wrong, what needs fixing, and why—no confusing tech jargon or vague answers.

No-Fix, No-Fee Option Available

We offer a “no-fix, no-fee” policy on eligible diagnostics, so you won’t pay unless we can help. It’s our way of guaranteeing value for money.

Honest Diagnostics, No Unnecessary Repairs

We don’t charge for unnecessary services. If your system is fine, we’ll tell you. If it needs a simple software tune-up, we won’t pretend you need new hardware
