Proper diagnostics first, then the right fix. Drop in to the Annacotty workshop or book a callout, and get an honest answer on whether it's worth repairing.
Repairs for laptops and desktop PCs
Whether your laptop won't turn on, your PC keeps crashing or everything has slowed to a crawl, John tracks down the real cause before recommending anything. No guesswork and no upselling.
With over 20 years fixing computers for homes, students and businesses around Limerick, most common faults are quick to pin down, and you'll be kept up to date along the way.
Won't turn on or won't boot
Testing motherboards, power supplies, RAM and drives to find the cause of crashes and machines that won't start.

Board treatment, corrosion removal, ultrasonic cleaning and power rail checks after a spill.

Laptop & PC repair questions
My laptop won't turn on. Is it the battery?
Sometimes, but it can also be the charger, the charging port or a motherboard fault. Try a different socket and check whether the charger light comes on. If it's still dead, bring it in for a diagnosis.
I spilled something on my laptop. What should I do?
Turn it off, unplug the charger and don't try to switch it on or dry it with a hairdryer. Bring it in as soon as you can: the sooner the board is cleaned, the better the chance of a full repair.
Is my old computer worth fixing?
Often it is. Replacing an old hard drive with an SSD can make an older machine feel new for a fraction of the cost of replacing it. John will give you an honest view either way.
Will I lose my files?
Most repairs don't touch your files. If a drive is failing, John will tell you before doing anything and can recover and move your data.
Data recovery
Data recovery in Limerick
Work files, family photos and important documents recovered safely and confidentially from damaged or unbootable drives.
Lost files? Stop and get in touch first
When a laptop won't start, an external hard drive stops showing up or a PC dies, your files are often still there. The most important thing is to stop using the drive: carrying on can overwrite exactly what you're trying to get back.
John recovers data from laptops, desktops and external hard drives, handles everything confidentially, and keeps you updated as he works through it.
Failed & damaged drives
Recovering files from hard drives and SSDs that are failing, corrupted or no longer detected.
Dead laptops & PCs
Getting your files off a computer that won't power on or boot, and moving them to a new machine.
Liquid-damaged machines
Recovering data from laptops after spills, alongside the board repair where possible.
Confidential handling
Business records and personal files treated with care and discretion from start to finish.
Backups so it doesn't happen again
Automated cloud backup set up afterwards, so your files are protected in future.
Lost files? Stop using the drive and get in touch now.
The sooner John looks at it, the better the chance of getting everything back.
Data recovery questions
Can my files be recovered?
In many cases, yes, especially if the drive hasn't been used much since the problem started. John will check the drive and tell you what can be recovered.
What should I do while I wait?
Stop using the drive, don't keep restarting the computer, and don't run repeated recovery tools on it. Each attempt can make things worse.
Is my data kept private?
Yes. Recovery is handled confidentially, whether it's business records or family photos.
Can you recover from an external hard drive?
Yes, external hard drives are a common job, along with laptop and desktop drives.

Gaming rigs need serious cooling, clean power delivery and careful thermal management. When something's off, it usually shows up as high temperatures, FPS drops, shutdowns under load or artifacts on screen.
Ask about your rig- Hardware diagnostics & thermal re-pasting
- Full strip-down & deep clean
- GPU, CPU, RAM & PSU upgrades
- Component sourcing advice
Gaming PC questions
My gaming PC is overheating. What can you do?
Usually a deep clean and fresh thermal paste on the CPU and GPU. John will also check fans and case airflow.
My PC shuts off when I play games. Why?
Common causes are an underpowered or failing power supply, or the CPU or GPU overheating. Both can be tested.
Can you fit parts I've bought myself?
Get in touch with the parts list and John will check they're compatible before fitting.
Which upgrade will make the biggest difference?
It depends on your current CPU, GPU, RAM and power supply. Send the details and John will advise.
