Overview

Get the frames back — gaming PC repair done properly

A gaming rig fails differently to an office PC: the GPU artefacts under load, thermals throttle mid-match, a marginal PSU trips on a boss fight, or an overclock that ran fine for a year starts blue-screening. We diagnose the actual failure — not just reinstall Windows and hope — on prebuilt and custom desktops, water-cooled loops, and gaming laptops. Work is carried out at our Putney workshop in South West London, with collection across London and honest advice on whether a part is worth repairing, replacing or upgrading.

What you get

What every gaming pc repair job includes

90-day warranty

The work we carry out is covered by a 90-day warranty. If the same fault comes back inside that window, we put it right.

Free collection and return

We collect and return across South West London at no charge, so you do not have to make the trip to get your machine looked at.

Common parts held in stock

Screens, batteries, keyboards, RAM and SSDs for the models we see most are on the shelf at our Putney workshop, so the usual jobs are not waiting on a supplier.

Same-day turnaround is available on many jobs — ask when you book and we will confirm availability and any additional cost before we start.

Features

What's Included in Our Gaming PC Repair

GPU Diagnosis & Repair

Artefacts, black screens, driver timeouts and crashes under load. We isolate whether it's the card, the slot, the PSU or thermals, and handle reseating, repaste, fan and — where economic — board-level GPU work.

Thermal & Cooling

Thermal throttling, loud fans, and dust-choked coolers. We repaste the CPU/GPU with quality compound, service or replace air and AIO coolers, and correct case airflow so clocks hold under load.

Stability & Crash Fixing

Blue screens, freezes and crashes-to-desktop under load. We stress-test to reproduce the fault, then trace it to RAM/XMP, an unstable overclock, storage, drivers or a failing component — not guesswork.

Power & No-Boot

Won't power on, shuts down mid-game, or restarts under load. We test the PSU properly, check power delivery to the board and GPU, and replace failing units with correctly-rated, quality supplies.

Custom Loops & Fans

Custom water-cooled builds serviced and repaired — pump faults, leaks, air locks, coolant top-ups, and fan/RGB replacement — with care taken around your components and cable management.

Stress-Tested Return

Every repair is verified under real gaming load — GPU and CPU stress tests, temperatures and clocks checked — so you collect a rig that holds up in-game, not one that just boots to the desktop.

Process

How a Gaming PC Repair Works

Simple steps to get your problem solved quickly and professionally.

1

Diagnose

Bring the rig in or book a collection. We stress-test to reproduce the fault under load and isolate the actual failure — GPU, thermals, power, memory or storage.

2

Quote

You get a clear quote with parts, labour and turnaround before any work starts. If an upgrade makes more sense than a repair, we'll say so.

3

Repair

Approved work proceeds with correctly-rated, quality parts. We keep your build tidy — cable management and airflow restored, not left worse than we found it.

4

Verify

We re-run GPU and CPU stress tests and check temperatures and clocks under sustained load, then hand back a stable, game-ready machine.

How gaming PC faults actually present

Gaming loads push every component to its limit, so faults show up under stress that a normal desktop never reveals:

It only crashes in games

A rig that's stable on the desktop but crashes under load is almost always a thermal, power or overclock/XMP issue — the extra draw exposes a margin that isn't there day-to-day. We stress-test to find it.

Artefacts and visual glitches

Coloured lines, flickering textures or scrambled images point to the GPU, its power delivery or overheating — not usually the game or drivers. We isolate the card from the rest of the system.

Frame drops and stutter

Sudden frame drops mid-session often trace to thermal throttling or a storage bottleneck rather than the GPU being 'too slow'. Fixing airflow or storage frequently restores performance.

Shuts down mid-match

A hard power-off under load usually means an overheating component hitting its limit or a PSU that can no longer deliver peak draw. Both are fixable once correctly diagnosed.

The common thread: reproduce the fault under real load first, then fix the cause. Guess-and-swap wastes money on gaming rigs.

Repair, or upgrade? Honest advice

Gaming hardware moves fast, so sometimes the smart money is on an upgrade rather than a repair. We'll be straight with you:

  • If the fault is cheap to fix and the components are still capable, repair almost always wins
  • If a failing part is already a bottleneck, upgrading it can cost little more than repairing it — and you gain performance
  • For older rigs, we'll tell you when the sensible spend is a targeted upgrade rather than repairing ageing parts
  • We quote both options where it's a genuine judgement call, so the decision is yours

Whether it's a fix or a fresh build, our custom PC build and upgrade work are handled by the same in-house team.

FAQ

Frequently Asked Questions

How much does gaming PC repair cost?
Diagnostics and software or stability fixes start from £45. Hardware repairs — GPU work, thermal repaste, PSU replacement, cooling repair — are quoted individually after diagnosis, based on the fault and any parts needed. You get a clear price before any work begins, and if an upgrade makes more sense than a repair we’ll tell you.
Do you repair gaming laptops as well as gaming desktops?
Yes. We repair gaming laptops as well as desktop and custom-built rigs — overheating and thermal throttling, GPU faults, fan replacement, charging and power problems, and crashes under load. Gaming laptops run hot and benefit from a repaste and clean-out; we handle that alongside any hardware fault.
My gaming PC keeps crashing or blue-screening under load — can you fix it?
Usually, yes. Crashes that only happen under gaming load are one of the most common jobs we see. We stress-test to reproduce the fault, then trace it to the real cause — an unstable overclock or XMP profile, failing RAM, a marginal PSU, thermal throttling, storage errors or driver issues — rather than just reinstalling Windows and hoping.
Can you fix GPU artefacts or a graphics card with no display?
Yes. We diagnose whether the problem is the graphics card itself, the PCIe slot, insufficient or failing power, or thermals. Fixes range from reseating and a repaste through to fan replacement and, where it’s economic, board-level GPU repair. If the card isn’t worth repairing we’ll advise on a sensible replacement.
Do you work on custom water-cooled builds?
Yes — we service and repair custom loops as well as AIO coolers: pump faults, leaks, air locks, coolant top-ups, and fan or RGB replacement. We take care around your components and cabling, and stress-test temperatures after any cooling work.
Do you build or upgrade gaming PCs too?
Yes. Alongside repairs we offer custom PC builds and upgrades — GPU, CPU, RAM, storage and cooling — spec’d to your games and budget. If your machine is more upgrade than repair, we’ll quote both so you can decide.
Where are you based and do you cover my area?
Our workshop is at 66 Lower Richmond Road, Putney, SW15 1LL. You can drop your rig in, or we can collect and return it across London. We cover Wandsworth, Battersea, Clapham, Fulham, Wimbledon, Kingston and the rest of South West London.
My rig won't POST after a motherboard BIOS flash — can you recover it?
Frequently, yes. Flashing a motherboard BIOS to chase a CPU-compatibility or stability fix, then having it fail partway, can leave a gaming PC powered but with no display and no POST. Our BIOS chip reprogramming and firmware recovery service reads and verifies the SPI flash chip, reprograms it with the correct official firmware, or fits a programmed replacement chip. We assess the board first, as a no-POST fault can also be GPU, PSU or memory-related.
