PC Repairs & Upgrades
In short
- We repair desktop and gaming PCs at component level — graphics cards, motherboards, hard drives and SSDs, power supplies, and RAM or boot faults.
- Every job starts with a £65 flat-rate diagnostic. You get the fault and a quote before anything goes ahead, and nothing proceeds without your approval.

- We upgrade any desktop PC, regardless of where it was bought or built.
- Most repairs are finished within 3 to 5 working days once you have approved the quote. More involved faults take longer, and we tell you that upfront rather than after.
- Our labour is guaranteed for 30 days, and any new parts we fit carry the manufacturer's own warranty.
- Open 7 days a week, 07:00 to 22:00.

Diagnostic Fee & Pricing
Every repair or upgrade starts with a full diagnostic to identify exactly what is wrong or what is needed.
Flat-rate diagnostic fee
- Hardware fault confirmed? The £65 covers the diagnostic. We then quote separately for parts and labour — you decide whether to proceed.
- User error or software issue? The £65 fee still applies as our time diagnosing is the same regardless of the cause.
- No hidden costs. You approve the full written quote before any work begins.
Repair Services
We repair desktop PCs and custom gaming computers. Common faults we fix regularly:
- PC won't power on — PSU failure, motherboard fault, or loose internal connections
- No display or blank screen — GPU failure, monitor cable issues, corrupted BIOS
- Blue screen of death (BSOD) — driver conflicts, failing RAM, or storage faults
- Overheating and thermal throttling — dried thermal paste, blocked fans, failing cooler
- Slow or sluggish performance — failing HDD or SSD, RAM issues, software bloat
- Noisy fans or rattling — worn bearings, heavy dust buildup, incorrect fan curves
- USB or peripheral ports not working — motherboard header faults, driver issues
- Random shutdowns or freezes — PSU instability, overheating, failing components
Not on the list? Contact us anyway. If we can fix it, we will. If we cannot, we will tell you honestly before charging anything beyond the diagnostic fee.
Component-Level Repairs
Most faults come down to one part. These are the repairs we are asked for most often, and what each one usually involves.
Graphics card repair
Artefacts on screen, crashing under load, fans spinning at full speed, or no display at all. We test the card in a known-good system to separate a genuine GPU fault from a power supply, riser or motherboard problem — a surprising number of "dead" graphics cards turn out to be a failing PSU. Where the card itself has failed we will tell you plainly whether a replacement is the sensible option, and we can fit a new one from the same range we use in our builds.
Motherboard repair
No power, no POST, dead USB headers, or a machine that boots only sometimes. We check the power delivery, RAM slots, CMOS battery and standoffs before condemning a board. If the board has failed we quote for a like-for-like replacement that keeps your existing CPU and memory wherever possible, so you are not forced into a full rebuild.
Hard drive and SSD repair
Clicking drives, drives that vanish from BIOS, very slow boots, or repeated corruption. We check SMART data and surface health first. Where a drive is failing but still readable we can clone your data to a new NVMe SSD as part of the upgrade — usually the single biggest speed improvement an older PC can get. We are not a clean-room data-recovery lab, so if a drive has failed mechanically we will say so rather than take your money.
Power supply faults
Random shutdowns under load, no power at all, burning smell, or a PC that restarts when a game starts. A failing PSU imitates almost every other fault, which is why we test it early. We fit 80+ Gold fully modular units, matched to your graphics card.
RAM and boot faults
Blue screens, failure to POST, or a machine that only boots with one stick fitted. We test each module individually and in each slot, so the fix is the actual faulty part rather than a guess.
Upgrade Services
Already have a PC but want better performance? We supply and install brand-new components:
We only use brand-new components from reputable manufacturers — the same parts used in our custom builds. All upgrades are stress-tested before handback.
Computer Repair in Littlehampton & West Sussex
We are a local computer repair workshop in Littlehampton. We fix desktop computers and custom gaming PCs at component level, so you are told what actually failed rather than sold a part on a guess. Diagnosis is a flat £65 and you approve a written quote before any work starts.
Most customers drop their machine in and collect it once the quote is approved. We regularly take drop-offs from Worthing, Bognor Regis, Arundel, Rustington, Chichester, Shoreham-by-Sea, Brighton, and from Angmering, Lancing, Goring-by-Sea, Ferring, Storrington and Pulborough. If you are further away, a PC can be couriered in from anywhere in the UK — contact us first so we can expect it.
Please note: we repair desktop computers only. We do not repair laptops or all-in-one machines.

Frequently Asked Questions
How much does graphics card repair cost?
Diagnosis is a flat £65. What follows depends on the fault: if the card is fine and the real problem is the power supply or a cable, the repair is usually inexpensive. If the GPU itself has failed, we will quote for a replacement and tell you honestly whether it is worth spending the money on that machine. You always see a written quote before we do anything.
Do you repair graphics cards, motherboards and hard drives?
Yes — those three are the most common jobs we see. We diagnose at component level rather than replacing parts on a hunch, so you are not paying for a new graphics card when the fault was a failing power supply.
Can you recover data from a failing hard drive?
If the drive is still readable, yes — we can clone it to a new SSD and hand your data back working. If it has failed mechanically, that needs a specialist clean-room recovery service and we will tell you straight away rather than charging you to find out.
Is there a PC repair service near me?
If you are anywhere in West Sussex, yes. Our workshop is in Littlehampton and we regularly take drop-offs from Worthing, Bognor Regis, Arundel, Rustington, Chichester, Shoreham and Brighton. If you are further away we can arrange a tracked courier collection from anywhere in the UK.
How long does a repair take?
Most repairs are completed within 3–5 working days once you have approved the quote. Complex faults such as liquid damage or motherboard-level issues may take longer — we always give a realistic timeframe upfront.
Do you repair laptops?
We specialise in desktop PCs and gaming computers. We do not currently repair laptops or all-in-one machines.
What if my PC cannot be repaired?
We will tell you honestly after the diagnostic. The £65 fee still applies as our time assessing the machine is the same regardless of the outcome. We can then advise on a replacement custom build if needed.
Do I need to bring it to you in person?
You can drop off at our Littlehampton workshop or we can arrange a tracked courier collection. Contact us to discuss the most convenient option.
Is there a warranty on repair work?
Yes. Any new components fitted carry the manufacturer warranty. Our labour is guaranteed for 30 days — if the same fault reoccurs within that period we will rectify it at no additional charge.
What areas do you cover?
We are based in Littlehampton, West Sussex, and regularly take drop-offs from Worthing, Bognor Regis, Arundel, Rustington, Chichester, Shoreham, Brighton, Angmering, Lancing, Goring-by-Sea, Ferring, Storrington and Pulborough. We also accept couriered-in PCs from anywhere in the UK — contact us first to confirm.
Can you upgrade a PC you did not build?
Yes. We upgrade all desktop PCs regardless of where they were bought or built. The same £65 diagnostic applies to assess compatibility before we quote for parts and labour.

Yes. Our workshop is in Littlehampton, West Sussex, and computer repair is what we do there every day. We handle desktop computers and custom gaming PCs, diagnose the fault for a flat £65, and give you a written quote before any work begins. You can drop your machine in and collect it once repaired.
How much does computer repair cost in West Sussex?
Diagnosis is a flat £65 whatever the fault turns out to be. The repair cost itself depends on what failed, and you see a written quote before we start. If a machine is not worth repairing we will say so honestly, and you pay only the diagnostic rather than money spent on a lost cause.
