When your gaming PC starts stuttering mid-match, overheating during a long session, or refuses to boot at all, you don't want to ship it off to a call centre and wait a week to hear back. PCC Computers repairs, upgrades and builds gaming PCs and gaming laptops for Unanderra locals from our nearby Dapto and Wollongong CBD stores — both an easy drive from Unanderra along the Princes Highway.

Unlike the generic "computer repair" pages you'll find from national franchises covering Unanderra, gaming PCs are what we actually specialise in. Our technicians work with dedicated GPUs, high-wattage PSUs, liquid and air cooling loops, and overclocked components every day — not just office laptops and printer setups — so we know the difference between a driver conflict, a failing VRM, and a GPU that's about to die.

Common Gaming PC Problems We Fix in Unanderra

Gaming rigs get pushed harder than a typical home PC, and the faults look different too. These are the issues we see most often from Unanderra, Dapto, Kembla Grange and Cordeaux Heights customers:

• Random crashes, freezes or blue screens (BSOD) during gameplay
• Overheating and thermal throttling — FPS drops the longer you play
• GPU artifacting, screen tearing, or a graphics card not being detected
• PC won't turn on, powers off unexpectedly, or won't stay on under load
• Failing or underpowered power supply (PSU) causing shutdowns during heavy loads
• Loud fans, grinding noises, or a case that runs hot even when idle
• Driver conflicts, corrupted Windows installs, or GPU driver crash loops
• Slow boot times, laggy load screens, or a storage drive nearing failure
• RGB, motherboard software or peripheral software not working correctly
• Network stutter or high ping that turns out to be a hardware/driver issue, not your internet

We diagnose properly before quoting — stress-testing components under real gaming load rather than guessing from a phone description, which is the difference between a $60 fix and an unnecessary $400 part swap.

Custom Gaming PC Builds, Upgrades & Component-Level Repairs

Most of our Unanderra gaming PC work falls into one of these categories:

Graphics card (GPU) service

GPU reseating, thermal pad and paste replacement, fan repair/replacement, and diagnosis of artifacting or dead cards. We also handle GPU upgrades if your current card is holding back a CPU that's otherwise fine.

Cooling & thermal work

Repasting CPUs and GPUs, replacing failed AIO pumps, cleaning dust-clogged radiators and fans, and upgrading case airflow for gamers running hot in the Illawarra's humid summer months.

Power supply diagnosis & replacement

An undersized or failing PSU is one of the most common causes of random shutdowns under gaming load. We test PSUs under real load and replace with a correctly-sized unit for your GPU and future upgrades.

RAM, storage & motherboard work

RAM upgrades and compatibility fixes, NVMe/SSD upgrades and cloning, motherboard diagnostics, BIOS updates, and safe, stable overclocking/XMP tuning rather than guesswork settings that crash your system.

Custom builds

Full custom gaming PC builds to your budget and use case — competitive esports rigs, 4K/high-refresh gaming builds, or streaming-ready dual-purpose systems — built and stress-tested in-store before handover.

Streaming, Content Creation & Esports Setup Support

FAQs 

Do you repair gaming PCs in Unanderra?

Yes. PCC Computers repairs, upgrades and builds gaming PCs for customers in Unanderra from our nearby Dapto and Wollongong CBD stores, both a short drive away along the Princes Highway.

How much does gaming PC repair cost in Unanderra?

Cost depends on the fault — a driver or software fix is usually far cheaper than a GPU or PSU replacement. We diagnose your PC under real load first and give you a clear, itemised quote before any work begins, so there are no surprises.

Can you fix a gaming PC that keeps crashing or blue-screening?

Yes. Random crashes and blue screens during gameplay are one of the most common issues we see, and can come from a failing PSU, overheating components, faulty RAM, or driver conflicts. We stress-test to find the actual cause rather than guessing.

Do you repair or upgrade graphics cards (GPUs)?

Yes. We handle GPU reseating, thermal pad and paste replacement, fan repair, artifacting diagnosis, and full GPU upgrades when your current card is bottlenecking the rest of your system.

Can you fix a gaming PC that's overheating or thermal throttling?

Yes. We repaste CPUs and GPUs, clean dust-clogged fans and radiators, replace failed AIO pumps, and improve case airflow — common fixes for FPS drops caused by heat during longer gaming sessions.

Do you build custom gaming PCs?

Yes. We build custom gaming PCs to your budget and use case, from competitive esports rigs to 4K/high-refresh builds, and every build is stress-tested in-store before handover.

Do you offer same-day gaming PC repairs in Unanderra?

In most cases, yes — diagnosis is usually completed same-day, and many common repairs (driver issues, RAM, storage, thermal work) can be turned around quickly. More involved GPU or motherboard work may take longer depending on parts availability.

Can you help with streaming or content-creator PC setups?

Yes. Beyond repairs, we help with capture card installation, encoder and bitrate tuning, dual-PC streaming setups, webcam/microphone configuration, and latency optimisation for competitive online play.

Do you repair gaming laptops as well as desktops?

Yes, we repair gaming laptops too — including overheating, GPU/CPU issues, screen and keyboard repairs, and thermal servicing — alongside our gaming desktop repair work.
