If your gaming PC is crashing mid-match, running hot, freezing on boot, or just isn't performing the way it used to, PCC Computers is the local team Mount Warrigal gamers trust to sort it out properly. We're based just down the road at Stockland Shellharbour, open seven days, so you don't have to box up your rig and wait days for a courier or a call-out tech to squeeze you into a schedule.

Whether you've built your own rig, bought a pre-built tower, or you're gaming on a laptop that's started throttling and shutting down under load, our technicians diagnose the fault properly before touching anything — no guesswork, no unnecessary part swaps, no inflated "just replace the whole motherboard" quotes.

Common Gaming PC Problems We Fix

• Random crashes, blue screens (BSOD) or freezing during gameplay
• Overheating, loud fan noise, or thermal shutdown under load
• GPU faults — artifacting, black screens, driver crashes, dead outputs
• PC won't POST, won't boot, or gets stuck on the motherboard logo
• Poor frame rates or stuttering that doesn't match your hardware specs
• PSU failures, sudden shutdowns, or random restarts
• RAM errors, blue screens tied to memory faults, or failed stress tests
• Liquid cooling leaks, pump failures, or AIO cooler faults
• Storage issues — slow load times, drive failures, or corrupted game installs
• Coil whine, unusual noises, or components that feel physically off

Gaming Laptop Repairs

Gaming laptops take more punishment than a desktop rig ever will — cramped internals, constant heat cycling, and far less airflow. We repair gaming laptop screens, keyboards, hinges and charging ports, replace failing batteries, clean out dust-choked heatsinks that are causing thermal throttling, and diagnose GPU or motherboard faults specific to laptop chassis. If your gaming laptop is running hot, shutting down mid-session, or the fans are constantly screaming, bring it in and we'll find out exactly why.

Upgrades & Performance Tuning

Not every gaming PC problem is a fault — sometimes your rig just needs an upgrade to keep up with newer titles. We handle GPU upgrades and installs, RAM upgrades, SSD/NVMe storage upgrades and cloning your existing setup across, CPU and cooler upgrades, PSU upgrades to support higher-draw components, and full case/airflow rebuilds if your thermals are holding you back. We'll talk you through what will actually make a difference for the games you play, rather than upselling parts you don't need.

Custom Gaming PC Builds

Want a gaming PC built specifically around your budget and the games you play, rather than a generic pre-built with parts you didn't choose? We build custom gaming PCs from the ground up — component selection, cable management, thermal tuning and stress-testing included — so Mount Warrigal gamers get a rig that's actually built for them, backed by a team you can walk in and speak to afterwards if anything needs adjusting.

Business & Streaming Setups

We also support content creators and small businesses running high-performance workstations — streaming rigs, video editing PCs, and multi-monitor setups that need to stay reliable under sustained heavy load. If you're running OBS, Premiere, or heavy multitasking workloads alongside gaming, we can tune your system and diagnose bottlenecks that generic repair shops often miss.

FAQs 

1. Where do I bring my gaming PC for repair near Mount Warrigal? PCC Computers' nearest store to Mount Warrigal is at Stockland Shellharbour, Shop 1065, 211 Lake Entrance Rd, Shellharbour NSW 2529, open 7 days. You can walk in with your PC or gaming laptop — no appointment necessary for most diagnostics.
2. How much does gaming PC repair cost? It depends on the fault — a GPU driver issue is a very different job to a failed power supply or a liquid-cooling leak. We diagnose first and give you a clear, upfront quote before any work begins, so there are no surprises.
3. Can you fix a gaming PC that won't turn on or won't POST? Yes. No-POST issues are one of the most common faults we see, and can be caused by RAM, PSU, motherboard, GPU or CPU faults. We run a full diagnostic to isolate the exact cause rather than guessing and swapping parts.
4. Do you repair gaming laptops as well as desktop PCs? Yes. We repair gaming laptop screens, keyboards, batteries, charging ports and cooling systems, and diagnose overheating and thermal throttling issues that are common in gaming laptops.
5. My gaming PC keeps overheating and shutting down — can you fix that? Yes, overheating and thermal shutdowns are one of our most common gaming PC repairs. We check dust build-up, fan and pump function, thermal paste condition, and airflow, and recommend a fix based on what's actually causing the heat issue.
6. Can you upgrade my existing gaming PC instead of building a new one? Absolutely. GPU, RAM, storage, CPU and cooler upgrades are all things we handle regularly, and we'll advise honestly on whether an upgrade or a full rebuild makes more sense for your budget and the games you want to play.
7. Do you build custom gaming PCs from scratch? Yes. We build custom gaming PCs to your budget and use-case, with proper cable management, thermal tuning and stress-testing before handover — not just parts bolted together.
8. How long does a gaming PC repair take? Most diagnostics are completed same-day or next-day. More involved repairs — such as motherboard-level faults or parts that need to be ordered in — will be quoted with a clear timeframe upfront.
9. Do you offer any warranty on gaming PC repairs? Yes, repairs are backed by a warranty on both parts and labour. We'll confirm the specific warranty period for your repair at the time of quoting.
