Gaming PC Repair and Custom Builds in Nashville
Thermal Paste and Cooling — Stop the Overheating
Heat is the enemy of gaming performance. When your CPU or GPU hits thermal limits, it throttles — dropping frame rates and causing stutter. The most common cause is dried-out thermal paste, which should be replaced every 2–3 years. Our thermal service ($79+) includes removing old paste, applying premium thermal compound, cleaning fans and radiators, and verifying temperatures under load. If you're running a water-cooled system, we also check pump function, inspect for leaks, and refill or replace AIO coolers as needed. After our thermal service, most customers see 10–20°C lower temperatures and noticeably smoother gameplay.
GPU Installation and Graphics Card Upgrades
Upgrading your graphics card is the fastest way to boost gaming performance. We install new GPUs, including removing the old card, fitting the new one, connecting power cables, updating drivers, and testing performance. GPU installation starts at $149 and is typically done same-day. We also troubleshoot graphics card issues — artifacts, driver crashes, black screens, and overheating GPUs. If your current GPU is failing, we can test it and recommend a replacement that fits your case, power supply, and budget.
Custom Gaming PC Builds
Want a custom gaming PC built to your exact specs? We handle the entire process — from recommending compatible components to assembly, cable management, RGB setup, BIOS configuration, and stability testing. Bring us your budget and the games you want to play, and we'll design a system that delivers the frame rates you need. Build labor starts at $149 (parts priced separately). We also handle partial upgrades — adding more RAM, swapping in a faster NVMe SSD, or upgrading your power supply to support a new GPU.
Water Cooling Installation and Repair
Water and AIO cooling systems keep high-end gaming PCs running cool and quiet, but they need maintenance. We install new AIO coolers and custom water cooling loops, replace failing pumps, fix leaky fittings, and refill coolant. Water cooling installation starts at $129. If your AIO is making noise, not cooling like it used to, or showing signs of pump failure, bring it in before it fails completely and takes your CPU with it.
Performance Optimization for Gamers
Sometimes your gaming PC isn't broken — it's just not optimized. Our performance tuning service ($79+) includes removing bloatware, updating drivers, optimizing Windows settings for gaming, configuring your GPU control panel, and benchmarking before and after. We can also help with game-specific settings, monitor refresh rate configuration, and G-Sync/FreeSync setup. Many customers are surprised how much performance they're leaving on the table.

My gaming PC keeps overheating during games. Can you fix it?

Our thermal service ($79+) includes cleaning, fresh thermal paste, fan inspection, and airflow optimization. Most overheating fixes are done same-day.
Do you build custom gaming PCs?
Absolutely. We design and build custom gaming PCs tailored to your budget and games.

Can you fix a custom PC that won't POST after I built it?
Yes, this is a common issue for first-time builders. A PC that won't POST usually has a motherboard standoff short, incorrectly seated RAM or GPU, wrong BIOS settings, or a DOA component. We diagnose the problem, fix the issue, and get your system booting. Most POST troubleshooting is completed same-day.
Do you repair prebuilt gaming PCs like Alienware, CyberPower, iBUYPOWER?
Yes. We repair all prebuilt gaming desktops including Alienware, CyberPower, iBUYPOWER, NZXT, Origin, ABS, and HP Omen. Common prebuilt issues include proprietary power supplies that need adapters, limited upgrade space, and thermal problems from factory cooling. We know these systems inside and out.
Can you make my gaming PC run faster without buying a new one?
Often yes. A performance optimization ($79+) includes cleaning out dust, replacing thermal paste, updating drivers, optimizing Windows for gaming, and removing background bloatware. Adding more RAM or a faster SSD can also dramatically improve frame rates. We benchmark before and after so you can see the improvement.
