A broken gaming PC can shut down your entire setup — and generic computer repair shops often don’t have the expertise to handle high-performance hardware. MarTech in Kennesaw specializes in gaming PC repair, from diagnosing GPU failures and overheating issues to replacing blown power supplies and failed storage drives. Whether you built your rig yourself or bought it pre-built, we know gaming hardware and we treat your system with the care it deserves.
Gaming PC Repairs We Handle
🖥️ GPU (Graphics Card) Repair & Diagnostics
Your GPU is the heart of any gaming PC. If you’re seeing graphical artifacts, black screens, crashes during games, or your system isn’t detecting your graphics card at all, we’ll diagnose whether it’s a driver issue, a PCIe slot problem, or a hardware failure. We can help you determine whether a repair or replacement is the right call.
🌡️ Overheating & Cooling Issues
Thermal throttling, unexpected shutdowns, and fan failures are all signs your gaming PC is running too hot. We clean out dust buildup, replace dried thermal paste on CPUs and GPUs, repair or replace failing fans, and evaluate your case airflow. Keeping your system cool means better performance and a longer lifespan for your components.
🧠 RAM Diagnosis & Upgrade
Crashes, blue screens, and system instability are often traced back to faulty or incompatible RAM. We test your memory modules, identify failing sticks, and can help you upgrade to faster or higher-capacity RAM to keep up with modern games and applications.
💾 Storage Drive Repair & Replacement
Slow load times, missing files, or a PC that won’t boot can all point to a failing HDD or SSD. We diagnose storage health, recover data when possible, and replace drives with compatible upgrades — including fast NVMe SSDs that dramatically improve game load speeds.
⚡ Power Supply Replacement
A failing power supply can cause random shutdowns, failure to POST, or damage to other components if left unchecked. We test PSU output, identify units that are underperforming or dangerous, and replace them with appropriately rated units for your system’s power draw.
🔌 Motherboard & CPU Diagnostics
When your gaming PC refuses to boot and you’re not sure why, the issue could be with the motherboard or CPU. We run in-depth diagnostics to isolate the faulty component, check for bent CPU pins, failed VRMs, and other motherboard-level issues that can be hard to spot without the right tools.
❌ No POST / Won’t Turn On
If your gaming PC powers on but doesn’t display anything, or doesn’t power on at all, we systematically work through the possible causes — from a dead PSU to a failed GPU to a bad RAM slot — until we find the culprit and get your system back up.
🛡️ Virus & Malware Removal
Malware can cripple gaming performance, cause lag spikes, and compromise your personal information. We remove viruses, spyware, and other malicious software and secure your system so you can game without worry.
🔧 Custom Build Consultation & Assembly Help
Building a new gaming PC or upgrading an existing one? We can advise on parts compatibility, troubleshoot new builds that aren’t posting, and help you get the most performance out of your budget.
Brands & Systems We Work On
We work on custom-built gaming rigs as well as pre-built systems from major brands including ASUS, MSI, CyberPowerPC, iBUYPOWER, Alienware, HP OMEN, Lenovo Legion, and more. Whether it’s an AMD or Intel platform, NVIDIA or AMD GPU, we’re comfortable working with it.
