Custom PC Service
Expert Repair for Custom-Built Systems
Your custom rig deserves a technician who understands it. Whether it's a gaming powerhouse, a content creation workstation, or a homelab server, we diagnose and repair custom-built PCs with the same attention to detail that went into building them.
What We Fix
From simple part swaps to complex multi-component failures, we handle the full spectrum of custom PC repair.
Diagnostic & Troubleshooting
We identify hardware conflicts, failing components, and performance bottlenecks — even in complex multi-GPU or custom-loop builds.
Component Replacement
From motherboards and power supplies to GPUs and NVMe drives — we source compatible parts and handle the swap with care.
Thermal & Cooling Repairs
Custom loop leaks, AIO pump failures, thermal paste reapplication, and fan replacements to keep your system running cool.
Performance Optimization
BIOS tuning, RAM timings, driver cleanup, and OS optimization to get every frame and every second of render time back.
OS & Software Recovery
Corrupted installs, boot loops, and driver conflicts resolved. We rebuild your software environment without losing your data.
Upgrade Planning & Installation
Ready for more power? We help you choose the right upgrades — CPU, GPU, storage, RAM — and install them properly.
Why Trust Us with Your Custom Build
We Know Custom Hardware
Unlike big-box stores, we understand custom builds — from enthusiast rigs to boutique workstations. We won't void your warranty or misdiagnose the issue.
Local, Hands-On Service
No shipping your PC across the country. We work on it right here in Northern Virginia with direct communication throughout the process.
Transparent Pricing
We'll explain what's wrong, what it costs to fix, and whether it's worth repairing — before any work begins.
Daryl replaced the hard drive on my wife's laptop, and the entire process, including scheduling, was fast, efficient, and at a very fair price. His communication was timely and clear, and the repair was done right. Highly recommended!Read full review
Mount Vernon Computers is my go to computer repair shop every time I have a problem or need help with my computer. Daryl is so nice and professional that you're not scared to ask a question. He has helped me get a computer with motherboard problems repaired and another computer with GPU problems fixed. I got a new computer and needed help so I called them and Daryl was kind enough to do a video call and walked me through my problem and eventually solved it! 10/10 Highly recommend!Read full review
