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.
I have worked with Daryl recently to straighten out multiple computers, photos, and generally try to bring me into the 21st tech century. He is patient, punctual, knowledgeable and very pleasant to work with. Highly recommended.Read full review
Daryl has been my go-to-guy for years. I have always found him to be very responsive and great at diagnosing problems. Recently, I had a hard drive failure on a Friday when I urgently needed my computer over the weekend. Daryl was able to get me up and running until he could install a new drive on Monday. A TRUE PROFESSIONAL! We are fortunate to have him in our neighborhood.Read full review
Great experience working with Mount Vernon Computers. They were helpful and understanding regarding my data recovery issue and had more reasonable prices than other shops in the area.Read full review
