“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!”

Questions from Lorton neighbors
My computer is out of storage. Can you add more?
Yes. We can install a larger, faster drive, add a second drive in many desktops, or set up external and cloud storage for your photos and videos.
Is my computer worth upgrading?
Many computers from the last several years get dramatically faster with a solid-state drive and more memory. If yours isn’t a good candidate, we’ll say so before any work starts.
How long does an upgrade take?
Most drive and memory upgrades are finished in a single on-site visit. Larger desktop upgrades sometimes take a little longer, and we’ll tell you before we begin.
