Fairfax professionals and George Mason students cannot wait on a laptop that freezes during a presentation or an exam. We find what is slowing your computer, fix it and show you how much faster it starts.
We come to homes and offices in Fairfax City, Fair Oaks and Mantua. Most tune-ups take about an hour, and you approve any upgrade before we install it.

Why Fairfax trusts us
Honest Upgrade Advice
If the computer is too old to speed up much, we say so.
Remote Option
Many software tune-ups can be done over a secure remote session.
Background Apps Tamed
We stop hidden apps from eating memory while you work.
What Slows Computers Down
Extension cleanup
Bloated browsers are a common slowdown. We clean out extensions, cache and unwanted toolbars.
Software updates
We bring drivers and key programs up to date and remove old versions that cause conflicts.
Hardware health check
We finish with a health check of the drive, memory and temperatures so you know the computer is sound.
Startup app review
We review every program that starts with the computer and disable the ones you do not use.
SSD upgrades
Replacing an old hard drive with an SSD is usually the biggest speed boost. We clone everything over.
More RAM
We add memory to laptops and desktops that run short during video calls and multitasking.
Pop-up and adware removal
A full malware scan is part of every tune-up, since infections are a common cause of slowness.
Windows tuning
We adjust Windows settings, clear temporary files and fix issues that drag down performance.
When an upgrade beats a new laptop
If a computer is less than five or six years old, a solid-state drive and more memory usually cost far less than a replacement. We check your model and tell you honestly whether an upgrade will help or whether the money is better spent on a new computer.
What customers say
I and other members of my family have been customers of Mt Vernon Computers for many years. Daryl is trustworthy, professional and knowledgeable. I call him because I know that he responds in a timely manner, and that his advice is honest and in my best interest.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
