More Arlington services →Upgrades for busy Arlington home offices
A lot of Arlington condos and rowhouses double as offices, and a sluggish computer costs real time on every video call. We come to you in Ballston, Shirlington, or along Columbia Pike, check your machine, and recommend the upgrade that will actually make a difference.
We do the work right at your desk and move your files and programs over, so you’re back on calls the same day.
“I thought my Dell was toast. It was fixed in under an hour. Kind, proficient, polite workers. Smart. Knowledgeable. My Dell Inspiron thanks you!”
Most computers slow down because of an aging hard drive or too little memory, not because they’re worn out. Mount Vernon Computers upgrades Arlington laptops and desktops with solid-state drives, more RAM, and current Windows, often for far less than a new computer.
Before we touch anything, we’ll tell you honestly whether an upgrade or a replacement is the better value for how you use it.

Questions from Arlington neighbors
My laptop is slow during video calls. Will an upgrade help?
Often, yes. A solid-state drive and more memory make a big difference for Teams, Zoom, and browsers with many tabs open. We’ll check your model and your Wi-Fi to find the real bottleneck.
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.
Can you upgrade a laptop?
Many laptops can take a faster drive, and some can take more memory. A few models have parts soldered in place, so we check yours first.
