A repair that works on a shop’s test bench can still fail the moment it’s back on your desk. Your Wi-Fi, your printer, your second monitor, and your accounts are part of the picture. That’s why every Mount Vernon Computers visit in Alexandria ends with testing in the real environment where you’ll use it.
Before we pack up, we check the fix against your actual setup: we print from each computer, test video calls, confirm email sends and receives, check backups ran, and make sure every device reconnects to the network. If something isn’t right, we deal with it then — not after you’ve called back.

What customers say
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
I can’t say enough great things about this computer repair shop! They delivered my PC right to my door, which was such a convenience. From start to finish, the customer service was outstanding — friendly, professional, and incredibly helpful.Read full review
Daryl has always done exactly what needs to be done, for the price quoted, and in the time estimated. He doesn’t take advantage of my relative tech ignorance, and answers all of my questions – even the stupid ones. You can’t go wrong.Read full review
