Falls Church homes and small offices keep computers running longer than most, which means parts eventually wear out. If yours is clicking, shutting off or refusing to power on, we test each component to pinpoint the cause.
We come to homes in Falls Church City, Seven Corners and Lake Barcroft and to offices along Broad Street. You see what we found and approve the cost before work begins.

Why Falls Church calls us
Repair or Replace Advice
If the repair costs more than the computer is worth, we tell you up front.
No Upselling
We replace the part that failed and leave the working ones alone.
Data Wiped on Request
Old drives we remove can be wiped or destroyed so your information stays private.
What We Check
Broken ports and jacks
Loose USB ports, a broken HDMI jack or a worn charging port can be repaired or replaced on most models.
BIOS reset and updates
When the computer stops at the logo screen, the BIOS may need a reset or update. We handle both carefully.
Failing hard drives and SSDs
We scan the drive for bad sectors and errors, copy your files off a failing drive and install a new SSD.
Power supply repair
Desktop power supplies wear out over time. We confirm the failure with a tester and install a quality replacement.
Logic board diagnostics
We isolate motherboard faults from other parts so you know whether the board itself has failed.
Memory testing
Faulty memory causes crashes and freezes. We test every module and replace or add memory as needed.
Noisy or failed fans
We open the case, clear out dust, replace noisy fans and confirm the processor stays cool under load.
Video card testing
We check the graphics card under load, update its drivers and replace the card when the hardware has failed.
Small office hardware in Falls Church
A single failed computer can slow down a small office. We test the failing machine, swap the part on site when we can and check the other office computers for the same warning signs, such as a drive that is starting to report errors.

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
