    What We Handle

    Failed Windows updates

    Stuck in an update loop or rolled back? We resolve update failures and get your system current.

    Corrupted system files

    We run system file checks, repair corrupted components, and restore system integrity.

    Clean OS installation

    When repair isn't enough, we perform a fresh install while backing up and restoring your data.

    Boot & startup failures

    Black screens, missing OS errors, and boot device issues — we diagnose and resolve them all.

    Windows & macOS support

    We work on all versions of Windows and macOS, including older systems that still need to run.

    Driver conflicts

    New updates can break drivers. We identify conflicts and install the right versions.

    User profile recovery

    Corrupted user profiles can lock you out of your own files. We recover and rebuild them.

    Daryl replaced the hard drive on my wife's laptop, and the entire process, including scheduling, was fast, efficient, and at a very fair price. His communication was timely and clear, and the repair was done right. Highly recommended!

    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.

    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.
