“Daryl is a phenomenal resource. He is competent and professional, but very personable. He has never shamed me for my occasional (OK, frequent) ignorant questions about my software nightmares. He just patiently explains the concept and informs me of my options. He then works with blazing speed and before I know it, I am back in business. You will not be sorry if you use his services.”

Common computer repairs
Hardware diagnostics & component replacement
We diagnose and replace failing hard drives, power supplies, fans, and other internal components to get your system running again.
Screen and keyboard replacements
Cracked screens and dead keys don’t mean you need a new laptop — we source quality parts and restore your machine to full working condition.
Slow computer diagnosis & speed-up
We identify what’s causing sluggishness — startup bloat, aging drives, low memory, or hidden malware — and apply targeted fixes to restore speed.
Operating system issues & recovery
From failed updates to corrupted system files, we handle clean installs, restores, and recovery while preserving your personal files.
Crash and blue screen troubleshooting
We use diagnostic tools to pinpoint the cause of freezes, restarts, and blue screen errors — whether it’s hardware, drivers, or software conflicts.
Power and charging problems
Won’t charge, shuts off randomly, or won’t turn on? We test and replace batteries, charging ports, and power supplies to get you powered up.
Software installation & updates
We install the programs you need, remove the ones you don’t, and make sure your applications, patches, and drivers are current and working.

What customers say
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
My teenager did not properly back up her laptop. So, when it totally crashed she lost access to her English final and all her junior year school files. In a panic we called Daryl on a Sat morning. He was able to retrieve all her files and make them available for use on either a PC or Mac. We have both and were not sure which computer would be used to finish up the school year. We had the all her files by 6pm that same Sat. You will not go wrong with Daryl. His prices are reasonable and we found him knowledgeable and honest. We will be using Daryl again for any future problems.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
