Professional Computer Repair

When your computer breaks down, the last thing you want to do is pack it up, drive across town, and leave it at a repair shop for days. CAH Tech was built around a simple idea: expert computer repair should come to you. As a fully mobile computer repair service based in Northeast Atlanta, we dispatch certified technicians directly to your home or office—so you can stay comfortable, keep an eye on your equipment, and get back to work faster.

What Makes Mobile Computer Repair Different?

Traditional repair shops require you to disconnect all your cables, carry your desktop or laptop to a drop-off location, and wait anywhere from two days to two weeks for a diagnosis and fix. With CAH Tech's mobile service, a technician arrives at your door with a fully stocked toolkit and diagnostic equipment. We assess the problem in your actual environment—which is especially important for network issues, printer connectivity problems, and software conflicts that only appear in specific configurations. Most repairs are completed the same day, often within one to three hours.

Mobile service also means we can see exactly how your system is set up. If your computer is overheating because of poor airflow in your home office, or if a background application installed by your internet provider is causing slowdowns, we spot those issues on-site. A shop technician working on a bench in isolation simply cannot replicate your environment.

Common Computer Problems We Fix

Over four years of serving Northeast Atlanta, we have repaired hundreds of computers across every brand and operating system. The most common issues our customers call about include:

Virus and malware infections remain the number one reason people call us. Modern malware is sophisticated—ransomware encrypts your files and demands payment, spyware silently harvests passwords and banking credentials, and adware floods your browser with pop-ups that make the computer nearly unusable. We perform a deep-scan removal using professional-grade tools, eliminate every trace of the infection, patch the vulnerabilities that allowed it in, and install layered protection to prevent reinfection. We also walk you through the habits and settings that keep your system safe going forward.

Slow performance is the second most common complaint. A computer that took thirty seconds to boot when it was new but now takes five minutes is not necessarily broken—it is often suffering from accumulated startup programs, a fragmented or nearly full hard drive, insufficient RAM for today's software, or a failing drive that is beginning to develop bad sectors. We diagnose the root cause rather than applying a generic tune-up, so the speed improvement is real and lasting.

Hardware failures including failed hard drives, dead RAM sticks, overheating CPUs, and faulty power supplies are diagnosed on-site with professional equipment. We carry common replacement parts and can often complete the repair during the same visit. For less common components, we source parts quickly and return within one to two business days.

Data recovery is one of the most stressful situations a computer owner faces. Whether your drive failed mechanically, was accidentally formatted, or was corrupted by a power surge, we assess recoverability honestly and pursue every available recovery path. We also set up automated backup solutions—cloud-based, local external drive, or both—so you are never in this position again.

Laptop-specific repairs such as cracked screens, broken hinges, unresponsive keyboards, swollen batteries, and liquid damage are handled with care. Laptops require specialized tools and experience to disassemble safely, and our technicians are trained on the major brands including Dell, HP, Lenovo, Asus, Acer, and Apple MacBooks.

Our Repair Process: Transparent from Start to Finish

We believe you should never be surprised by a repair bill. Here is exactly how a typical CAH Tech service call works. You call us at 404-625-9095 or schedule online, and we confirm a time window that fits your schedule—including evenings and weekends. Our technician arrives on time, introduces themselves, and asks you to describe the problem in your own words. That context is invaluable: you know your computer's history better than anyone.

We then run a full diagnostic—hardware tests, malware scans, event log review, and performance benchmarks—to identify every issue, not just the obvious one. Before touching anything, we present our findings and a clear price quote. You approve the work, we complete it, and we test everything thoroughly before packing up. We do not leave until you are satisfied that the problem is resolved.

Our base service fee covers the diagnostic and the first hour of labor. Additional labor is billed in fifteen-minute increments, and parts are priced transparently before installation. There are no hidden fees, no upselling of unnecessary services, and no "we found seventeen other problems" pressure tactics.

Service Areas Across Northeast Atlanta

CAH Tech serves a wide swath of Northeast Atlanta and the surrounding suburbs. Our primary service area includes Buford, Suwanee, Duluth, Lawrenceville, Alpharetta, Johns Creek, Peachtree Corners, Cumming, Flowery Branch, and Braselton. We also serve surrounding communities throughout Gwinnett, Hall, and Forsyth counties. If you are unsure whether we cover your area, call us—we are often able to accommodate locations just outside our standard zone.

Each community we serve has its own character, and we take pride in being a local business that understands the neighborhoods we work in. Whether you are a remote worker in a Suwanee subdivision, a small business owner on Lawrenceville's historic square, or a student at a Duluth apartment complex, we bring the same level of professionalism and care to every call.

Frequently Asked Questions

Do you repair both Windows and Mac computers? Yes. We service all Windows versions from Windows 7 through Windows 11, as well as macOS. We also support Linux for users who need it.

Can you upgrade my computer instead of replacing it? Absolutely. Adding an SSD to replace an aging hard drive is one of the most cost-effective upgrades available—it can make a five-year-old computer feel brand new. We also upgrade RAM, install larger storage drives, and add components like Wi-Fi cards and graphics cards where the hardware supports it.

What if my computer cannot be repaired? We will tell you honestly. If the cost of repair exceeds the value of the machine, we say so and help you understand your options—including data migration to a new device. We would rather give you an honest answer than take your money for a repair that will not last.

Is my data safe during the repair? We treat your data with the same care we would want for our own. We never access personal files beyond what is necessary to diagnose the problem, and we recommend backing up your data before any major repair—something we can help you set up on the spot.
