Slow computer? Virus infection? WiFi problems? Call or text for honest local computer repair, troubleshooting, and custom built PCs without the runaround.
Practical help for common computer problems, upgrades, and everyday tech issues.
Hi, I’m Justin, the person behind JMG Computers. I’ve been helping local customers with Windows-based computer problems since 2005.
When you call or text, you’re speaking directly with me — not a call center or a big box store.
My goal is simple: fix the problem correctly and give you honest advice without pressure.
Not all computers are built the same. Many store-bought systems look powerful on paper but cut corners in areas you don’t see.
Store-bought systems can look powerful, but often use tighter layouts and lower-quality components that limit upgrades and long-term performance.
Custom builds focus on real performance, better airflow, and standard parts that are easier to upgrade and maintain over time.
I can help you compare store-bought and custom systems based on what you actually want the computer to do.
Contact MeIf you want to know more about how I work, what my workspace looks like, or what the process is usually like when you bring in a computer, these pages and sections give you a better look behind the scenes.
Take a look at the real workspace where I diagnose issues, repair computers, install upgrades, and test systems.
See My Workspace →Browse simple troubleshooting articles and computer tips covering common problems people run into at home or at work.
Read Help Articles →See how I usually handle diagnosis, recommendations, repair work, and final testing so you know what the process looks like.
See the Process →I try to keep the process straightforward so you know what is happening with your computer and what the next step is.
I’ll ask what the computer is doing, what you’ve already noticed, and what you want it to do better.
I check the system to narrow down the issue and figure out whether the problem is hardware, software, performance related, or a combination of things.
Once I know what’s going on, I can recommend the most sensible next step, whether that’s a repair, upgrade, or replacement.
The work is done at a dedicated bench with the tools, testing equipment, and care needed to correct different systems for troubleshooting.
Before a system is returned, I do a final check to make sure it is working the way it should.
Real feedback from local customers who wanted honest help without pressure.
“What impressed me the most was Justin's quiet, calm, confident and knowledgeable demeanor. He's not a sales guy or pushy, but knows his stuff. Very fair price and professionally attired. I highly recommend him.”
“Justin was friendly and very professional. He did exactly what needed to be fixed. I would definitely recommend him because he will get the job done and give you 100% satisfaction.”
“We are very happy with Justin's service and the timeliness with which it was delivered. Justin is a godsend to housebound, barely computer-literate, and budget-conscious people.”
“It's hard to believe that a year has almost passed from when you built the two desktop computers for us. They are working great and no issues at all. Thank you again!”
“Justin explained the issue clearly, fixed the problem, and didn’t try to upsell me on things I didn’t need. That kind of honesty is hard to find.”
“Fast response, friendly service, and my computer is running like it should again. I appreciated being able to talk directly to the person doing the work.”
“The custom desktop Justin built for us has been reliable, quiet, and easy to work on. It feels like it was built to last instead of just sold fast.”
“I had malware issues and terrible performance. Justin got everything cleaned up and explained what happened in a way that actually made sense.”
Big box stores follow a more standardized repair process, but local service offers direct communication, more flexibility, and honest advice about whether a repair actually makes sense.
Whether the issue is slow performance, malware, upgrades, WiFi, or general troubleshooting, call or text and I'll help you figure out the best next step. If I’m assisting another customer, I’ll get back to you as soon as possible.
