Your computer is slow, it's freezing, or it just doesn't feel as snappy as it used to. Your first instinct might be to buy a new one. But before you spend $800-$1,500 on a replacement, let's talk about something retailers don't want you to know: most people don't need a new computer—they need a repair and optimization.
We've helped over 1,100 customers discover this truth, and they've left us 5-star reviews because fixing their existing computer was the smartest financial decision they made. Here's how to know if repair or replacement is right for you.
Repair with SSD upgrade: $300
Replace with new computer: $1,000+
You save: $700-$1,400
Here's what most people don't realize: your computer's slowness isn't usually because it's old—it's because it's not tuned properly.
When you buy a new computer from Best Buy, Costco, or online retailers, it comes pre-loaded with software designed to slow it down:
All of this runs in the background, consuming RAM, CPU cycles, and disk bandwidth. Most people use only 30-50% of their computer's actual processing power because the other half is being wasted by bloatware and poor optimization.
When we service your computer, we don't just fix the obvious problem. We:
The result? Your 5-year-old laptop performs like it's brand new—sometimes faster than it was when you bought it.
The single biggest upgrade you can make to any computer is replacing its traditional hard drive with an SSD (Solid State Drive).

Same laptop with SSD installed:
That's 9 minutes per day saved. Over a year, that's 45+ hours of your life back.
Some retailers sell "refurbished" laptops that still have the original slow hard drives. They might have a lower price tag, but you're getting the same slow experience. When you repair and upgrade your existing computer with an SSD, you're making a smarter investment than buying someone else's hand-me-down with outdated hardware.
Here's something most computer shops won't even touch: optimizing your actual internet connection speed and reliability.
Many customers complain about slow internet, but the problem isn't always their ISP—it's how their computer is configured. We can dramatically improve your internet performance through optimization that other shops simply don't offer.
Your DNS (Domain Name System) settings are like the phonebook for the internet. When you type "google.com," your computer asks your DNS server "what's the IP address for google.com?" If you're using your ISP's default DNS server, it's often slow and unreliable.
Our optimization includes:
Windows has dozens of network settings that impact internet speed. Most people use the defaults, which aren't optimized for real-world usage.
Our technicians configure:
Windows Update, antivirus scans, cloud syncing, and background apps all consume bandwidth. We:
Most repair shops just replace a hard drive or add RAM and send you on your way. They don't have the expertise or commitment to optimize the entire system. At JTG Systems, we understand that a fast computer isn't just about hardware—it's about every layer of your system working together efficiently.
"I was ready to buy a new $1,200 laptop. JTG fixed and upgraded my 6-year-old Dell for $280. It's faster now than when I bought it. Worth every penny." - Sarah M., 5 stars
"Everyone said my laptop was done. JTG brought it back to life with an SSD upgrade. Best $180 I've ever spent." - Michael T., 5 stars
"My internet was so slow, I thought I needed a new computer AND new WiFi. Turns out JTG just needed to optimize my settings. Now it's blazing fast." - Jennifer K., 5 stars

Open Monday-Friday, 12:00 PM - 6:00 PM. Same-day service available for most repairs.
With proper maintenance (regular backups, antivirus scans, occasional cleanups), a well-repaired computer can last 3-5 more years. Modern processors and RAM are designed to last 10+ years. The limiting factor is usually the hard drive, which we typically replace with an SSD that lasts even longer.
For startup time and application launch, yes. For general web browsing, you'll notice about 2-3X improvement. The 20X figure applies to disk read/write speeds. The real improvement you'll notice is how responsive your computer feels—less waiting, faster multitasking.
We'll diagnose it for free and tell you honestly whether repair makes financial sense. Most damage we see (liquid damage, cracked hinges, broken screens) is repairable for $50-$200. Unfixable damage is rare—usually just a completely fried motherboard.
If your computer has a traditional hard drive, yes. The performance difference is the single biggest improvement you can make. It's especially worth it if you use your computer for work, video calls, or anything that requires responsiveness.
Older computers can usually run Windows 11 just fine, as long as they have a compatible processor (Intel 7th gen or newer, AMD Ryzen 1000 or newer). We can upgrade Windows free of charge and ensure your system is optimized for Windows 11 performance.
90 days on parts and labor. If the same issue resurfaces within 90 days, we fix it at no charge. Beyond 90 days, we're still here to help, but warranty is expired.
