Diagnosis, module replacement, and trusted board-level referrals.
We are the highest-rated computer company in Niagara.
Most repair shops tell you to replace the motherboard when it dies. At JTG Systems, we start with a thorough diagnosis. We replace any failed modular parts when possible, and if the fault is on the logic board itself, we refer you to a trusted board-level specialist.

A laptop motherboard contains thousands of components. Often the real problem is a replaceable module around the board—a DC jack, a charging sub-board, or a daughterboard.
We provide honest motherboard failure diagnostics for dead laptops, often recovering data and functionality that other shops claim is "impossible."
We diagnose these issues on Apple, Dell, HP, Lenovo, Acer, ASUS, and MSI devices.
Laptop shows zero signs of life. No lights, no fan spin. Often caused by a failed power rail or mainboard fault.
Coffee, water, or soda spills cause immediate corrosion and short circuits. Time is critical for recovery.
A failed component on the mainboard can stop a premium laptop from turning on. We diagnose the fault and explain your options.
Failed updates can 'brick' the device. We diagnose BIOS issues and advise on replacement or recovery options.
The laptop works (external display is fine) but the screen is black. The backlight circuit may be faulty. We diagnose and refer board-level faults.
Distorted video, lines on screen, or crashing during games. The graphics chip may have failed. We diagnose and advise on board-level referral.
We inspect the device and any accessible modules for visible corrosion, burns, or physical damage.
Using factory boardview files and schematics, we trace voltage lines to locate where the power stops.
When safe, we use thermal cameras to identify overheating components that point to a short or failed part.
If a replaceable part (DC jack, daughterboard, battery, or sub-board) is at fault, we install a quality replacement.
When the fault is on the main logic board, we coordinate with a trusted board-level specialist and explain the options.
We test the device after any replacement to confirm power, charging, and basic functionality before return.
