About These Tools
What are device diagnostic tools? These free tools help you identify the fault type on your laptop, desktop, phone, or tablet before calling for repairs. Most computer faults — slowness, overheating, screen damage, charging problems — can be narrowed down significantly by answering a few targeted questions.
What to do after running a tool: If the result suggests a serious fault (drive failure, GPU issue, severe water damage), act quickly — delays often increase repair cost or risk data loss. For minor faults, our guides walk through DIY options first.

About These Tools
Who These Tools Are For & How to Use Them
Who should use these tools?
These tools are for anyone whose device is behaving unexpectedly — shutting off, running slowly, displaying screen problems, or showing signs of charging or overheating issues. Use them before calling a technician to understand what you're dealing with.
🧭 How to choose the right tool
Start with the symptom closest to your problem: Slow → Slow Computer Diagnosis. Overheating → Laptop Overheating Check. Screen issues → Screen vs GPU Check. Not charging → Charging Port Check. After getting wet → Water Damage First Response.
⚠️ When to stop using tools and call a technician
If your tool result shows hardware failure, physical damage, or a fault that's worsening — book a professional assessment. Delays on cooling issues, charging faults, or water damage significantly increase repair cost and data loss risk.
Common Questions
Frequently Asked Questions About These Tools
Not necessarily — minor results include DIY steps you can try first. But if those steps don't resolve the problem within a day, escalate. Many 'minor' issues are early warning signs of hardware failure.
Answer every question as accurately as possible. If you're unsure about a question, choose the closest option. If results still don't match, call us — phone review is free.
Yes — all tools cover both Windows and Mac hardware unless specifically noted. MacBook-specific nuances (e.g. T2 chip, APFS, Apple Silicon) are referenced in the relevant result explanations.
If your device is shutting off unexpectedly — use the Overheating Check first, then the Slow Computer Diagnosis. Thermal shutdown is often the root cause of multiple other apparent symptoms.
Depends on the fault. Overheating devices risk permanent CPU/GPU damage. Failing drives risk data loss. Devices with electrical faults risk component damage. When in doubt, power off and call us.
Real-World Experience
Most Common Problems We See With These Tools
These patterns come from real repair visits across Melbourne's northern suburbs — the same issues these tools are designed to help you identify.
Computer slower than it used to be
Usually HDD failure, RAM shortage, or accumulated startup programs. We see this in most suburbs weekly.
Laptop shutting off unexpectedly
Thermal throttling from dust buildup is the most common cause. Often resolved with a professional clean.
Screen flickering or showing lines
Can be screen cable, GPU, or driver fault — the Screen vs GPU tool distinguishes these.
Phone or laptop won't charge
Lint in port, failed cable, or damaged port. The Charging Port Check narrows this down accurately.
Device won't turn on after liquid exposure
Power off immediately. Water damage is time-critical — use the Water Damage Response tool at once.
