Computer diagnostics
Find the cause before spending money on the fix.
Good diagnostics answer a specific question: what is actually failing? We use the symptoms, failure pattern, and targeted testing to separate hardware faults, software problems, thermal issues, and configuration problems.
What we do
Diagnostics for difficult and intermittent computer problems
A freeze can come from memory, storage, graphics, power, thermals, drivers, or the operating system. The goal is to narrow that list before parts are replaced.
Common symptoms
When a diagnostic is worth it
- Random shutdowns or freezes
- Computer will not boot or POST
- Blue screens and repeated crashes
- Slow performance with no obvious cause
- Black screen or intermittent display problems
- Hardware works sometimes but not consistently
- Problems return after a Windows reinstall
- A part was replaced but the issue remains
Diagnostic approach
Testing may include
Memory testing, slot isolation, and configuration checks.
SSD or hard-drive health and file-system checks.
CPU and GPU stress testing with temperature monitoring.
Power, charging, and load-related behavior.
Windows system files, updates, drivers, firmware, event logs, and crash patterns.
Component isolation, cabling, seating, and visible damage.
How it works
A clear path from symptom to solution.
Testing, authorization, and validation keep the work tied to the actual problem.
Document
Record the exact symptom and when it occurs.
Prioritize
Start with the most likely and least invasive causes.
Reproduce
Stress or isolate the system as needed to expose the fault.
Recommend
Base the repair recommendation on what testing supports.
Questions & answers
Useful answers before service begins.
How long does a computer diagnostic take?
Simple problems can be identified quickly, while intermittent freezes, thermal issues, and load-related shutdowns may require longer testing to reproduce reliably.
Do you replace parts during the diagnostic?
Not automatically. The purpose of diagnostics is to identify the likely cause first. We discuss the next step before repair work or part replacement.
Can you diagnose a computer that works fine most of the time?
Yes, although intermittent faults can take longer. Details about what you are doing when the problem occurs are especially useful.
What should I bring with the computer?
For a laptop, bring the charger. For desktops, tell us about recent hardware changes and bring any component or cable directly related to the problem if requested.
