How it's done

How We Perform Computer Performance Optimization

What our technicians do, what it requires, and how to tell you need it.

1 How It's Performed

When this needs a genuine repair rather than a reset, we run a full diagnostic across the usual real culprits — startup program bloat, a nearly-full or failing hard drive, insufficient RAM for current workload, overheating-driven throttling, and malware — rather than guessing at just one, since slow performance rarely has a single simple cause.

Typical time: 45–90 minutes

2 What This Requires

  • A structured check across the common causes (startup programs, drive health, RAM, temperatures, malware) rather than addressing just one and hoping.
  • Before/after benchmarking so the improvement is measurable.

3 When You Need This

  • Boot time, app launches, and file operations have all gotten noticeably slower over time.
  • The system is fine shortly after a restart but slows down the longer it stays on.
  • Fans run loud and performance drops under sustained use — a sign of thermal throttling specifically.
