How diagnostics work

Diagnostic fee: $65. Once the work has been decided, the full $65 goes toward the repair or service.

  1. Call or text with the symptoms and your device details.
  2. We diagnose the problem and explain what needs to be done.
  3. You decide whether to move forward with the work.
  4. If you approve the job, your $65 diagnostic is applied to it.

If you decide not to proceed, you only pay the diagnostic fee and nothing more.

Upgrade path

If the system is worth keeping, we can recommend SSD, RAM, GPU, CPU, cooling, or storage upgrades.

Optimization path

If the hardware is fine, tuning, cleanup, drivers, and settings may solve the problem without parts.

Replacement path

If repair is not worth it, compare practical new-system and gaming PC options instead.

Diagnostics turn guesses into a clear repair, upgrade, optimization, or replacement decision.
