Here’s a concise overview of Hardware Diagnostics for computers and laptops, including what it is, how it’s done, and how companies like Daakshika Infotech or local services typically approach it:
🔧 What Is Hardware Diagnostics?
Hardware diagnostics is the process of testing and analyzing the physical components of a computer to identify hardware-related issues, failures, or signs of wear. It helps pinpoint which part of the system is causing problems such as freezing, crashing, slow performance, overheating, or no boot.
🧩 Components Typically Diagnosed
| Component | Common Issues Detected |
|---|---|
| Hard Drive / SSD | Bad sectors, failing disk, read/write errors |
| RAM (Memory) | Faulty or unstable modules |
| Motherboard | Faulty capacitors, chipset issues, short circuits |
| CPU | Overheating, thermal throttling, failure |
| GPU | Artifacts, driver issues, overheating |
| Power Supply | Voltage drops, inconsistent power |
| Cooling System | Fan failures, clogged vents, overheating |
| Battery (Laptop) | Wear level, charging issues |
| Keyboard/Touchpad | Unresponsive keys or cursor |
| Ports (USB, HDMI) | Physical damage, non-detection |
🛠️ Diagnostic Tools Used
- BIOS/UEFI Diagnostics
- Built-in tools in Dell, HP, Lenovo, etc.
- E.g., HP PC Hardware Diagnostics
- Third-Party Software
- CrystalDiskInfo (disk health)
- MemTest86 (RAM errors)
- HWMonitor or Speccy (temperature, voltage)
- OCCT, FurMark, Prime95 (stress testing CPU/GPU)
- Manual Inspection
- Physical damage (burn marks, blown capacitors)
- Loose connectors or worn-out fans
- Multimeter / POST Cards
- Used by professional technicians for in-depth motherboard or PSU analysis.
