Troubleshooting a Desktop Computer

Troubleshooting a desktop computer involves checking hardware and software to identify and fix issues. Here's a step-by-step guide for basic desktop troubleshooting:

---

🔌 1. No Power / Not Turning On

• Check power cable and wall socket.
• Test SMPS (Power Supply Unit):
  • Use the paperclip test to see if the PSU fan spins.
• Inspect power button connection to the motherboard.

🖥️ 2. No Display

• Check Monitor: Try a different monitor or cable.
• Check GPU (Graphics Card):
  • Reseat the card or try onboard graphics (if available).
• RAM Issues: Remove and reinsert RAM sticks one by one.
• BIOS Beep Codes: Listen for beeps — they indicate specific errors.

💻 3. System Turns On but No Boot

• Check POST (Power-On Self-Test):
  • Look for lights/fan and beep codes.
• Reset BIOS:
  • Remove CMOS battery for 1–2 minutes.

🧠 4. Slow Performance / Crashing

• Check for Malware using antivirus or tools like Malwarebytes.
