  Troubleshooting Motherboard Introduction to Troubleshooting Motherboard: Motherboard is often called the “heart” of a computer — it connects and coordinates every other component, from the CPU and RAM to storage drives and expansion cards. When it develops problems, the entire system can fail, leading to issues like no power, random crashes, or hardware not being detected. Types of Troubleshooting Motherboard: In a Troubleshooting Motherboard is to be have a Nine types. They are:      1. Check the Power Supply      2. Check the CPU      3. Check the Memory       4. Check the Graphic Card      5. Check the Monitor       6. Test with minimal components,isolating the possible cause      7. Clear CMOS      8. Buzzer to troubleshoot      9. Q&A. 1.Check the Power Supply: Please check if the connection of the power cord and electric socket...

                DISPLAY CONTROLLER INTRODUCTION  WHAT IS DISPLAY CONTROLLER: A display controller in a PC is a component, often an integrated circuit, that handles the process of generating video signals and managing the display output. It interprets display commands, prepares pixel data, and sends the appropriate signals to the monitor to create the visual output. Essentially, it's the bridge between the computer's processing and the visual display. KEY COMPONENTS: 1. Frame Buffer : Stores a full image frame before sending it to the display. 2. Timing Generator (TCON): Keeps the display update cycle in sync. 3. Video DAC or Encoder: Translates pixel data into electrical signals for analog or digital displays. 4. Scaler: Adjusts resolution or aspect ratio to match the display’s capabilities. 5. Overlay/Composition Engine: Combines images, videos, and graphics into a final frame Intel 8279 – display controller diagram: TYPES OF ...
