Troubleshooting
This section provides solutions to common issues you might encounter.
No Power / System Does Not Turn On
- Check Power Connections: Ensure the 24-pin ATX power connector and the 4-pin/8-pin CPU power connector are securely seated on the motherboard.
- Power Supply: Verify that the power supply is switched on and connected to a working power outlet. Test the power supply if possible.
- Front Panel Connections: Double-check the POWER SW header connection on the motherboard.
- Short Circuit: Remove the motherboard from the case and test it on a non-conductive surface (e.g., cardboard box) with only essential components (CPU, one RAM stick, CPU cooler, power supply). This helps rule out short circuits caused by the case.
No Display Output
- Monitor Connection: Ensure the monitor is properly connected to the VGA or HD Multimedia Interface port on the motherboard (or dedicated graphics card) and is powered on.
- RAM: Reseat the DDR3 memory modules. Try booting with only one RAM stick.
- Graphics Card: If using a dedicated graphics card, ensure it is properly seated in the PCIe 16X slot and has auxiliary power connected (if required).
- BIOS Settings: If you have a dedicated graphics card, ensure the BIOS is configured to use it as the primary display output.
System Instability / Random Crashes
- Overheating: Check CPU and case temperatures. Ensure CPU cooler is properly installed and fans are working. Clean dust from heatsinks.
- RAM Issues: Run a memory diagnostic tool to check for faulty RAM modules.
- Driver Issues: Ensure all drivers are up-to-date and correctly installed.
- Power Supply: An insufficient or failing power supply can cause instability.
Slow Performance / Lagging
- Storage: Check the health of your storage drives (HDD/SSD). Ensure the operating system is installed on a fast drive (e.g., NVMe M.2 SSD).
- CPU/RAM Usage: Monitor CPU and RAM usage to identify resource-intensive applications.
- Drivers: Outdated drivers can sometimes lead to performance issues.
- Operating System: Ensure your operating system is optimized and free from malware.
