- Ensure the power supply switch is in the ON position.
- Check front panel connections (power button, reset button) for correct polarity and secure fit.
- Reseat RAM modules and the CPU.
- If the motherboard has diagnostic LEDs, check their status for error codes related to CPU, RAM, or GPU.
5.2 No Display Output
- Ensure your monitor is connected to the graphics card (or motherboard if using integrated graphics) and powered on.
- Reseat the graphics card in its PCIe slot.
- Try a different display cable or monitor.
- If using multiple RAM sticks, try booting with only one stick installed.
5.3 Audio Issues (e.g., Whining from Headsets)
- Ensure the correct audio drivers are installed.
- If experiencing noise or interference, especially with rear audio ports, try connecting your headset to the front audio ports of your case. This can sometimes mitigate electrical interference.
- Verify audio output settings in your operating system.
