• Front Panel Connections: Double-check that the Power SW cable from the case is correctly connected to the F_PANEL header.
• Test PSU: If possible, test the PSU with another system or use a PSU tester.

8.2 No Display Output

• Monitor Connection: Ensure the monitor is properly connected to the motherboard's integrated graphics output or your dedicated graphics card.
• RAM Seating: Reseat the DDR4 memory modules firmly in their slots. Try booting with only one RAM stick if you have multiple.
• Graphics Card: If using a dedicated graphics card, ensure it is properly seated in the PCIe x16 slot and any required PCIe power cables are connected.
• Clear CMOS: Try clearing the CMOS by removing the CR2032 battery for a few minutes or using the CLR_CMOS jumper (refer to motherboard diagram).

8.3 System Instability / Crashes

• Overheating: Check CPU and case fan operation. Ensure CPU cooler is properly installed and thermal paste is applied. Monitor temperatures using software.
• Memory Issues: Run a memory diagnostic tool (e.g., MemTest86) to check for faulty RAM.
• Driver Issues: Ensure all drivers are up-to-date and correctly installed.
