  If your ECS Motherboard-based PC suddenly shuts down while booting up, it might be due to CPU overheating. Apply thermal grease onto the CPU heatsink and ensure the CPU fan is well-connected with the CPU heatsink. Also, check if the CPU fan is working properly while the system is running. You can also try disabling the Smartfan function in the BIOS settings to let the fan run at default speed by doing a Load Optimised Default.

  If your ECS Motherboard PC experiences start-up problems after prolonged use, consider the following: 1. Clear the CMOS values using the CLR_CMOS jumper. 2. Check the CPU cooler fan for dust. Clean the cooler or replace it if necessary. 3. Ensure that the 12V power & ATX connectors are fully inserted into the motherboard connectors. 4. Remove the hard drive, optical drive, or DDR memory to determine which component may be at fault. 5. Check whether there is any bulged electrolytic capacitor or abnormal component, which could indicate a breakdown of devices connected to the motherboard.
