Follow the troubleshooting steps above to confirm that the power adapter is properly plugged into the ATX power connector for the motherboard. 2. Keep the CPU, CPU cooler fan and a separate RAM display on the motherboard. Remove all USB devices and external cards from the motherboard, including mice, keyboards, card readers, flash drives, external hard drives and external PCIE cards, etc. Remove all cables from the motherboard, including network cables, sound cables and display cables (HD multimedia interface VGA DVI DP). Then try to turn on the computer, if it turns on properly maybe the problem comes from the external devices removed. Reconnect the external devices one by one until you determine which external device or cable is causing the problem. 3. Try to clear the CMOS.
