Package List: 1 x X79 F1 Motherboard (Appearance color random)1 x SATA Cable1 x Baffle Note: Does not turn on:When pressing the power button to start the computer, the fan and Q LED indicator/QCODE do not respond, please follow the instructions below to troubleshoot1. Follow the troubleshooting steps above to confirm the power supply of the motherboard to confirm whether the power adapter is correctly plugged into the ATX power port2. Keep the CPU, CPU cooler fan and a separate RAM 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. Remove all cables from the motherboard, including network cables, sound cables and display cables (High Definition Multimedia Interface/VGA/DVI/DP). Then try to turn on the computer, if it boots normally maybe the problem is with the removed external device. Reconnect external devices one by one until you determine which external device or cable is causing the problem3. Try clearing the CMOS
