Might need to clear the BIOS settings. Your motherboard has a Debug LED that should help you diagnose the problem. To clear the CMOS settings use the Clear CMOS jumper on the motherboard. You can also unplug the power supply, remove motherboard battery, wait about 30 seconds, reinstall battery, plug in PSU and power up. This should reset the motherboard to default settings.
