Here are our recommendations for this issue:
1. Unplug the power cord, remove all non-basic components, connect the power cord back in and try to boot up the system. If problem does not take place, try installing the other components one at the time until you find out which is the conflicting one.
Note: A basic computer configuration would consist of the following: keyboard, mouse, processor, minimum memory, hard drive, video card, and monitor. No other add-in should be installed.
2. Test with DDR3-800/1066 MHz 1.5V to narrow the issue. Disregarding the XMP profile, the processor is not designed to support such frequency:
3. If the problem continues, then, remove the RTC (Real Time Clock) battery and leave it out for 30 minutes. After this period of time, insert the battery back in and turn the system back on; if it displays POST messages, go into BIOS Setup Utility by pressing <F2> during the boot process. Once in the BIOS setup utility, press <F9> to restore BIOS default settings. Reset any customized BIOS settings. Press <F10> to save the new settings and reboot the system.
