We recommend removing 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.
Proceed with a BIOS recovery test to latest version with minimum memory installed using a USB flash drive instead:
If no boot, test the system on a minimal configuration out of the chassis. Remove all memory and if no beeps check your warranty options to replace the board.
