If the system fails to boot due to an unstable BIOS setting, forgotten password, or hardware mismatch, you must reset the Complementary Metal-Oxide-Semiconductor (CMOS). Turn off the PC and unplug the power cord from the wall.

Before installing a Haswell Refresh processor (e.g., Core i7-4790), verify that your board is running the latest BIOS version. Older BIOS versions will cause a black screen with newer 4th-generation CPUs. Graphics Card Compatibility
If your system fails to boot after changing a hardware component or altering a BIOS setting, you will need to reset the BIOS. Locate the 3-pin jumper near the coin-cell CR2032 battery. Jumper caps pins 1 and 2.
