Your computer has just abruptly shut off, and pressing the power button doesn’t restart the system. There are no fans spinning or lights on, and no messages appear on the display. Which of these would be the most likely cause of this issue?
A) The BIOS is configured with a startup password
B) The power supply is faulty
C) The LCD display backlight has failed
D) The master boot record is corrupted
E) You really didn’t need to upgrade that garrison
