First, to check that the keyboard and mouse connected. Then check the power electric. Turn and keep the hand near the vents to supply energy or listen here to see if fans are running. They do not die, but not necessarily all at once. It is possible that the party is to provide fire voltage lights that flash still works while others are inactive.
