I've turned on my PC, the lights are on and the fans are running full speed, but there's nothing output to my monitor. What do I do?

Depending on the manufacturer of your PC or motherboard,check to see if there are any debug LEDs near the 24-pin ATX power connector on the right side of the motherboard and see if the LEDs stay lit on a component that they're highlighting.  For OEM PCs, check to see if there are any leds on the keyboard of a laptop or on the power button of a desktop PC that provide flash codes to help diagnose the issue.  Some OEM PCs come equipped with speakers that produce beep codes that work in the same manner as the flash codes.  We recommend contacting us immediately if this situation were to occur for you.
