Screen reads at boot up: "Unsupported adapter installed. PC will automatically power down in a few seconds." Hitting the ESC key does nothing? Can't computer to come on?

Hi lsi
That's a cryptic message.
Can you log on to Windows? Does the PC shut down?
Did you recently connect a new external device to your PC?
If not, then something is amiss with a component on the motherboard.
You could try resetting CMOS by opening the chassis. Then remove the CR2032 motherboard battery. Let the PC sit for about ten minutes. Replace the battery.
Boot the PC and see what happens.
