Aserver unexpectedly shut down as a result of overheating. an alert was sent to the administrator's email address but the administrator was away from the workstation when the alert arrived. which of the following would have been a more effective method for sending the alert notification?

Ihave a singular monitor that is a tv for my computer. recently, i took apart my computer and put it back together. when i put in the hdmi cord and booted the computer to see if it worked, the computer turned on fine but the screen was blue with "hdmi no signal." i've tried everything that doesn't require buying spare parts, any answer is appreciated!
