After moving a desktop PC to a new location, a technician powers it on and hears one long beep followed by two short beeps, but nothing is displayed on the monitor. The desktop was functioning correctly before the move. What is the MOST likely issue?
There is not enough RAM installed for the computer to post.
The video card is not properly seated or has become disconnected.
The CPU has failed or is not properly seated.
A non-essential peripheral device connected to the computer is malfunctioning.
The beep code of one long beep followed by two short beeps commonly indicates an issue with the video card. As the PC was functioning prior to the move, the most likely scenario is that the video card has become unseated or disconnected. The symptom of no display on the monitor further supports this conclusion. Other hardware issues, such as a failed CPU or RAM problems, would typically produce different beep codes.
