Model: Pavilion m7790y
OS: Windows 7(32 bit)
Symptoms: The computer Beeps and Monitor displays, "no Signal" during boot up. The fans and hard drives do turn on.
HP support indicates that this is probably the result of a loose component or internal cable connection but a physical check did not show any problems. Trying a different VGA cable didn't work, nor did using the DVI output to connect to the monitor.
