My Gateway GT5458E desktop will turn on, but the power light doesn’t come on (should be blue) & there is no signal to the monitor. The computer powers up, can hear sounds (fan, etc), keyboard lights up, can see light from dvd player, but nothing on monitor & no power light. It did this before but finally came back on after waiting a while to try again, but not this time. Have also tried a different monitor.
Thanks!
