I have a gateway computer. My problem is that the monitor does not display anything when I switch the computer on, even when the LCD indicator is on. It all started when the display started getting shaky and warped, threatening to switch off. I then switched off the computer and then back on again-the monitor came on (at least the indicator was on) but no display. Is this monitor dead? The computer still works properly-I can still play music and switch the computer off using the keyboard keys (not the mouse). Can someone please help.
