Hello, I have a computer that had been working fine, but recently, when powered on, the monitor says "no signal". I have tried rebooting the computer, as well as trying different monitors that work for other computers, they all say "no signal".
Any ideas how I might be able to fix it?
Thank you!

Is the computer turning on, fans are running and LEDs light up?

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

No recent hardware changes...no recent anomalies when the system worked?

FWIW: No POST - No Video - http://support.gateway.com/s/Checklists/BP...007050376.shtml and Is It My Power Supply - http://www.bleepingcomputer.com/forums/t/169618/is-it-my-power-supply/

Are you using onboard video or an actual video card?

1 ) Try another monitor on the affected computer - this will help to rule out cable issues
2 ) Try another video card (temporarily) to see if it's the video output/card that's damaged.
