A few days ago my computer monitor quit displaying the image on the screen. I hooked the computer up to a new monitor and it did the same thing. I hooked up a different computer to the monitors and they are working correctly. I hooked up a new video card to the old computer and see if that was the problem. Same result no display. I don't even see the bios screen display. I was wondering what the problem could be and any suggestions would be helpful. Thanks.
