Hello
I have a Compaq computer, well cousin's computer. I had unplugged it to take home to reformat it but when I went to hook the monitor up the monitor wouldn't get no power/signal to it. It would stay black and the light would stay yellow (not turn green). I had the computer unplugged for 24hrs, I tried with 2 different monitors, mine and the original compaq monitor. It wouldn't work, I tried leaving it on, to get charged but wouldnt' work. Left it plugged for 2 days and it still hasn't worked. Before I unhooked it from my cousin's house the monitor screen was working but right now its not. Do you have any sugguestions on how to fix this?

Your description isn't exactly clear.

When you say that you tried two different monitors and it didn't work, do you mean:

1). Neither monitor worked

or

2). Your one worked but the original didn't

dude, i had this problem with an old gateway. I tried 3 different monitors, and used the same AGP card. My agp card was shot. im assuming it was working at one point, than it just cashed out, out of the blue. My suggestion is get a new video card.

Like Stasiek said, make sure the power supply is set to the right voltage and listen for any bios beeps during the POST. Also, check that the cable and the video card is connected correctly. Make sure no pins are broke or anything like that. If you can get ahold of a different video card then try that to.
