Monitor gets no signal no matter what

[WiseLoad43]

So basicly here's what happened:

I have a windows vista and recently of this year my monitor randomly gets no signal. And it has been getting worse. We've tried moving the rams around. Bought new cords and adaptors and made sure they were in nice and snug. Yet nothing seems to fix it. Some days the monitor will get signal and work perfectly fine while others when i turn my computer on it gets no signal or it gets a signal then reverts to no signal.

I've tested the monitor itself on another computer I have and it works perfectly fine no issues at all!

{{NOTE: Everything else on the computer works fine. No problems at all.}}

This has been happening for weeks now and I don't know what to do anymore. Any help or evn better and answer to this would be great!

Can you tell us what is your full computer specifications? Also, are you connecting your monitor wire to a graphics card that is installed on your pc or on the onboard graphics? You can check in your bios and see which display is set to load first, it may be set to your onboard graphics if your motherboard has it. Usually when you install a graphics card, the onboard auto disables, but maybe in your case it didnt.
