I'm having the hardest time figuring this out and I'm completely stumped! Any help at all would be greatly appreciated.

I have a computer here with Windows Vista on it and it was moved and now the Monitor doesn't get signal, when you turn the monitor and computer on the monitor goes straight into sleep mode (it's been tested on multiple monitors with the same exact thing happening)

The other day I went and bought a brand new video card to see if that would fix it cause I had the thought that maybe it was the video port, but it did the exact same thing after I installed the video card.

What's going on with it?

are the video cards and the motherboard compatable? And did you already have the old video card in there working before and it just stopped recently?

the one that quit working is on the motherboard

Got the help I needed, thanks.
