For a while now I kept having an auto detect entering power save, usually I would restart a few times and it would work. 

Yesterday I came home and the screen was black and the monitor light was green, after moving the mouse it turned orange and had that message again. The screen had never been black with a green light before. So I tried to restart and it never worked. 

I was using the white plug directly in the video card, I tried to use is in the other port on the card, it has two. Then I tried to use the blue plug that goes in the motherboard and I got this message.

Attention: Unsupported Video Configuration Detected 
Action is Required 
This computer has an add-in graphics card, but the monitor is plugged into the integrated video connector. 
To attach the monitor cable to the add-in graphics card: 
1. Shut down the computer 
2. Plug the monitor cable into the add-in graphics card connector...

I then tried to use the blue plug in an adapter for the white one, all I got was the floating self test thing. 

I tried to clean the video card.

I removed the battery from the motherboard to restart, nothing.

So now all I get is the floating selt test or entering power save.

I'm assuming it is the graphics card which is a ATI Radeon, though I don't know which one specifically other than is was an upgrade, but got the pc in Nov. 2010. I'm assuming I won't be able to purchase the same one but would like an affordable, comparable one. But can't get any info on what I can use with my pc. 

Oh, and it updated to Win 10, which I'm not very happy with. I can't even get all the specs on my pc, my account here won't show it. 

As far as my memory recalls:

Memory is 500gb

Processor is an i5, dual maybe?

Ram is 8gb
