Graphics Card Not Dead, Not Working Either

I have fixed a few problems with my computers based on the information here. This is my first post. Last night, while playing Sims 2: Apartment Life, my moniter flickered a black screen twice and then froze. Almost immediately after I got a blue screen of death, however the computer shut off faster than I could read. So, this morning I turn on my computer and nothing. I got the white text and the nice big 'e' for emachines with the Boot and Bios keys listed. Then the monitor went to standby. I turned it off and then back on and tried to get boot settings so I could start up in easy mode - thinking something happened to my drivers, but same thing happened, monitor went on standby.

So, I turned the computer off, opened it up and took a look inside. A little dusty, but everything was plugged in right and I made sure the video card was secure. I took the plug out of the video card and put it in the default on board thingy. Started it up, same thing. So, now I'm thinking, '****, my card died'. 'Cept when I turn the machine on the fan starts up. So, I'm confused. I take the card out and start up the computer and BAM, it works. So, I'm still thinking its a dead card. Well, I try a few things, like uninstalling the old video card drivers, restarting and plugging the card in during restart. WIth the moniter still plugged into default and working correctly, I check Device Manager and what do you know?! It lists my card and starts trying to install the drivers. So I go ahead and reinstall the drivers. Says I need to restart, so I do. Sure enough, the monitor just goes to standby like before. Doesn't matter what I plug it into. So I take out the card, plug it into default, and go into my BIOS. I make sure it's reading my video card from the PCI-e slot and such, which it says it is. So, now I'm just confused......
