Comp not working, found a different problem

[The Astroman]

Well, this morning I had an idea, since my PC did not work and the problem was software-based (see previous post "Problem with my pc"), I decided to create a new partition on my disk where I would put my valuable data, or burn it to disk. Now, this morning, I booted my PC using a Linux Live CD (the PC did not shut down abruptly, so I'm pretty sure it's a Windows crash), and it worked and all, except that it didn't see my disk because it wasn't properly plugged in. So I shut down my comp, and plugged in the windows-faulty-disk. But when I booted again, my screen was black, and a "No Signal" sign appeared. I know it's well plugged in, because otherwise it shows a "No connection" sign. I tried with another old screen, and it didn't work either. Could I have fried my graphics card when I went in my PC to plug in the faulty-HDD? How can I check? What should I do? ONE PROBLEM AFTER ANOTHER!!!

Well have you tried to reinstert the graphic card on the mobo? Or check if you have connected the power to ur mobo well cause it does seeem like you have a graphic card problem.

Yes, i tried unplugging the gfx card, and re-plug it in. A little green LED on the bottom of my mobo indicates to me that it gets power, and it's on.
