I was playing Left 4 Dead today, when I heard a pop around my system. Being that I wasn't sure what it was coming from, and there was no change in the game, I kept playing.
However, after the game, I started web browsing and all of a sudden, my two monitors went out. The computer, however, kept running.
I turned off the system and turned it back on, the monitors detected “no video” and remained black. However, the computer itself seemed to turn itself on well. I plugged in a spare monitor, and found the same effect with that one: “no video detected”.
While the desktop was on, I used my laptop to check the hard drives on the desktop through the LAN, everything was intact, I was able to browse through my files and copy them over to my laptop. It didn't seem the PC was deterred in any way asides from video.
I did notice that my “side fan” (attached to the case of the computer) wasn't spinning and creating air. So I opened my computer, airblasted the dust from it so it could spin easily, and then air blasted the rest of the system. I then plugged it in to see if any other fans weren't working. The power supply's fan was working, the video card fan was working, motherboard and side fans were working.
I plugged everything back in, but the same problem persist.
I'm thinking that the video card is the problem, and that it's finally gone bust perhaps due to the fact that the side fan wasn't working properly. However, I am not fully sure about that. Is there anything you can suggest to me? Is it really the video card, or is this a symptom of something else? If it is my videocard, can I save it? Or should I just go and buy a new one?
Let me know what I can do to get my video up and running again. Thanks for any help you can give me!

I'll see if my older computer is a PCI-express. That way I can try placing my old school 256 videocard into the digital storm desktop. But I'm not sure if it's PCI or an older port model. Will try it tomorrow or the day after.
