Ok so I apparently live in a dusty environment and I know this, so I started (this is really the first time since I took it into work where a veteran unhooked everything initially) shutting down the computer, opening it up and removing all of the dust from the video card. Its performance actually suffers a bit after a time so I clean it out. I did so again tonight, plugged it back up and reconnected the only plug that was connected to it which was coming from the PSU, or at least the only plug I saw. Is there something else I'm missing? It's quite a bit frustrated because I've been scouring the thing for a couple hours now and haven't turned up a damn thing. Please help ASAP.
