So I took my computer over to yomamma's house (which he is never on the forms but thier is a good pic of him pissing his pants) and Hasslehoff looked at my sound card. When I got home. I got everything hooked in and turned it on. They fan is really loud, which has never happened. And thier is no signal. ??? I have a GeForce 7900GS OC . I don't know if its something in my computer or video card. I am lost on this one. I had jball look at it, and he couldn't find anything.
