hi yesterday i build my first pc,i pluged in everthing correctly when i was finished i booted up, my moniter would get no signal, i then removed my video card and i finally got some connection. After intalling vista with my intergrated vido card i decided to plug in my 8600GTS and then after that i would get no connection using either my video card or the intergrated one.I then rememb erd i forgot to install drivers,i then plugged out my card and tried the intergrated one but that still didnt work.....what do i do?
