I just bought a http://www.newegg.com/Product/Product.aspx?Item=N82E16814127390 to be a cheap upgrade for http://www.shopping.hp.com/shopping/data_sheet/px769aa.html I plugged the card in and the computer starts up, the fans start spinning and the lights turn on but nothing comes up on my monitor. I havent been able to install the drivers yet because it says to do that after putting the card in
