I finally got my computer hooked up and checking everything out, i went online and downloaded the driver from nvidia on my 6800 gs video card. i restarted and now i get a not suffeciant power to the video card. i have a http://www.newegg.com/Product/Product.asp?Item=N82E16811129155 case (it came with a antec 450 watt power supply) i run a 3500 amd athlon cpu with a k8n neo4 mobo, 120 g w. hdd, 2 cd's and a floppy, any suggestions (btw i have the fan on low)
