New Graphics Card Not Working

[SlyHasStuff]

So today I got a new graphics card and when I took out my old one and put in the new one, I started up my pc and everything turned on correctly except for my graphics card.

I had a GeForce GTX 720 and switched to aa Radeon GTX 460, I put in the installation disc and when I turned it on the fans on the graphics card didn't spin but a little red light came on and all the other fans were working and the lights but my monitor would just go into power saving mode and I double checked to DVI I used for it and even used a dufferent one but it always went straight to power saving mode.

I have a newer pc and it has 8gb tan and met the specs recommended, I don't know much about computers and I'm only 13 but I hope someone can help me out.

Thanks.

uninstall the Nvidia drivers, reboot your system. Then goto http://support.amd.com/en-us/download and find the RX 460 drivers.
install those and reboot your system.
