I just got an nVidia GeForce GTX 460 for Christmas. I plugged it into my computer but it never detected it in the device manager. I've installed the drivers and uninstalled the previous video card's drivers (nVidia Geforce 6150SE) but still nothing. I have a an HP Pavillion a4310f with all the default components besides the video card. I seriously need help with this, that's an expensive video card and I can't let it go to waste.
