I'm pretty new to all of this so I'm sure there is an easy solution I'm missing. I have a pretty basic Dell Inspiron running Windows 8.1 64 bit and I wanted to upgrade from the Intel HD Graphics 4000 that came with the system. I've uninstalled the Intel drivers, installed the Asus drivers, and installed the card. However, there is no output from the HDMI port on the new card and it doesn't show up in the Device Manager on the Control Panel. I've tried looking in the BIOS for primary graphics settings, but couldn't find anything. The unit has a 300W PSU, which while it isn't huge, I would think would be large enough to run this fanless, low-power card. Any and all suggestions welcome.
