Did you by any chance install any new drivers? Also could you list the rest of your system specifications? However it shouldn't list Nvidia as your graphics adapter unless you have an Nvidia card installed. Did you install any drivers or swap out graphics cards recently?
You could try to uninstall your graphics drivers and then install the latest ones off the AMD website.
Hope this helps!

When it first asked me to download the driver i couldnt find the proper amd one so i believe i installed a nvidea on accident. I dont know which amd i should install for the powercolor amd radeon i still have the catalyst manager. i also have the nvidea manager which is working over the amd one.
