I got my dell inspiron N511o about a year ago and since then I haven't been able to update my graphics driver. It seems as though a driver update doesn't even exist. When I use AMD Driver Autodetect, it says: AMD Catalyst Mobility cannot be downloaded due to incompatible hardware/software on your computer. The version of your graphics adapter is not supported. Also, when I look through the AMD website for drivers all of them are not compatible with mine. Please help me. Where can I find a compatible driver update?
