If Sony or AMD Mobile basic driver doesn't solve your problem then you won't find a newer driver since the HD 5000 series is Legacy hardware not supported by AMD anymore with driver updates.
You can either allow Windows via Windows update to install the best compatible driver or download Sony's AMD driver if it is around the same year as AMD Mobile Driver.
You have only 2 last AMD mobile drivers for your HD 5000 Series GPU - 2015 or 2016.
