In the bios of your computer, under a setting (depends on the bios, but still the same principle) you will be able to configure your computer's display card, you should have two options to choose: the current configuration, being intel integrated graphics and secondly your AMD video card. Assuming it's functioning properly you can enable it.
Afterwards make sure that you have proper drivers installed for it to function properly. (Which is what Adrenalin is for) Radeon software may not work unless it detects that your main display card is the r5mm330.
The bios can be accessed by rebooting your pc and hitting what prompt it tells you that will enter the bios, usually f12 or delete or something to that nature.
In order to figure that out check your motherboard's manual or youtube it.
