It looks like you are using the recommended Adrenalin software from AMD, so I wouldn't change that just yet. Instead, I would try to get into the laptop's BIOS and disable the internal graphics card (HD8330) if it's really there to disable. Is there a problem of you doing all graphics with the dedicated graphics card (HD8670M)?
I don't see much in the way of product support for your Aspire E1-422G laptop.
