Since you didn't hardly post any information to go by the only very important tip I can give you is to download your Laptop's Mobile IGPU driver from AMD Download page and install that one. It will also install the R8 driver at the same time.
You might be installing the latest driver for the R8 that may not be compatible with your R6 IGPU thus the code 43 or BSODs.
But the best thing to do is to download your Laptop manufacturer's Support OEM drivers and install that first to see if everything is working normally. Then try to upgrade the AMD driver for your mobile processor.
