The Radeon HD6300 has been moved to legacy status, there are no new drivers available for it. The Crimson 17.6.2 is not compatible with this product.
I would suggest you do a complete uninstall of the display drivers and then use the driver selector here to download the last available drivers for your product: www.amd.com/drivers
Never use the 'minimal' setup. Always use the full package.
Win10: parameters - system - power and hibernate - additional parameters - adjustment - change additional parameters - switchable graphic adapters - set maximum.
