I have an HP Pavilion dv6 laptop which has a Radeon HD 6620G graphics. Since upgrading my laptop to Win 10 I have been getting bluescreen crashes. Most are DPC_Watchdog_Violation. I am suspecting my graphics driver as the cause. I think it may have something to do with running a second (extended mode) screen from my VGA port. For the Display Adapter I have driver version 15.201.1151.0, which is the latest. I wanted to try the Beta driver, which should be 15.201.1151.1010 according to the "latest-catalyst-windows-beta" page. When I installed the Catalyst beta though it did not change the driver version for my display adapter. How can I get the driver to update to this latest beta and try that to see if the bluescreens go away with that?
