I am usiing Dell Inspiron 5521 i5 with 1GB 7670 Raedon Graphic Card.
Few days back somehow my Raedon driver stopped working. I tried to reinstall it but in the middle I got the error that "Install manager has stopped working". Then I tried to uninstall it properly, and then reinstall it but the problem persists.
I even use CCleaner and GURU app (DDU) but I am still facing the same problem.
