I have an amd a6 5400k apu. Months ago I am using a nvdia gt 630 graphics card and I have some problems on that video card . And now im trying the built in card. But im wondering at the device manager in the display adapter category, beside the amd 7540 hd (built-in video card) it has a yellow exclamation. Others recommended that I will update the driver using the downloadable driver in the website and I downloaded it but the problem is that while im installing it suddenly stop and give an error message "application install: install package failure" and read some forums and I follow their procedures. Ive deleted/uninstall all the past drivers and reinstalled again. Ive done it 5-6 times but still the error message keeps on appearing. Please help me -_-
