I am using an on onboard graphics display/adapter(Radeon HD 7540d) on my amd a6 5400k apu. But I have a problem. Because I installed the latest apu update on the amd website but after that amd catalyst control wont run and giving a massage that no graphics card/adapter inserted or cant be read so I checked on my device manager and I found in the diaplay adapter section there is a yellow exclamation on the side of my card name. And ive reinstalled it several times but the problem isnt solved -_- please help, any advice might help.
