I have hd 6450 silent/di/ 1gd3/(lp) card and it worked fine untill I installed Panda Global Protection 2014 on my computer. After booting my computer, my card doesn't work anymore-I get message, that computer can't find graphics card information and that AMD drivers are not installed. I'm using Windows 7(64). I have unstalled drivers I was using (ATI Display Driver 13.152 for Win7 32/64, Win8 32/64, Win8.1 32/64) and installed them again, but the problem remained. I have also tried to install other drivers, but nothing solved. Can someone help please
