I have a Amd Radeon hd 6450 graphics card, and I am running windows 7 64bit. In the device manager it is just listing it as a standard vga graphics adapter. I have re-installed the drivers several time, turned off on board graphics in the bios, and a physically pulling it out and putting it back in. All of this has not helped. Has anyone else had this problem and found a solution?
do you have drivers and utilities CD that comes from your motherboard? try to install all.
After hours of digging and searching for my computer box and trying different things to fix this I was finally able to find the CD for the graphics card. I then realized that the computer didn't recognize the dvd drive so I unplugged that while the computer was on and put it back in and that worked. I then was able to install the drivers from the CD and everything worked. It was a long day haha. thanks for the reply!
