My HDD died so I ended up getting a new one and installing windows. The graphics and sound were fine before that.
It was a windows 8.1 64 bit install, the same kind that came with my laptop, a toshiba satelline s50a-d.
Windows update does seem to be working at the moment and I'm downloading and Installing the updates but I expect that it will croak soon. I've tried the windows update troubleshooter in the past, but it never helped.
The sound has not been working since I installed windows. It might be a hardware problem, I don't know. But it doesn't work even when I put headphones in the 3.5mm jack. The sounds do show in the volume mixer, it's just there's no actual sound.
I just mentioned these problems because they may be related, but what I actually want to fix is my graphics drivers. I have an AMD Radeon 8610G dual graphics card. I downloaded and installed the driver for it, which is AMD's legacy driver catalyst 15.7.1. I also installed a Toshiba display utility just in case. In the device manager, there is an 'unknown device' and a 'Video controller' with exclamation marks and a message saying that they do not have their drivers installed. I'm sure the video controller has something to do with my problem.
