Sorry, my English not good.
To day I've upgraded windows 7 ultimate to windows 8 CP. And now I have problem with internet browser (IE & Firefox), the image, & flash couldn't load. How I could fix it?
On Firefox, go to: Options/Advanced Tab In Browsing, untick "Use hardware acceleration when available".
I had the same problem, I though that was because of my GPU drivers, but it was just this option.
