Could use a little more information to be honest. Like, what browser?, can you play video files via Windows Media Player(VLC, or whatever you use)?, can you watch any other streaming service like Twitch...? Also crashing on a game is vague issue. Could be 100 different reasons, depending on what game, what do you have running in the background? Is it a fresh windows install? If not, I hope you meant 8.1 not just 8 with out any updates. Finally AMD stands for..... anyway you get the point. Just need more info...and buy Intel next time.
