Internet is behaving oddly- apps needing internet won't work
My Acer aspire zc-606 is behaving very oddly. Chrome and Firefox won't work (Internet explorer is working). If I call on skype, apparently there's an internet connection problem between me and the other person and IMs won't be sent. Multiplayer servers on Minecraft won't load and singleplayer crashes the game, and another game I have has a connection issue. On other devices the internet is working fine, it's just that computer. Why is this happening and how can I fix it?
Also, the computer is running Windows 8.1 and it seems like it's connected to the internet.
Is this a good question?
