Can you help me with my computer problems?

[Ziggy Meadows]

I am having trouble with my computer on the internet. I sign into facebook, and it gives me a blank page with nothing the border and how many notifications i have. It never loads, but it says the page is loading. Also, I try to get on my favorite Multiplayer games, like habbo, wizard101 etc. But that never loads either. I can't even play games on famous gaming websites. (gamenode, Armorgames, etc.) and I have no idea whats wrong. Im not really great with computers, so I just deleted cookies, emptied the cache, cleared browsing and download history, but nothing worked. What do you think, and how can I stop the problem?
I got my computer less than a year ago, and downloaded google chrome not too long ago. hmm...
