My facebook is not working... what should I do?

[Coco]

I can log on to my Facebook but then none of the games work, I can't say anything on there, I can't see what friends are on, I can't see my notifications or messages, I can't like or do anything but I can go to my Home and my profile.. but that is all... i tried making a new Facebook but it wouldn't let me do that either what can I do that doesn't involve downloading something to fix it?? Please help me out!!
other people on this exact computer can get their facebook to work with no problem.. also it hasd been doing this for 3-4 days now and won't work.
I have google chrome instead of explorer... but idk what to do !!! =(
