Has my laptop completely fcked up!? What is wrong with my internet? (Google Chrome)?

[Lula]

This never used to happen. only since yesterday my internet has just completely messed up and i can't use twitter and facebook anymore because when i click on a page it doesnt load and goes blank. And on twitter it wont let me click on trends without the screen going blank and it wont even let me click on tweets. Also ads have been popping up on my facebook and youtube that i cant get off (when i have a pop-up blocker) I have used MalwareBytes to get rid of malware abd spyware, it says that all the malware has been removed but my internet is still the same. I use Google Chrome and have updated to the new version and i have cleared all cookies. I don't know what's happened. Has my laptop completely fucked up?? I don't know what to do! Can ANYONE help me?
