Why can't I access my Facebook account?

[Alice]

When I enter my email and password onto my lenovo laptop, it almost immediately clears it. When I enter my password wrong however, it goes to the 'password incorrect' page. And when I select my account via google all this ''ng}09fd%^BY*BDY&*^&V B)N*&D{* NDU*" gibberish comes up on the page! It only happens on my laptop. Does anybody else have this problem and do you know the solution?
Forgot to mention, that it has been doing this for a couple of weeks. Thank-you for your contributions so far

Try to delete web browser history and then try it again. Hope it works
