Visual Editor buttons disappeared on Dashboard

In my dashboard, when I click on a draft (or new post) and try to create in Visual Editor, the buttons in the gray above are gone. Typically it has the bold, italics, link, font color, etc buttons. Typical wordpress dashboard. Today when I logged in, they were all gone except for “paragraph” to change the heading sizes… I can not edit my posts like I am used to doing everyday. I logged into my account on a different computer and it looked totally normal, so I know it is just my computer. Any ideas what happened (or what I did)?? I’m lost on this one…

I hope I explained it enough

thanks,
Sarah
