Cant access my emails

Hi there,

I recently have been having a problem when trying to open my emails. Im able to sign into yahoo but when i go to click on the inbox tab suudenly i get a msg say tab is recovering itself. this keeps happening all the time. I tried the yahoo help and they said delete my internet history and so on. i did all that and defraged the computer but it doesnt help. my mcafee says everything is okay and mailwarebytes also says i have no harmful programs.

Can you help me as this is very annoying???
Thanks eva

P.S.
i am able to open my email on my boyfriends computer so it isnt yahoo i think!!!
