White Screen

Hi! I am hoping someone here can help. My site was working perfectly yesterday. I went on this morning to do 2 posts and when they went live, I went to look at the post and got a white screen. When I typed in the site directly into the browser, I got another white screen.
I quickly updated my plugins (8 of which were “outdated”) and refreshed to still a white screen.
I then upgraded wordpress to 3.9.2 and reloaded, still a white screen.
I then downloaded the theme upgrade “Udesign”, deleted old theme and reinstalled the newer version, still with a white screen and now unable to access back end.

I then called godaddy who tried to disable my plugins, clear my cache and still a white screen. They were able to get me to my admin dashboard but couldn’t help any further from there.

I attempted to restore from yesterday, which I knew was working fine, but that didn’t work.

I then attempted to restore from 2 days ago and still a white screen.

Can anyone help? Thank you!
