Cannot log in to site in order to edit material

Permalink
I recently went onto my website and wishing to edit something tried to log on using previous entry details. After a short time the entire screen went white, I can view the website but any attempt to log in results in the same white screen. I tried changing the password but had no change. No additional add ons or any other changes have been made and no updates installed, I have absolutely no idea what to do. Can someone please help.
