Sounds like a theme or a plugin is causing the problem. Try renaming the wp-content/plugins folder to quickly disable all plugins and then try logging in. Add the plugins back into the wp-content/plugins folder to find the culprit.
If you have access to the error log file (assuming the site is not that busy), then you might find the error message pointing to the ‘bad’ file (plugin or theme).
Try this tutorial on the ‘white screen of death’: http://www.wpbeginner.com/wp-tutorials/how-to-fix-the-wordpress-white-screen-of-death/ . (Good site for learning.) Their instructions include temporarily disabling plugins, and then trying a different theme (by renaming the theme you are using in wp-content/themes ). Usually the theme or plugin.
Good luck.
