If the black screen appears after you log in, try rebooting to Safe Mode from the login screen instead of logging in. You do that by holding the shift key while you click Reboot.
If it works in Safe Mode, it's something you've got installed on your PC causing it to hang/freeze/work slowly. You'll have two fun option from there to get it fixed; clean install (I'd recommend this as a time saver) or troubleshoot and find the app/util(s) causing the issue.
