Screen lights up but has no picture
I dropped my MacBook and the screen went black. It lights up but there is no picture. I plugged it into an external monitor and booted it up the screen appeared but didn't have the username and password boxes. I typed in my UN and PW and it loaded my desktop picture but no Icons or dock. I tried a whole list of key commands to open apps folders and anything else. The only command that worked was the restart command. I'm thinking I may have damaged my hard drive but I still find it odd that the login boxes didn't even show. Weird. Any ideas?
Is this a good question?
