I dropped my windows 7 laptop on its side recently and since then booting it up and logging in has taken between 10-30 minutes in normal mode to boot up. When it finally boots up in normal mode all I get is a black screen with the default cursor. I can move the cursor but cannot do anything, I can't even do ctrl+alt+delete so I have to hold the power button which brings up the 'windows wasn't turned off correctly' screen when I boot the thing up again. When I start it in safe mode it boots up and logs in quicker, but still slowly. In safe mode it loads the usual background and toolbar with icons. I have tried opening executable files in safe mode but most don't work. I don't know much about my computer aside from its a windows 7 laptop and any help would be appreciated. Thanks.
