char, from what I read on here it sounds like you are having software and not hard ware issues. I would start off with reinstalling the Windows OS. The black screen with a pointer only, as well as all the other errors, seem typically of windows having issues with some of the system files. It is possible that the "fall" of your computer causes some read/write issue on the hard drive. Reformat it when you install windows. Good Luck and I hope this helps. BTW the windows explorer issue is not related to internet explorer, those are separate explorer's ;-)
