Last night, I cleared a bunch of unneeded files and shortcuts off my desktop. One of those was a shortcut to Windows Explorer. I also installed updates to the Microsoft LifeCam software, which prompted me to restart my computer. After restarting my computer, I entered my password, and was shown a blank, black screen. All I could see was the mouse. I've tried rebooting the computer several times, I ran the full spectrum of Diagnostic tests (hit F12 when the BIOS is loading, went to the Diagnostics screen, and ran -all- of those tests), and nothing seems to work. The same thing happens when I open Windows in safe mode.
I am currently running Windows 7 on a Dell Inspiron E1705 laptop. I don't know my system specifications other than that. I don't know a lot about computers, as you can probably tell by the above explanation. The best I can think of is that somehow deleting that Windows Explorer shortcut deleted Windows Explorer? I'm really not sure. The computer was running perfectly fine before I deleted the shortcut and installed the new LifeCam software. Any thoughts?
