Ok, i'm not sure what happened but I have an HP pavilion zt3000. Just tonight the computer froze and so I held down the power button to restart it. Upon restarting, windows begins to start up and the wallpaper is visible but no icons, start bar, anything, Just a big gray error message that say, windows explorer has encountered a problem...same old same old. After clicking any of the 3 options at the bottom, debug, send, don't send, nothing happens! The screen just sits there with the wallpaper and the mouse icon (which does move). I can't access anything, any thoughts? Thanks in advance!
