Ive had two or three machines come in now with a symptom of boot to black screen and mouse. The mouse functions, but nothing else. I cant get the Task Manager to come up..nothing. Almost like Explorer.exe was removed. Also, oddly, when I look at the Restore Dirs...all the registry stuff was removed from the restore points, so if you try a system restore with Winternals or such, you get the dreaded SYSTEM32/SYSTEM error. I searched, and didnt see anything related to this..any ideas? At this point, backup, wipeout and reload is my only solution.
