When I started up the pc this morning, as programs were loading, I received
ALERTS of systems leading to a total crash.
They read as follows:

usbwin32.exe

registry.pif

default.scr

CriticalUpdate.exe

Is there ANY way to salvage this by using any of the CD-ROMs for the pc to
locate these sites and repairing them without losing EVERYTHING ???
The pc is running and seems functional, but I don't know what to do ...
continue or quit ???
Can anyone help me with this ... what are these and what can I do to correct
them.

Thanks for any assistance or suggestions.
