Problem: Blue Screen error message Stop: 0x00000093 0X00000078

While dialing out with a modem I received a blue screen with the error message:  A problem has been detected and windows will be shutdown Stop: 0x00000093 0X00000078 0x00000000 0x00000000 0x00000000


Solution : Blue Screen error message Stop: 0x00000093 0X00000078

my first step would be to uninstall the modem, then reinstall it with the latest drivers.
what type of model is it?

This is a relatively rare error condition. Most documentation points to a driver problem  so check all hardware drivers starting with the most obvious, the video driver. Microsofts main page recommends general hardware troubleshooting, so use the General Troubleshooting of STOP Messages checklist above.
