When you are using your Windows 2000-based computer, your computer may become unstable, it may stop responding (hang), and you may experience one or more of the following symptoms:
  • Your computer may become unresponsive to input from your keyboard or mouse.
  • The screen may become black.
  • All of the processes on your computer may may stop responding (hang).
Note that these symptoms are not specific to any particular hardware, and may occur with any configuration. However, these symptoms are more likely to occur with computers that have multiple Central Processing Units (CPUs) because of the increased concurrency.


This problem can occur because of a code defect in SCSI port driver (Scsiport.sys).
