Win 8 Release candidate 8400

Related to your classpnp.sys (SCSI Class System Dll) driver. I would start with checking all the cables, connectors, drives etc.

Old driver needing update

How To Find Drivers:
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

- - Driver manufacturer links are on this page: Drivers and Downloads

I would also run a system file check to verify the OS files

SFC /SCANNOW Command - System File Checker
