If you have a .dmp file...BlueScreenView should have picked up the data contained.
The .dmp file should be in the Windows/Minidump folder...can you check the location and see if it's there?
Also...right-click on My Computer, select Properties, select Advanced tab. Scroll down to Startup and Recovery, click Settings. In System Failure section, make sure that the first two options are checked, with the third unchecked.
I would try to run sfc /scannow, on the premise that system files may be damaged. This command will replace any damaged/missing system files.
Note that this command must be conducted with a CD having the same SPs installed...as the system currently has installed.

System manufacturer and model?
