Can you boot the computer at all? If so:
No installation required.
Double click on BlueScreenView.exe
file to run the program.
When scanning is done, go Edit>Select All
Go File>Save Selected Items
, and save the report as BSOD.txt
in Notepad, copy all content, and paste it into your next reply.
If you cannot boot, you will need your Vista disc to attempt a startup repair.
