I ran the Memtest86 for 8 passes and I got no errors.
I have also ran the seatools test which also passed.
I tried to update my Toshiba ODD but I couldn't find any update on the website you gave me or on Download Windows 7 drivers:
The bluescreen appeared twice today and it blamed ntfs.sys and win32.sys. I uploaded another diagnostic in case it might be useful.
