Going straight to boot.ini is a drastic step. There are so many other options that would cause the system to "restart" than that one file.

It could be a re starting error, to which if the user has error checking disabled the message won't be shown. Drivers also cause restarts and well as software updates.
Hardware could also just make it to this point even with an error.

So going to boot.ini just isn't justified.

Also looking at the posting date of the original users its probable that a reply will be made now.
I'm going to add the CP can and leave it to the original OP for a comeback here.
