drive wont boot as primary drive in original computer

When it is the primary drive in the origninal computer, it wont boot (not in safe mode either) I get the blue screen with the text telling me I may have a virus....check the drive connections etc etc.

I would seriously just wipe it then. If it will slave get your son to sit down and decide what he wants to save and then format it.
