OP logged on yesterday but has not provided responses to all the unanswered questions and suggestions.
like has the BIOS update been done?
has a fresh install onto the original drive happened, while the new HDD was disconnect?
what about a screenshot of within the case showing the two drives and their cabling?
and this new info about fullscreen mode.
does the screen resolution problem occur simply by connecting the 2nd HDD when just using the PC normally, that is, Word, emails, web browser etc?
or is it only in games (with 2nd drive connected) that the resolution issue is happening?
