The Sims 4 doesn't let me get out once I tab the windows key

@Simtasticgallery  When you or your dad reinstalled the D drive, did you make sure it was fully inserted and secured?  The drive should sit parallel to the motherboard, and it's typically secured with a screw and a standoff.  Please make sure it's not popping up and hasn't been screwed directly into the motherboard—either of these would change the angle enough to potentially cause the problems you're seeing.

If that's not the issue, it's still a good idea to remove the drive, clean the contacts with a microfiber cloth, blow out the socket with compressed air, and reinsert the drive.

If this doesn't help, your C drive has more than enough space for Sims 4 now, even with all current packs installed.  So simply reinstalling to C is a reasonable workaround.
