I only asked those questions to see if it was still under warranty and had not been voided.

Due to the number of issues you are experiencing, it may not only be the hard drive (but likely to be).

If I was you I would struggle through with support to get it swapped out.

You will need to push them for a swap out, and complain more about the menus locking up and not being able to reboot.

That should keep them off chasing signal strength issues (BTW 98 is quite high).
