Hello, I am new here as well, but I may have another solution, you mentioned that the PC is brand new. I tend to want to fix things with sledghammers but have you considered restoring the pc using the system restore method that came with the PC? If this is a NEW pc then that should help a lot, as it seems you are getting a lot of issues out of the box, also with an issue like this (and this is from the perspective of a former computer sales person) you wonder what other issues a brand new system would have if you are getting this out of the box. I may have misunderstood a bit as I read this entire thread in about 4 minutes.
Good luck with this.
