Many problems with NEW Precision 7520 (09.2017)

My new laptop Dell like box with bugs:

1. Trackpoint freeze sometimes. I can't use this for navigation. I try reinstall driver, but without positive result.

2. USB ports scratch all the connectors that are inserted into them:

3. Video fans sometimes very noise. After reboot BIOS reported about problem.
