DELL XPS 13 9310 ISSUES

  I recently bought a dell XPS 13 9310 model and i can tell you that it has many drawbacks. The first problem is that after 1 week of using it, i have experienced the black screen of death problem. I surf the web or doing something else and suddenly the screen goes black for 10 seconds but the sound is on. For example i am in a skype meeting, the screen goes for 10 seconds off but i can hear the voices of others. I tried everything i saw on the web but nothing changed. 2nd problem, the fans and temperature, when im using the laptop all of a sudden the fans start running  and the temperature is increasing a lot... I thought that this may be a BIOs problem but everything (drivers, bios) is up to date. Lastly, sound crackling. The sound is good but in many cases it does a weird sound and so i can't hear clearly anything. I contacted with dell support and they give me some advices about the black screen but nothing changed. However, i like all the laptop features and it runs very fast. Could you give me any suggestions ? I feel like it need to be replaced
