I also tried to unplug the power cable multiple times but pressing the power button was only turning the light on case on and nothing else. Then I went sleep and the day after I was able to turn it on. This thing is crazy, I'm quite sure it's the motherboard. I even reinstalled Win10 from scratch but it didn't help, it must be a hardware problem. Right now I can't run any game, it crashes after few minutes.
So I contacted Dell and told them what's happening and they said I'll get a new machine since it's not clear what the problem is. I assume they will take their time to find it out. The technician was very kind and told me that someone will get in touch with me today via email. So now I just hope to get new PC asap since I already waited 6 weeks to get this one. Thank you anyway for all your suggestions.
