BSOD worker thread returned at bad irql

Possibly, and especially so when we're dealing with a brand new system that's unstable on day 1. Your best bet is to just RMA the sucker for a replacement and not have to deal with spending so much time and effort diagnosing this. Ask that the system be replaced and not repaired, as often times you'll go through several repairs before they finally end up replacing the part that's bad. With a replacement it's just one clean fix with a brand new laptop. Tell them what you've told us and they should be compliant.

Good luck, mate.

after 2 weeks no bsod here it comes again

Not very conclusive, but blamed your nvidia drivers or an issue with your graphics controller. I still stand on my previous recommendation to use your warranty and replace the system.

You may still want to post in your own thread, since just because you have similar symptoms doesn't mean it's the same cause. Though, if it's a new system already giving you grief, your best option is to immediately assume hardware failure and get with your OEM about a replacement laptop (not repair or parts replacement, but the whole system).
