Hello,

thank you to take time on my trouble. For your knowledge it seem i have a bad manufactured device. I talk about with nVIDIA and they can't help me more even use new driver all the time without testing discrete electronic GPU with any software.
It seem quartz frequency defect on motherboard only and done some troubles with soft calculation between nvidia GPU and intel GPU on my laptop. Isn't logical but hardware trouble.

Thx for your attention.
Kind regards
