Stealth rz09-03100em1 only loads windows the second time you turn it on

Hi. Recently, my laptop always switches itself off again after switching it on, if I start it again, it loads Windows normal. If it does start the first time, it mostly turns itself off at the log in screen. Exactly the same when I close the screen, when I open it it starts for 2-3 seconds and then goes off. As long as I'm using it everything is fine, if I don't do anything it's off after a while too. I change the SSD and Updated the bios to version 1.05, no change. What can it be, anyone have the same issue? Grüße Steven
