Laptop switches off in BIOS and Windows 10 but not in Linux

Hey guys :)
My Laptop suddenly switched off when the GTX 765m was in use instead of the intel gpu while using Windows 10. I tried several things like cleaning my fan, changing the cmos battery etc. As noone in the internet could help me, I deleted both SSD's to reinstall Windows 10. The problem is, that even in the BIOS my Laptop switches off (because the NVIDIA is in use) and i dont't have enough time to install Windows. So i installed Linux on a USB-Stick an booted the Laptop with it. Luckily that worked, because Linux uses the Intel GPU, and Linux is booted fast enough so that the BIOS isn't "in work" long enough to shut off. The weird thing is, that in Linux I don't have any issues at all. I even ran a Benchmark (unigine heaven) with the GTX and everything worked perfectly fine (just as a evidence that my laptop isn't overheating: the temperature was at 58 degree celsius at its max). So my question is: What causes problems like that in Windows and BIOS but not in Linux?
PS: Sorry for the bad english, but I'm from Germany. But as noone in a German Forum could help me, i post my problem here.
 
Are you sure the problem isn't somewhere else? How did you determine that it must be the NVidia video at fault?
 
Because the problem occurs/occured as soon as the Nvidia was in use. I could work for hours with the Intel GPU, and as soon as I started a game, or did something else that used the GTX I got this problem. Also there was a entry in the protocoll in Windows that (according to the internet) was sign for an overheating GPU.
 
Might just have to send it in to get cleaned out and thermal paste reapplied if its just overheating. Other than that it might had failed on you.
 
As I mentioned above, i did clean the system and renewed thermal paste. And, as I also already wrote, the system is way too cold for a switch off due to overheating

Not necessarily, improperly applied thermal paste may not provide sufficient heat transfer to the cooling system in your laptop. It could even be turned into an insulator between your heatsink and the gpu. Temps can spike really quickly if that happens.

However, I'm trying to understand your problem here. Is your computer turning off completely (screen goes black and power for everything turns off) as soon as your laptop switches power to the Nvidia gpu? Or does it give you a hardlock, bsod, or any other kind of crashes?

What laptop do you use?
 
As the problem always takes the same amount of time to occur in BIOS an didn't come up even after a long time of GPU use in Linux i don't think that I made a mistake.

The Laptop simply switches off, it's not like turning it off in a "normal" way. But when i ran Windows there was no message or something like that when I turned the Laptop back on as it gets shown when you suddenly stop energy supplie or get a blue screen or something like that. Also the power supplie can't be the problem as i have the issue when i have the Laptop plugged in, as well as when i use the battery or both. Additionaly this would also be the case in Linux and not only when Nvidia is in use.

I have an Schenker XMG A503
