    Well in most games, the nvidia dedicated GPU autodetects it and starts running. In some i have to assign it. The GPU lamp also kicks in. But i never use it while lets say browsing. So, yes, i guess i use both my GPUs, but not at the same time. I dont know if this answered your question?

    The problem might be the switching.
    It may take too much time and doesn't have to happen at the time of the crash.

    Thank you again for your answer axe0!

    But i very very rarely/never "switch" myself, and my previous computer this worked flawlessly.
    Many/most of these BSOD's occur when im in games running in complete fulllscreen mode, for lets say 25 minutes, shouldnt only the dedicated GPU be running then, so that the problem wouldnt be due to the switching; as there is none?

    If i am mistaken, do you have any guidance in how i should proceed to solve it if the switching is the problem?

    Thanks again.

    A quick quote from @essenbe about switchable GPU's in laptops
    The idea of the internal graphics being active on normal tasks and switching to the dedicated graphics on more graphics intensive tasks, is a great idea. However, the implementation of it on all laptops is quite bad. This is a common problem we see here constantly, no matter the manufacturer. If the new drivers for the internal and dedicated graphics do not fix it, I don't know how to help you. The only solution we have ever been able to find is to disable either the internal or dedicated graphics adapter. That usually solves it, because the problem usually lies in the act of switching. So, forcing it to use just 1 adapter eliminates the switching.
    Choose 1 GPU to go with and disable in the settings possibilities for switching.
    So far I know it might be in the settings for switching GPU's.

    Thanks again axe0!
    So you mean i should basically go into device manager and deactivate the integrated intel gpu? (i would like to try to test a game)
    But regardless of if this works as a solution, shouldnt this be a reason to send my 20 day old laptop back?
    I shouldnt just accept having to disable 1 GPU all the time? :/

    Disabling a GPU might cause only more BSOD's, I've seen it very recently.

    Basically change settings so your GPU's won't switch anymore, that should work.

    Alright. I tried setting it so that my dedicated(nvidia gtx880m) ran as the main GPU.
    While trying to press "apply" i noticed loads of glitching etc. I then exited out of the GPU control panel, and figured i'd reopen it and check if the changes were made. Back inside; i noticed it said "automatic GPU selection" (not what we want). As i attempted to change it again, the nvidia control panel crashed. When i then tried to reopen nvidia control panel; following error message appeared "you do not have a screen attached to the NVIDIA GPU".

    I then tried to reboot; only for a BSOD to appear.
    Reset pc into blinking commandline/dos for 15 mins. I reset the computer by pushing button.
    Pc reboots into windows; i try launching Metal gear solid(convinced im now running on my dedicated GPU). The game is very very sluggish and bad performance, so obviously something is wrong; as my dedicated GPU should now be handlign everythign; and it should manage to do so fine.
    The fans then suddenly go max speed; LED's blinking and beeping starts. I shut down computer. Wait couple of seconds, starts it up again, beeping returns; i press reboot. Beeping stopped, fans go back to normal.

    I have no idea whats going on. Is my GPU loose or broken?

    thanks for all the support and help so far!
    hopefully you got some magic dust somewhere

    I guess your laptop has used the Intel GPU which is just not good against the Nvidia GPU.

    Crash is caused by the Nvidia Video driver.

    You installed the drivers from your manufacturer and disabled the nvidia streaker service.
    Problem is most likely the switching between GPU's.

    I do not have any other solution then trying to use only 1.
