    Can someone tell me what could be the problem, photo below. Obviously, it starts with booting, so I suspect it's something with GPU or display. Notebook shuts down when Windows starts loading.
    Thank you

    Yes, infact, the whole display changes colors, transparent green or yellow. Flat cable?

    Could be a poor video cable connection at the LCD with a reseat being the fix, at least that's most common. In rarer cases, the cable needs replaced altogether, and rarer still the problem is the LCD itself.

    Came back from repairs, PMIC on the board was replaced and notebook image on display is now OK.

    Strange thing is that the GPU now after few minutes running goes to 99% usage and the temps go up. Nothings running, on desktop is shown. Anyone have an idea.

    I'm surprised that kind of work was done. Typically the board is just replaced in that scenario, while the defective one is sent out for reworking.

    That is what I have been told. Are you talking about the Main Board? How can I check this? Any suggestions for the GPU?

    Yes, the main board/motherboard. You can see if the serial number is still the same (match it with the NK serial on the bottom of the system, or its original box if you have it).

    Have you looked at running processes & applications in Task Manager? Anything there using hardware acceleration (such as a web browser with several tabs open)?

    Seems like it was nothing. I just turned it on after a couple of days to try again, for some reason ended up in BIOS, not even sure why anymore. Haven't changed anything there but notebook working now perfectly normal now.
    Thanks for helping though.
