    Hello,
    In January 2019 my laptop Clevo P770ZM that i bought at www.xmg.gg in 2015 suddenly died while playing.

    When i tried to start the laptop there were some kind of click noise and nothing happened, so i tried differents thing and noticed that without the Gpu connected ( a gtx 970m) the laptop was able to start but stayed on black screen if i'm correct it's because on those models the intel graphic chipset is not usable.

    Recently I bought a new Gpu to replace the broken one, I got a 980m on ebay for 300 box. After installing it i thought that every thing was working well but 30 seconds after the start of the computer a beep + 3 led start showing and fans start turning full strength telling me that my computer is overheating but that's not the realy the case i think.

    Both the gpu and cpu got new thermal paste and I can put my hand on the heatsink it ain't that hot. I don't know how can I fix this issue here's a picture of my bios for more information.

    The system is not getting a proper signal from the gpu likely due to a vbios issue so is shutting down with an EC panic.

    Wipe down the mxm connector with rubbing alcohol. Use a low lint cloth (most shirts are fine) or a toothbrush.

    Item no longer being sold, can you take a screenshot from your cached page of the item details?

    Don't even know if the probleme don't come from my MOBO because I started the computer without the GPU only my CPU RAM and a Disk in it and got the same issue of overheating with my black screen and the heatsink not even that hot.

    The problem you have is the system is having issues reading the GPU thermal sensor. When you remove the GPU, it's really going to have a hard time reading the thermal sensor.
