    I dropped it and now it won't power on. The power button lights up for about 15 seconds and then turns off. During that time the CPU fan starts but not the gpu's. The screen stays black the entire time and it makes no sound. I have tried reseating all the components without luck.

    Any help in diagnosing the problem would be appreciated. Thanks

    Sounds like something is not being initialized during POST. Try reseating RAM and check the other components while you're at it, if you're comfortable with it.

    I had a similar issue with a HP a few years ago, RAM was my first suspect but that wasn't the issue. I managed to fix it by reseating the CPU. Worth a try just reseating the RAM first, then the CPU and GPU. Check any cables too.

    I've removed all 4 sticks of RAM and tried them one at a time in different slots. I've also removed both gpu's and tried them one at a time. The CPU has also been reseated.

    If the screen is damaged and not being detected, would that cause the machine to power itself down? If not then the only thing left I can think of is the motherboard.

    That or one of the components is damaged and it being loose wasn't the problem in the first place.

    No, you would simply get no display on the built-in, with the system still POSTing.

    I guess I'll start parting it out.

    Any of you company reps have any good deals going on? I need to order a replacement asap.

    I want something with a single 1080, 4k screen and i9

    Inspect the processor socket, this happened to me with my clevo p751zm a long time ago. It was after dropping it too, the ihs was delidded and had moved on the die. It chipped a corner of the cpu die too. Luckly, the cpu worked I just had to adjust the processor correctly, I have a feeling your cpu might be fried or loose in the socket. Do the fans spin up before it turns off?

    EDIT: Does the hdd activity light flash in those 15 seconds?

    The NP9877/P870TM is the current gen equivalent to yours.

    Might've just damaged a hdd. Try to remove the HDD's and see if you can get it to boot to bios or just spam f2. If you can get in the bios, then maybe the boot drive is damaged?
