    Okay... I received a barebones P870DM-G, installed an I5-6500 CPU, one 8g RAM stick and the 980MX card that it came with. (330w Power Supply)

    When I power the system the following happens...

    1. Power button and Keyboard lights up. The power light on the front edge of the case goes to solid green.

    2. Screen stays black.

    3. After about 20 seconds, the fans spin up and the power light on the edge of the case switches to blinking amber.

    4. Screen stays black.

    5. After about 30 more seconds, the whole system shuts down.

    Throughout the process, there are no beeps or any other noise except for the fans coming on.

    I have tried the following...

    1. I re-seated every component - Same result.

    2. I swapped the video card out for a (known working) 780m - Same result.

    3. Pulled the CPU. Inspected the socket under magnification (no bent pins), put the CPU back. - same result.

    4. I removed the battery, removed the keyboard, pulled the CMOS battery, held the power button down, left it for five minutes, held the power button down again, replaced the CMOS battery, - Same result.

    5. I tried the above process again but this time I left the CMOS battery out of the machine entirely. - Same result.

    Any ideas?

    So...

    I put the CPU back into the old workstation that PC it came from and it works, so CPU itself is not the issue.

    I have not tried the GPUs in other laptops, however for two different ones to have the same failure seems remote.

    That would seem to leave the RAM and the laptop/MB itself.

    I have moved the RAM to different slots but still the same result.

    The RAM is a single 8g stick stick from an old machine that I don't have anymore (so I can't move it over and test it) but it did work when it was pulled years ago. That said, I think that I may go out and just buy a single 4gig stick of Crucial tomorrow and put it in and see if that changes anything (basically spend $20 to test the problem).

    If that doesn't fix it then I am out of ideas (except for a MB issue).

    Contact the previous owner and ask him about what BIOS flashed?, it seems the BIOS can't recognize the CPU. You mat need to flash the BIOS with stock version or any BIOS supporting 6xxx CPU's. It will be nice f you can test the CPU in different system.

    Good Luck.

    He says that it booted before without issue but doesn't know what bios version was on it.

    And I have tested the CPU, it does work in the old machine that it came from.

    Trying different RAM is a good idea, it could fix the problem.

    Plus if it's not the ram 4GB + 8GB is not a problem to run together.

    That's good to know.

    Right now I am trying to run down a place locally that has the RAM in stock and is actually open to the public for in-store pickup.

    "Good luck" is not in the cards for this laptop.

    I tried the memory swap.. Same result.

    So I pulled the CPU (again) and asked my wife to help me by holding the magnifying glass....

    ... which she dropped... straight into the CPU socket.

    So it definitely has bent pins now (quite a few of them).

    /facepalm

    ~ Anyone have a P870DM-G motherboard that they want to sell?

    You can try to fix the bend pins one by one, not all of them are necessary to make it boot.
