    It could be a faulty board but I would try the Extended clear that I mentioned above with clear cmos via jumper PSU power cord removed and cmos battery removed. Leave it like that for 5 min then try, if not let it sit longer up to 1hr or even upto 24 hrs. Also may want to try re-seating the cpu or look for bent pins.

    Koen, did you figure this out? I have the EXACT same problem and your video confirmed it. The mobo as completely fine until I introduced a second monitor and then poof, it wouldn't boot after that. Prior to this the little voltage meter would read out the number beautifully and the internal power button actually worked. I've already tried everything presented on your post including switching out the PSU, no luck yet. If you solved it without replacing the mobo please let me know. Any response is much appreciated. Thanks.

    Hey man. Unfortunately I needed a new PC asap so I bought a new board (a trusty ASUS board) which did work and left this one to get dust on under my bed, so no I didn't fix it, unfortunately. Sad to hear other people have the same problem. I suggest you RMA it, go to a local PC Shop or buy a new board like me.

    Good luck anyways!

    Too funny. A hard reset likely all needed with board out of case and minimum hardware. Guy should have bought a dell :)

    I have a GA-z87x-ud3h with the exact same problem. My PC was actually running smoothly for 20 minutes before it crashed.

    I purchased a second one, which looks like it also has the exact same problem.

    I am about the send my CPU away as I think that is the last thing that can be wrong.
