Mobo issue? Custom build won't start anymore

  1. Hello,

    I just finished assembling my first build. At first it turned on without a hitch, was able to install windows and a few drivers.

    I had to restart a few times, which went fine for the first few times, and then it just didn't boot back up. The power button doesn't do anything, the fans don't start, nothing happens.

    When I jump the psu, all the fans start, so I'm thinking the issue must be with the mobo..

    Here's a list of all the parts I'm using : http://ca.pcpartpicker.com/p/JFVvD3

    Thanks.

    First, are any wires touching that might be causing a short such as a wire touching the back of the mobo? Second, I had something similar happen to me a few years ago with a new build. There is a tried and true though often tedious way that can help diagnose possible issues.

    1. Remove all hardware except for one RAM stick from the motherboard and this includes Sata and fan connections to peripherals such as your SSD, etc,

    2. Now see if the system boots with only the one RAM stick. If it boots then shut down add the second stick of RAM and then reboot. If it boots then repeat by adding a piece at a time.

    3. If is doesn't boot then it is either your mobo or your power supply. Also, check to see if your heat sink is seated correctly.

    BTW, nice little system there. :)

    Yeah my first thought was also something shorting the motherboard.

    UPDATE

    I brought the PC in a shop and they confirmed the motherboard had died.

    So I had it replaced with the same model.

    Well the same thing happened. It went fine for a few hours, and then I had to restart and the screen went dark but the computer was still running like last time. I shut down the power for a few seconds and it just didn't start anymore after that.

    I don't understand why it would just die like that a second time.

    Is that motherboard compatible with everything on the list I posted in the first post? ( http://ca.pcpartpicker.com/p/JFVvD3 )
    Should I just look for a different model?
    Or am I just VERY unlucky and got two defective mobos in a row?

    Yes, it has been known to happen. However, I would be concerned about the stability of your power supply. Did they check it to see if it is working properly? The reviews on it are mixed. If a power supply is bad then it will affect everything else in your system and can damage other hardware. Think of it as the backbone of a system.

    As for your parts they go together.

    If they discover it is the psu then choose a good one. For comparison:

    Corsair: http://www.newegg.ca/Product/Produc...tionCA&cm_mmc=AFC-C8JunctionCA-_-na-_-na-_-na

    Rosewill: http://www.newegg.ca/Product/Produc...tionCA&cm_mmc=AFC-C8JunctionCA-_-na-_-na-_-na

    * I really like Corsair's power supplies but I just did a build for the first time using Rosewill's CAPSTONE modular at 550 watt and found it easy to work with cable management.

    * Look int these other manufactures as well: Antec, Seasonic, and Thermaltake.
