    A Gamble between a MOBO & CPU - No POST


    Laptop Boot Issue

    I have a Gateway Nv53 laptop. I am having some issues with it. It does not boot.
    When ever I turn it on The BLUE led is on and I can turn on a few media keys. But the activity light is missing and no display to the screen. I plug off all the peripherals, removed and re add ram and battery. Now sometimes if I turn it on and leave it and restart after a while I will get it to boot and when it does boot it can stay on forever without problems but once its shut down even after 5secs it won't boot up again


    Now after a couple of weeks it starts to power on after many tries and runs but I encounter a random shut down when I try to play a game for too long. I went and got a new set of ram and it still would not boot.

    Now I am wondering if I need a CPU change or mobo.

    Unlikely to be the CPU. Motherboards are available on eBay for about $50.

    OK because when I turn it on and connect a Ethernet cable I see both green and orange lights and also the hdd is vibrating. So I'm really curious

    If you've disconnected everything except hard drive and display, and it won't post it pretty much has to be:

    memory
    hard drive
    psu
    mother board
    cpu

    That's the order I would work with.

    Phill your post #3
    hdd is vibrating
    --------------------
    That is not good. Hard drives should not vibrate. If you put your finger on a hard drive when it's working you should feel that it is working but not vibrating.

    Your symptoms are typical of a cold solder joint on the MOBO. Google "mother board oven repair", this is a last resort but worth trying before replacing the mobo.
