    Hi,

    I've built a new PC
    Gigabyte GA-X58A-UDR3r
    Intel 950 proc

    When I fire it up it starts to power up but then shuts straight back down within a few seconds.
    The ammount of time varies.
    Sometimesa I get as far as the Gigabyte splash screen but it then shuts down.

    The board has some diagnostic LEDs. The ones to indicate CPU loading (phase LEDs) are on full.

    There's no digit display so I can't get any more info.
    Has anyone had this experience or can offer any advice.

    Cheers
    C

    To me that sounds like a broken PSU. IMO the second most likely cause would be a defective mobo.

    Any beeps?

    Any chance you could fill out your specs?

    Should just double check everything.

    Make sure your cpu is properly placed.
    Make sure your RAM is pushed in tightly and you hear a "click" sound.
    Make sure all your connectors from your psu are in properly like the 8pin to your mobo.
    If everything checks out then you most likely have a dead mobo.

    Hope everything turns out fine.

    Thanks very much, I'll do that now.

    No beeps.

    Spec:
    Gigabyte GA-X58A-UDR3r
    Intel 950 proc
    3 x 2G Corsair 1333 DDR3 XMS3 RAM
    Akasa Nero Fan
    An intel SSD (gen2)
    An ATI 5870 gfx card
    A seasonic 600W PSU.

    I say it's a new build but the case and PSU are from my old machine and were working yesterday. I also have a sound card and HDD but I haven't added them yet.


    Thanks

    I almost cant imagine someone doing that step wrong :)

    This I'd easily exclude,improperly pushed im RAM wouldnt cause such a failure.

    Hmmm...

    Well provided you performed all the requisite checks (all cables snug, everything seated properly, nothing shorted) my only other suggestion would be to run the minimum complement of hardware (mobo, cpu, 1 stick of ram, no HDDs, no gpu) and see if then she'll stay powered on. I'm betting she won't because it's probably a defective mobo (or, less likely, cpu). Sorry.

    I didn't seen it myself but I've heard of someone pushing the CPU clamp down (on one of the old 478 style sockets) when the CPU wasn't properly socketed. They then proceeded to put the heatsink on (which fit rather tightly because the CPU was standing on it's pins) and ultimately attempted to turn on the system. It did not end well.

    I'm not sure if that's just a myth, but it's funny.

    riser = standoff (You had me confused there for a second. Risers usually refer to another piece of computer hardware.)

    risers.

    make sure you put them in

    their in?

    make sure their tight.

    their tight?

    make sure you have one for every hole on the mobo.

    you do?

    make sure you put a piece of electrical tape under any part that may be flexing because of the cooler or other weight bearing parts right under the mobo on the tray or the mobo itself.

    seen it a million times.

    incorrect. i didnt push down 1 stick in my system once during a rebuild. she booted into windows but it would spontaneously reboot BSOD or shut down. it could be 5min or 1 hour

    Cheers.
    Just had the CPU off and it looked fine, reseated it anyway.
    I'll stick the fan on and see if that works.
    Else, I'll have a look under the mobo to see if that is touching the case and stick some tape in, that seems like good advice.
    Ta all.

    try to put the board off the case, it looks kinda short circuit or something then check the processor and ram then the cables

    Well, I took it alll aprt, stuck a bit of insulating tape on the case under the MB (although it didn't look like it was touching.
    ...and it did the same thing ... once.
    Now it is powering up.
    And no more CPU load leds on.

    I'm not going to start celebrating just yet, I'm going to carry on putting stuff on it and seeing what goes down.
    So far so good.

    Cheers you lot :respect:

    You might have not seated the HSF right so the CPU was overheating as soon as you powered on causing it to shut down to protect itself.

    i don't think you have a large enough psu for the graphics card and that processor,
    get a bigger powerpack, although it should power on tbh
    btw i have a less powerfull cpu (i7 920) and i use a 850watt psu

    LOL

    Well, its the mobo, power supply or Proc I think.
    Sometimes it'll work and kepp working evey time I cycle the power.
    Then I'll add sometinng and its tops working, take that some thing away and it still doesn't work.

    I took insurance on the bits from the supplier but I don't know what to send back.

    The power supplu buzzes very faintly (as you'd expect) but the buz is irregular so I'm strating to worry about the PSU, but it worked fine yesterday on my old rig.

    Thanks all.

    I don't think the PSU is the issue, it fails even with out the GFX, it does feel like a short circuit.
    Just had a look at the back of the mobo and the conformal coating is very rough looking.
    Noy uniformally shiney and the hint of a finger print here and there.

    It's going back.

    that PSU should be enough for your system, but that don't mean the PSU is fine. I recently went though basically the samething with another computer I built for someone, replaced the PSU, and the system is working fine now. It may work in your old rig, but I doubt your old rig pulls as much power as your current rig. Unless your old rig isn't that old and is running a newer(GTX series) NVIDIA GPU

    First off, +1 to all the other posters here. Lot's of good advice that I don't have to repeat. :rockout:

    Now, I've seen something like this recently. My friend built a PC from brand new, good quality components and his Corsair PSU refused to work properly with his Gigabyte mobo. It would do stuff like not start up, just suddenly reboot, do a spontaneous controlled shutdown (this one was weird) etc.

    Separate those two components and each one worked fine, so go figure. :wtf: Likely one or both is made out of tolerance somehow, which doesn't show up with other components. It's a sucky situation and keeping them separate is how this was resolved.

    However, if you're hearing an irregular buzz/squirly sound* from your PSU, then I'd suspect that in the first instance and get it replaced under warranty. I've had Seasonics before and they're excellent, quiet PSUs that don't sound like this.

    If you can, try separating your PSU and mobo, to see if they both run stable.

    Oh and please fill out your specs like streetfighter suggested in post 2. :) You probably didn't realise it, but he provided a link that takes you to your system specs profile. This means that a link to you system specs appears under your username, that anyone can click on. Have a look at mine for an example!

    *Having said that, it would tend to vary a bit anyway, with the loading from the rest of the PC, which does change from instant to instant. Someone with a lot of PC experience, like me, would tend to know whether the sound is normal or not. "Squirliness" tends to indicate more of a problem than a (faint) buzz.

    Maybe old trick with soft off? You could have defective/stuck power button (or shorted MB power-on pins, cable), and that causes PC to turn off right after torning on. Try to turn PC on using screwdriver to short the pins.

    I had something similar happen a while back. Ended up being a problem with one of the memory slots in the motherboard. Got a new motherboard and the problem went away. Best of luck getting it to work!

    Well the supplier thought it was the power supply as well, but it isn't because I just went and boght a new one and it does the same thing!
    Sending the board back :shadedshu
    It's a bit gutting as I was hoping to get it all up and running this weekend but, oh well, that's life.

    Thanks to you all, you're good helpful folk
    So helpful that I'm going to give you another one of these :respect:
