    I think my blown up PSU has blown my mobo also.... :(

    AGGHHHH, i'm so annoyed!!

    As some of you might know, my psu blew up the other day. I got another one, installed it but the pc doesn't work.

    The psu fan spins a little. On starting the pc, the following occurs:
    - CPU heatsink/fan spins very briefly and then stops....a matter of 0.5 secs.
    - GFX card fan spins for 0.5 secs and lights up for 0.5 secs too

    Then everything stops except for the little fan in the new PSU...slowly spinning.#


    My mofo is fried isn't it?? AGGHH!!!

    My poor ol' Neo Platinum!!

    What was the PSU that blew up ?

    Have you changed anything in the case - it could be a short on the case ? (then again the PSU fan probably wouldnt be spinning)

    What PSU are you using in there now...it's not an Antec Neo HE by any chance is it?
    Either way, it could be...the new PSU isn't supplying enough Voltage on a particular rail, or there's a short on the Mobo somewhere, perhaps touching your case somewhere.

    I had a box like that, and when I changed the PSU the wires to the speaker melted. Turned out the speaker connections had gone short circuit to its frame, which was crowbarring the 5V rail.

    There is another (no less annoying) possibility: Your CPU or mobo went bang, and took the PSU with it. I would have thought that was more likely than the other way around as PSUs seem to be designed to protect what they are plugged into.

    PSU's, well a lot of them, have a fuse in that blows and will reset once the power cord is pulled out and they have 'somewhat' discharged. ie after about 15-30 mins. Best to unplug from mobo and other devices at the same time. If a mobo/cpu fixes itself, thats just miraculous!

    this can also be a dead motherboard, i had this on a dfi board and they said it was fairly common, and it was a dead "crystal". if its any help, it was roughly a 1 cm x 1 mm silver diode type thing that lays flat and is located close to the battery.

    Yep, sounds like a dead mobo - only way to make sure is to test the cpu in another motherboard - I've seen several socket A motherboards with this behaviour - turned out to be the motherboard in each case.
    Good luck with it.

    OMG!! IT'S ALIVE!! ALIVE!! A-L-I-V-E!!!!

    I can barely believe it.....my mobo came back to life and i'm using it right now to type this.

    I went all the way down to the computer fare at UCL today (my old uni nonetheless), to buy a new mobo....but they were all expensive and rubbish, so thought, screw it, get one from the online retailers after bank holiday.

    went home, got angry that the thing was dead and decided to rip the mobo out of the case. in doing so, i decided to test it once more....and it worked.
    I could barely believe it....something must have given it another chance of life.....a miracle!! or me creating a short circuit somewhere.....but i didn't touch it before...so how??

    Anyway...all is well now. I'm up and running on my new internet connection, and well pleased....not that i got anything extra....just glad i'm back to norm.

    Beautiful Neo Platinum....you were damn expensive when i bought you...but now i know why......you reincarnate....niiice!

    Thanks all for your comments....fingers crossed my Enermax is not going to explode on my, unlike my ex-psu FSP.
