    Hit bump, mobo dead?

    I hit a slight bump today and my carputer just shut off. The Opus psu seems to be working and powering fine, but the motherboard won't boot. CPU fan doesn't turn on but my usb hub lights on. I get nothing on the screen, no CMOS, no boot screen.

    Does it seem like i fried my mobo or my cpu? I double checked the power connections going to my motherboard from my psu.
    THis sucks!! help please.

    Are you getting any POST error codes? If so, that would point directly to the problem (I think "missing battery" is among them.)

    Also, make sure you check all of the connections - power, devices, etc.. Then check them again.

    Start disconnecting peripherals and removing boards one at a time, until it boots up. Or, for an even quicker test, pull the memory, power it up, and see if you get any error tones. If you can't even get the poor bastard to tell you there's no RAM installed, then the board is toast.

    is it possible that your mothoerboard was mounted on top of a metal area and didnt have any insulation under it? it may have just bounced hard enough to make contact and short something.

    If you can't find anything wrong, I'd try the old 'take it apart and put it back together' trick.

    Often if there's something small and stupid causing your problem you won't notice it but when you disect everything and put it back together the problem get's corrected in the process. You may never know what was wrong, but it's worth a shot.

    whats the proper way of mounting a motherboard? because what i did was i got an old case from an old computer and used that to mount my motherboard. The case is metal. What type of insulin and im supposed to use? I think i shorted out the board. There is nothing connected to my motherboard. I took off the PCI wireless card, hard drive, and memory and i still don't get anything. no beep, nothing on screen, no cpu fan running.

    All these signs point to a fried motherboard, huh?

    Can anyone help me with the correct way to mount a motherboard onto a metal board?
    thanks for the help guys.

    You want to make sure that the screw head on the top of the board isn't touching anything other then the metal immediately around the mounting hole itself. Also make sure that the posts that the motherboard mounts to aren't too large and touching anything other then the mounting hole. Use insulated washers (plastic, paper) if unsure and remove any of the mounting posts that do not line up with a hole on the motherboard. You can also remove the motherboard completely from the case and try powering it up that way to see if it's still good. You didn't say what type of system it is but if you can remove the CPU and heatsink I'd also check and reseat them as well.

    Thanks, its a EPIA M10000 board.
    I'll defenitely try to take the board off the metal board to see if it still is live.
    I noticed that the power to my USB hub is still there and also the power light on my PCI wireless card comes on. I really hope i didn't fry this thing.
