    My computer was doing some annoying thing where it'd repeatedly try and power up (sd card reader lights were blinking on and off) and I removed everything from the mobo and it powered up. So I plugged in all the usb connectors and a small black chip on the mobo, near the usb ports sparked. I plugged it out ASAP but there's a tiny black burn on it

    Edit: it still boots, but now there's the niggling in the back of my mind that it could happen again! Should I RMA to be safe?

    You plugged this stuff up WHILE it was running? Could have power surged if you had something in the card reader but NO they will not RMA if board is physically damaged

    Noooo I unplugged the psu cable before plugging everything back in. I have no idea why it happened either, its not like its a chip that had a heatsink that fell off or something

    If you dont push the start button to empty the PSU and mobos capacitors after disconnecting the PSU cable the mobo still has some current and can spark.

    " Yes They Will "

    Example
    How many motherboards have been RMA'ed because of Leaking / swelling Caps.
    or don't you class Leaking / swelling Caps as physically damaged
    or
    Electrical arc/burn damage in Cpu socket ((intel 1156 motherboards had this problem i believe)

    Apply for A RMA what do you have to lose

    My MSI motherboard sparked and something popped. It turned out that my USB controller burnt out and burned up my mouse and keyboard and even portable hd (there was only 1 USB controller on my mobo)

    How can a cpu socket at 1.5v max produce an electrical arc?

    because it controls more than just the Vcore. I took out like 10-12 pins on my 1156 socket due to the memory used and the voltage I was using for it, not the CPU.

    If the Electrical contact is to small or Not making good low Resistance Contact The "Load" it Attempts to carry/conduct will overheat and Burn/arc the contacts (resulting in a Damaged Socket "and" CPU

    Google the CPU power Draw for Your CPU then look at the contact pad/pin size
    Then use Ohm's law to work out the Current consumed By your CPU
    Your be surprised at how much "AMPERAGE" your CPU DRAWS thru the Socket

    Like 20 to 30+ amps now that can arc/burn

    If you didn't cause the damage. I'd RMA it immediately.. I'd call that a motherboard defect and not your fault. Unless you actually caused it.

    I have seen this happen from having internal devices mis-wired. For example I have seen this happen when the internal header for firewire was hooked up to the usb. USB is supplied with 5v, although current is limited, it can still be enough to fry a chip. So it is possible that your card reader or another device is shorting out.

    Okay its just the terminology used here. Electric arcs are produced by high voltage while sparks (like when you short out a capacitor) are caused by high current passing through a small conductor, just like you have said

    But i think we are getting off topic..:)

    Yes just RMA if you can wait for a new mobo. Never know some thing else might go
