    Oldest problem in history but I have some "new" questions so I dared to post...

    What has happened:
    I put it all together and I got it working.
    Just changed the CPU cooler and started to get nasty odor and in one occasion blue sparks (this happened while I was trying to power up using another power unit).
    Got the MB changed and now everything is just dead. Got a little click when power switch is pressed.

    I suspect that the casing is short circuiting (possible)?

    Now, I have put together dozen or so computers over the years and I admit there has been couple of years since I built my last one. But... I read the manuals, remember to but the power on etc. And everything has always been sorted out by testing and changing parts.

    Can I power up the the MB without it being attached to the case? Does it need to be grounded (is that even the correct term?)

    Components:
    SSD drive
    Intel Core i7 2600K
    2x2 Kingston Valueram
    Seasonic X-400 400W power

    Since it started once I wonder if I blew the power supply also?

    Thanks for any replies

    does not have to be connected to the case to test it out as i do that all the time. just power up the motherboard not any of the drives. try another psu to see what happens.

    Ok thanks... maybe I just try without the casing first.
    Unplugging all cables, to try with another psu, is going to a b**ch since it is a tight casing and all cables are individually placed to ensure that nothing gets in the way.

    Would it be sufficent just plugging the main 24pin connector and the extra 4 pin power while other cabels still remained attached to my older gear?

    Well I plugged the wires and hit power:
    There was a miniature sun on the MB!

    Since this is the second motherboard and straight from the store and reaction so violent I doubt I did something wrong. Lack of time has prevented me to study more closely the PSU I used but I'm quite sure I'm not gonna find another 4-pin connector that would fit to that additional power slot. So I'm left to wonder what I did and until I get another MB I don't have a chance to test further.

    Sigh
