Heya guys,

Below is the steps I took installing my new Motherboard, I want to know if anything I did in this process could have caused enough static electricity to fried my motherboard on start up...

A few things I want to clear up straight away...

1. No Carpet in my house.
2. PC was worked on, on a wooden table, the PC was laying on a towel which was spread across the table.
3. I had no static bands on, I was wearing shorts with bare feet.

Firstly I unplugged everything from my tower and carried my case to the living room (about 10 meters, crossing from tiles to cement to tiles and up 2 stairs) and placed the tower on the table I had mentioned in 2.

I went about taking out each component piece by piece and laid them on the kitchen bench, once all components were removed I dismantled the case and removed the fans for cleaning, each piece was taken out the back of my house and sprayed with an air compressor to remove any dust that had built up. After each piece of the HAF X was cleaned I put them all back together and placed the fans back in the same positions.

After this I installed the motherboard first, I took it straight from the static bag and placed it in the case then screwed it down to the pins which were in the same location as my previous motherboard (as it was 1 model up), after that I required the assistance of my father who helped put the CPU cooler on, he held the back plate to the motherboard as I screwed the CPU fan back on. After that I put each component back in (as I had done in the past).

I then carried my tower back to my wall mount (my case is wall mounted) and plugged everything back in as I normally would. Upon bootup a small puff of smoke shot out the top of my motherboard and went straight up and out the 2 120mm fans. I could immediately smell smoke and shut everything off straight away, the pictures attached show damage I had noticed on the board.

I have recently purchased a new motherboard and will be installing it this week, I have also purchased static wristbands for both myself and my father to prevent anything from occurring gain, is there anything I should be aware of this time I do the install??

its always been my understanding that any damaged caused by ESD, is caused immediately. your mobo essentially blowing up after turn-on seems to indicate a bad psu, something being wired incorrectly, or some other part that had failed or been installed incorrectly.
there are a dozen things to suspect before ESD IMO. i never use bands or really any caution whatsoever (not that i suggest this for anyone) and all my builds have gone on without a hitch.

even had an open bench PC (mobo etc on an open table) get rained on for over an hour while running SETI@home and it still worked for years after
 
static short wont cause a burn like that. a static hit will just kill a part or parts...some things that can smoke a motherboard is pluging a floppy power plug into a fan or audio header. the wrong dimms and or bent pin in ram slot or under the cpu.
the cpu cooler back plate if it metal and not plastic can short out the cpu. putting a cpu in a mb that pulls to much power on the vrms. check to see if your cpu on the mb qal list. check that the mb io shield fingers did not short out the mb. check on the mb for broken off caps. if there been snapped off in shipping then you can have a short when you power on the mb. check to see if your case tray is flat or stamped..some trays can hit bottom of thin mb and short them out.

My PSU seems fine, I mean I got a new one about a month ago and had no issues with it and my old motherboard. What do you suggest I do this time to prevent anything from happening again? Possibly only plug a few components in instead of doing them all at once?
 
if the motherboard was new..call up the vendor see if they rma it for you. if it was used check the mb user guild and see that your cpu that you used is on the motherboard guild. also check your ram too. with the next motherboard just put in the cpu and one stick of ram and a video card with the mb outside of the case and post the mb (bread board it). let it sit there for a few min make sure it working fine. then turn off the power supply and then put the mb into the case. before you power it up again in the case check that there no pinched wires under the mb on in the fans..look for cut wires or wrong wires in the wrong plugs.

I swear everything was okay but I am guessing I had missed something, one thing I do notice is the 2 fans + water cooler block thing for my CPU cooler sits over the CPU Power Inlet on the motherboard (if that makes sense) I will have to check it a lot better this time
