Fried motherboard in new build

Hey everyone, I have a major issue. A friend and I built a new pc last night and did all the steps and made sure everything was plugged in. when we hit the power button, nothing happened. So I made sure everything was plugged in right and set right, it finally came on, but nothing came up on the screen. The red CPU LED came on so we researched it and tried re-seating the CPU and changing out the RAM, video card and CPU and everything we can think of. Finally we switched power supplies and still nothing on the screen. then we turned in off, checked everything then tried turning it back on and this time nothing happened it all, the pc wouldn't turn on. so we checked everything again.....and again.....and again.....finally it turned on, but when it did, the motherboard started sparking and smoking. I'm just wondering, what in the crap could have cause all this?? I have another ASUS Sabertooth motherboard coming in today, please advise as to what I can do to ensure this doesn't happen with my new board. Thank you.

Double check to make sure all your stand-offs are in te correct place. Having a stand-off that is underneath the motherboard can cause problems like this to happen.

Good luck!

The stand-offs are in the right place, with none extra. We were wondering if it might have to do with the motherboard itself, maybe it is defective...?

discharge any and all static charge you may have by touching any thing metal that is grounded. work off of carpet to prevent static charge buildup and discharge while working. dont have power to the psu untill you are done building.


oh ok. yeah that could be a problem seeing as how we were working over carpet (duh moment). Thanks for the advice. i will definitely move off the carpet.

hope the new board works and your machine kicks sand in the face of your enemy's.


haha thanks. me too

Get some ESD wrist straps if you wanna be double safe. 

I would RMA it because it sounds defective, then the next time you try, make sure you aren't on carpet. It really shouldn't matter, but sometimes it does. Also make sure you check and that the eight pin you are plugging in for the motherboard power isn't the one for graphics cards. They should be keyed so that you can't plug them into the wrong socket, but the plastic these days is fairly soft, so it is entirely possible to force them.

Update: Got the new motherboard install and works like a charm. RMA-d the fried motherboard and should have it replaced in a week or so. Thank you all for you advice, it was extremely helpful. God bless!
