Heya guys,

I just recently upgraded (if you can call it that) from, the

Gigabyte GA-990FXA-D3 Motherboard

to the

Gigabyte GA-990FXA-UD3 Motherboard

Simply because I was experiencing some issues with my older board. I had to got the board today and fully cleaned out and removed all the bits and pieces from my PC, I then setup the MB like normal and plugged everything else in the same as I have done before, countless times. Everything went smooth with the install. The I took it back to my room, plugged all my cables in and did my first boot up with the new MB.

As soon as it turned on, straight from the top of the MB came what I thought at the time was dust but it was smoke, I immediately smelt it and switched my PC off. I thought it was the Processor as I wasn't sure if I put the right amount of Thermal Paste on and was sitting bricks... On closer inspection, a small area near the edge of the MB above the CPU had fried and all along the top of the board just above the ram had friend...

What could have caused this? I put my old MB back in and did all the same steps again, turned it on and everything worked like normal.... No other fried parts or damages on the bootup... I am scratching my head and honestly a little pissed off about the whole thing.
 
Solution
Before you moved the system did you actually power it on before moving it to the bedroom. I mean when the board was put in the case.

If the answer is no, then what likely happened is when taking the old board out.
The standoff positions for the old board differed from the new board.

The spacing and mounting holes differ, in some cases from board to board.
So you have to add or remove brass standoff`s on the board mounting plate of the case.

In other words the holes where you screw the motherboard to the plate of the computer case.
And it is most likely that from the old board and standoff there was an extra one.

That touched a point on the back of the new board causing a short.
Always check when taking an old board out and fitting...

now that is it, the case have an electrostatic charge that what make the motherboard as you said "fried" sorry mate that is the only opinion, in the future be careful and try to connect the case with the ground like tie a wire with a case and put the other head into maybe a plant tub

Always check when taking an old board out and fitting a new one all the mounting holes and standoffs are in the correct place for the new board and no extra ones exist.
Where it will cause the board to short.
By you own self admission you put the old board back in and it worked fine.

So that means a brass standoff was touching the back of the new board because where it was was no hole to mount a screw through and caused the short.

If you look at where it burned on the board and look from the old to the new you will most likely see there was different mounting points. Even with a slight model change the holes can differ.

The only other cause is an improperly fitted memory module.
