MOSFET blew out

Hi guy,

I got a new PC. I assembled it and when I powered it on for the first time there was a spark and one of the MOSFET of my motherboard blew out. It litrally blew out of the motherboard and fell on the floor. But the PC did start normally. The mosfet was little below the CPU Fan pin. Once the mother board started it gave CPU fan error. I had plugged my NZXT Kraken x61 in it which didnot work so i had to shut down immediately and put the Kraken in the CPU Optional Fan header in which it worked. Now whenever I start my PC it gets stuck at CPU Fan error before windows loads up. So then I put one of my chassis fan in cpu fan to see if it boots but the chassis fan also stopped working and still it did not boot. Then I changed the boot priority to Disk and it did boot to my windows on my HDD after skipping the "Press any key to Boot fromm CD/DVD" screen.

Now the motherboard is working fine except the CPU Fan header and sometimes the NZXT CAM software not reading temperatures correctly and I cannot change the fan speed and led light color till I restart. I will be giving the Motherboard in warranty. But I want to know if there was any of my mistake of I just got a bad product and also the NZXT CAM software problem is a hardware issue or software issue.

 

Thank You

Did you check your standoffs? Sounds like you shorted the m/bd and it's now toast. I have no idea why you're fiddling with it, anything you do to it will screw up the install of a working m/bd.

But I didnot OC it and according to my knowledge I installed it properly in my case Corasir 750D which has standoffs built-in.

The motherboard is new so why would anyone solder it? Just RMA it and get it properly replaced, you only really solder on MOSFET's and Capacitors when the motherboard is no longer under warranty.

Why void warranty when you can get the Motherboard RMA/DOA'd ?

The motherboard is Asus Rampage V Extreme and PSU is Corsair AX1200i. Both are brand new and was used for the first time. I am from India and I have heard from people that the warranty doesnt work when something is burnt or blew out.

Warranty.

If not;

Solder.

I personally would check the CPU cooler isn't shorting. I have heard of faulty fans setting things on fire...
