Help me find out what killed this motherboard (pictures included)

So my Dad has a PC-Chips 810LMR with a 1ghz AMD processor. Yesterday he turns it on and it works for about 2 minutes and then dies on him. It won't come back on so we assume that the 300 watt power supply is bad. I pick up an AMD approved 400 watt power supply for him, install it, turn the computer on, and 30 seconds into the boot, snap, crackle, pop, the motherboard is sparking and smoking and the end result is dead motherboard. Here are the pictures:

Crackle

Pop

Sizzle

So basically, did I kill the motherboard, did the old powersupply take out the motherboard as it died? Did I pump too much wattage into the motherbard? I wouldn't think that a 400 watt power supply would kill it. Enlighten me.

UPDATE: I put the 300 watt power supply in an old computer I have laying around, and it works. So does that mean the motherboard quit and it had nothing to do with the power supply?
 
It means that something is wrong with the board. As in it wasn't manufactured correctly. See if you can't get a replacement board as this clearly is not your fault.
 
I'm pretty sure you're a victim of the enfamous PC chips/ECS quality. I've heard this kinda thing happen to quite a few of their boards. If there is a warranty on it, that is your only hope.
 
Unfortunately at the time I didn't have the foresight to look up reviews on motherboards, so I didn't know it was a crappy board until after he had bought it. It is 1 year and 1 month old, so I doubt he has much warranty if at all. Thanks🙂
 
Almost all PC Chips boards are like that, cheap, and rarely well built. I avoid them at all costs.
 
It's probably just a crappy board but did have the raisers under the board when you put it in? I hope it wasn't grounded to the case. That'll burn it up real quick
 
man I have no idea how that happened.

Those parts are CPU voltage regulator. It drops your 5V and/or 3.3V into 1.x volt required by the CPU.

Is there any short between any part of the board and the chasis? That could do it.
 
I don't know what happened, the computer has been sitting in the same spot running almost nonstop for 13 months and then burns up. It is very wierd. I got another board, put it in, and everything works fine, so we will see what happens.
