PSU (Power surge) - Blown out capacitor in motherboard!

I'd like to start off by saying I have a Custom gaming PC. Which I had bought around a year and a half ago however without any flaws until now. :confused

Specs:

Processor AMD FX(tm)-8350 Eight Core Processor
8 CPU'S (~4.GHz)
16GB Ram
NIVIDIA GeForce GTX 660

About a fortnight ago, I had left my computer on for about 4 day's prior to the surge - I don't think that would have made a difference. But I'm going to give all the small details on what had happened.

I was using the computer, when suddenly it decided to turn itself off. I tried turning it back on to no avail. - The power was still connected and I switched off the backswitch of the computer, I saw a spark/mini fire for a few seconds and smelt burnt plastic. I disconnected everything as fast as possible.
One thing I don't understand is if I turned off the switch at the back of the computer what would cause it to surge? It was fine beforehand, when I tried turning it on - But obviously it wouldn't turn on. :zzz

I have bought a new PSU thinking that was the initial problem, due to the fact the computer would not turn.

I didn't use a power surge protector. Rookie Mistake, I'm going to link some images. A capacitor on my motherboard has blown out I believe. :confused

I need some advice, anything would help. Should I get a new motherboard?
Should I try fitting the new PSU and see where it goes from there? Would the computer work without one of the capacitors from the motherboard working?

In a nutshell... Yes, No, No.

The second image looks very discouraging.
There are some brilliant electronics technicians but, they are as scarce as hen's teeth. Unfortunately, repairing has become replacing. Contact your local university, maybe, just maybe, one of the electronics lecturers can advise you.

 

I second Eldon's opinion, new MB. Take a VERY close look at your other components as you place them in the new motherboard, your RAM and CPU are also suspect at this point.
