My Audio Card was broken and i tried to fix it. I replaced many of the components. After i made the replacements i connected it on to the motherboard but sparks and smokes started.[br]
[br]
I want to ask how to proceed in specific areas on the card.[br]
[br]
First is this area :

It is a connector that connect the Audio Card with the front Interface. It is a 2x10 Pin Shrouded Header DIN 41651 RM 1.27mm.
I do not have the schematic of the Card and i do not have more information. How must i proceed with the fix ?
The problems I see are here :

The bent track was cut, and went to the 2nd top (from left) pin. Should I scratch all these burns? Should I isolate the lower large area of copper that has been revealed, so that it does not come into contact with anything around as well as with the Track that will pass over? (should I put UV Solder Mask Paint after repair?)
In the same area and on the back side, there is this track break:

And here should I clean up (scratch ) before reuniting the track? This little deformed metal ring was completely gone, but I found it and put it back on. The reverse side of the ring, as shown here (the second of the right, above) :

It doesn't go all the way out. Should I put solder?
And finally in this area :

which is very close to the tantalum capacitor that is burned, as you can see, to reunite the track that was cut with the pad of the voltage regulator, I inserted a zero resistance. A while ago I noticed how the area underneath is wet and is probably the flux. Resistor 000 seems to touch with the terminals of the lower regulator but does not touch (it is in the air) Does uncleaned flux cause a problem?
