Welcome to Tom's Hardware Forums!
Before you consider repair you should identify what caused that component to burn out in the first place. If not, the fate of the newly repaired component will be the same.
Normally, repair at the 'chip level' is not economical.

To post an image, use the following code:
(Bracket)img(Bracket)URL of image(Bracket)/img(Bracket)
As with Ubrales, it is usually not cost effective to have individual components of a motherboard replaced.
That said, it is very environmentally friendly and a fun at home project if you have some skill with an soldering iron
If you can post a clear picture of the component, along with an overview of the board indicating its approx. location, someone on the forums can probably get you pointed in the right direction.

If you are going to repair it yourself I suggest using solder paste, not solder wire. The solder paste has the flux i n it and is easier to 'paint' (dispense) at specific spots where you need it. Also, solder paste can be dispensed with a syringe.

It is also known as 'soilder cream" because of its creamy composition. It is primarily used in SMT (Surface Mount Technology) where it is dispensed by screen printing on to the circuit board. This way it can be precisely dispensed just where it is needed; on the traces and on the pads.
Type 2, type 3, or type 3 will work well for you. In fact, for repair purposes just about any type of solder paste will work. The finer grades are used for tighter spaced components on the circuit board. If you can, get the water soluble grade because it is easier to clean after the repair.
Use a magnifying glass and a hypodermic syringe for precisely dispensing the solder paste (cream) just where you need it. The component (chip in your case) will stick to the paste and stay in place during the solder operation. Use a hot air gun on high heat and low air flow in order to ment the solder paste and also prevent the component from moving around during the repair. It will be a good idea to lightly hold down the component during the repair. Molten solder is like a skating rink and components may move around.
Good luck!

I would suggest something like a 30v 2a N-Channel first, (ex FDS 6682) because the source Pins are on the negative trim of the motherboard. That would be a replacement, but you would still have to find the source of the short. Buy 2-3 when you do find an equiv. part number. If it doesn't fire up or no lights then you can try P-Channel. (AO4413 or FDS6679)

I have tried to read the specs on the burnt chip, I think it reads
K 261
G546B2
and it is supposed to be linked with the internal hard drive (powers it).
What would you suggest about terminology of this part so it may be easier to search around.
cheers!
