Get a small hot-air gun for desoldering, one of the little "gas powered" soldering irons usually has a hot gas adapter - they work best.
A VERY fine iron is ideal for resoldering, if you use solder wire, if you use solder paste (which is applied by a syringe, run a thin line of paste down ALL the pads, at right angles, drop on the package, and then evenly heat with your hot air gun
no, i dont drop screwdriver on it, there is lot instruction about soldering smd part, but nothing tell about solder smd part on motherboard, i need to ask berfore i did it.
The last time I hand-soldered on a mobo was when I upgraded my IBM-PC from 16K to 64K (yep, K - not M, not G, but K) of RAM and it was a royal PITA even with the DIP spacing. Soldering on a multilayer PCB is not for most DIYers; it requires special equipment and a lot of practice. Ie, if ya gotta ask, don't do it.
