mainboards should not be put through such torture .Lay them to rest with honor after you throw them across the room stomp them into the tile like the crap they are. Run over them with your mobile unit , plug them into a 220 socket ( you no you want to )
A couple of slams with Galiger`s hammer . Finaly after you`ve paid it back for all the stress it has caused you .Bury it in the back yard .
