You told, that even when only coming near the keyboard with your finger the mainboard will run ill, right? Then please make the following test: Remove the cable between keyboard and mainboard, so that the connector end is farer away from the mainboard than about 2cm, so that there's no longer any connection between keyboard and mainboard, even not via screws and other assembling material. Start the mainboard now. Come with your finger near the keyboard, do even touch it. Will you now observe any malfuntioning of mainboard?
Afterwards, connect the keyboard cable again to the mainboard and all the other assembling material. Start the mainboard now. Come with your finger near the keyboard, do even touch it. Will you again observe any malfunctioning? Kai |
