First of all…regarding the “new” to forums… cant you at least report what are the issues with the card/system board, you came across, in order to users can give some directions?
Is this how you approach a TI department of a repair shop and…“i dont have the options…”
What options are talking here sir? Are we guessing wizards here?

Oh well…another day another surprise.
