A used mainboard costs about 60 Euros at ebay. Hmm. Is it all done by changing it ?

If all my actions crashing the board, i need a exit strategy

I looked again. no more 8-pinners. the only place i have not looked is the chips under the metal shield on the board. but they seem all to be bigger.

Yes, replacement works as well.
