I wish I can find easily a new motherboard living in the US.. :/exxos wrote: ↑Sun Feb 07, 2021 11:12 pm This has all the signs of noise then... I'm not sure there will be a solution other than change the STE motherboard and start again. Diagnosing such faults can take a incredible amount of time and it pretty much always comes back to the bad grounding on the motherboard itself. Such faults appear quicker than I can diagnose them, it's why I gave up with it all and started with a new motherboard.
At least, the good thing is, I am learning some electronics concepts.
