I am having an issue where I push the power button on my PC and the power comes on for a half second, then off, then on, then off. After several seconds, it comes on and the fans spin up then regulate; but I never hear any POST acknowledgement and it goes no further.
I have had this same issue before and had replaced the power supply, but the same issue occurred. I then replace the motherboard and fixed the issue. So this is another copy of the same motherboard with the same issue. I am wondering if this is a known issue as this board is no longer available.
Instead of replacing the motherboard again, do you think it may be something simpler? Like a bad CMOS battery? I am not sure what would make the power flicker like that. If the motherboard is sending a signal back to the power supply that all is well and is letting power through, I can only think that the motherboard is bad again with the same problem.
