Re: Intel DG965RY power on every time main AC power connected
That chip is the main I/O controller for most of the board.
Unfortunately if that is shot the board pretty much is too.
They can be replaced if you are VERY VERY good at soldering [or have the fancy expensive tools] but I think you'll find it's easier, faster, and probably less expensive to replace the board.
[Just finding a new chip can be a major project sometimes and they aren't always cheap.]
I don't even try to fix those unless I have a good replacement chip on an otherwise dead board in the scraps box.
.
Looks like it took a voltage spike or had an excessive current problem.
Could have been from bad caps, bad PSU, disconnecting something with power applied, or some voltage regulator chip failed.
.
I'm sure that's the last thing you want to hear after you have all that work into it.
.
Here's the data sheet for that chip.
