hmm, Even if the card have problem, restart should be controlled by motherboard.
They might think I'm a coo for asking them the question.
I am going to try it with my EP35-DS4 to see if the restart problem occurs...
If not, I think it is safe to say that something is wrong with my GA-X58A-UD3R Rev2.0?
If you have any more solution, please let me know.
Thanks a bunch!
