I just had a q6600 with a ga-p35-ds3r working ok, but as soon as I put a q9400 in the same machine I got no post, no beep, no video, fans do spin. Gigabyte site says last bious update support q9400 si bios already updated, already cleared cmos, but nothing, same result. can{t be memory or power problems since they do work with my q6600.
