There are no physical damages, just when I try to drag windows, sometimes it will lag, which never happened before I changed my mobo!
I suspect it was RAM problem, hwoever, when I run the memtest, the result came out good!
Another note is that the CPU temp. is much higher than my first mobo which was GA-7vaxp (26 C) but with my asus a7n8x deluxe (45 C) is this normal?
