Age of Conan freeze zones

Hy, i have a lot of issues with age of conan after i switched to w7 from xp, it's got a lot of freeze zones and the fps drops dramatically very often. Things get worse cuz i have other games too that most of them behave quite good with no fps drops and only this one and team fortress 2 are very problematic.
Some of my games are:
company of heroes
need for speed shift
unreal tournament 3
test drive unlimited
street fighter 4
trackmania nations forever

My cpecifications are:
intel core 2 quad 2.4 ghz
nvidia 9600 gso 768 mb
2 gb ram ddr2

I tried running the game in dx9 and dx10 and there was no change; when i run it i have all the settings from dx9 to max but i don't think that causes the problem cuz i ran aoc at max setting in xp and it didn't have any issue at all.

Do you know any solution to this?

Your problem is impossible to diagnose without more information... Fill in your system specs completely so were not just guessing...Thank you and Welcome to the forums...
