Exclamation ubuntu 12.04 freezes with nvidia driver

i have a big problem with nvidia geforce 8400m gs graphic.
when i have used opensource (nouveau) driver in ubuntu 12.04, there was not any problem but i could not used unity 3d.

i decided to install nvidia propriety driver (version current) to enable unity 3d in my laptop and also gain better performance. after installing that (using ubuntu additional driver) i faced with some weird problems:

1: when i used glxgears with nouveau the results were about 380-420 but now, when i use this command, the results are about 50-60 (i know glxgears is not a benchmark but i thought it might be useful)

2: when i want to start firefox, whole desktop freezes for about 10 seconds (i do not have this problem with google chrome).

3: when i use glmark2, it freezes and ubuntu loged out automatically.

4: in unity 3d, some times the graphic became corrupted for some seconds and after that become normal automatically or by clicking a window.

please guide me.
My System: Hp pavilion dv2690ee notebook, Intel core2due 2.4 GH CPU, 3MB Cache, 250 GB HDD, 2 GB Ram, nvidia Gforce 8400M Gs Graphic
