Windows 7 Downgrade perfomance

I Have a machine With those specs:
AMD Phenon II 955 3,2 Ghzrs Black Edition
Gigabyte GA-MA790XT-UD4P
Kingston DDR3 1.333Mhzs
Powercolor HD4770 512MB GDDR5
Samsung 500GB 32MB Cache
EuroTech 450W

Windows 7 seem to be "unrising" the clock of all component in some sort of Power management, i don't know:



I haven't used any other SO on this computer to try if the problem is with the System or not, but anyone know what the problem might be?
Thanks

1. Are you using 32-bit or 64-bit
2. I will then get latest chipset driver for you....

EDIT: it is normal for a Phenom II to idle at 800 Mhz... It will kick in max core speed once you start a heavy CPU application and go down when the CPU isn't loaded much... STILL I RECOMMEND TO GET LATEST CHIPSET driver... So could you tell me 32-bit or 64-bit... OS

PS: Your hard disk, did you check its model, if its 7200.11.****** and has firmware SD15... PM ME ASAP if you don't wantyou hard disk to fail... Google '7200.11 brick' if you don't believe me... I a Seagate 7200.11 500 GB 32 MB cache with SD15, and it failed.... now RMA...

I don't want your hard disk to fail like mine too..
