Amd phenom II 965 3.4ghz help!

Just run some program that will stress the CPU a little, and the speed will jump.
The clock is so low because there is no need for more. With Cool and Quiet enabled, this is a way the system saves power and stays cool and quiet  

wow,tnx man was rly scared that smthing was wrong with it...by the way what's the normal temp for my cpu when playing games?
atm is sitting 40-50 degrees but when im playing bf3 goes up to 80

80 is too much, that's a problem. Is your heatsink and fan properly installed?

yea,it's mostly sitting on 40-60 when playing wow,but when go with bf its between 70-80,and my fan/heatsink was installed by the company i bought the pc,so i don't think that's the problem...i was thinking about thermal paste change,it's probably time...around 3years now that i have this pc...

Is the inside of the PC clean? If you haven't cleaned it a 3year old PC would be full of dust horribly chocking the cooling and causing over heating.

i recently had it cleared from the dust...as much as i could&reach....so i don't think it's that...
