Hi everyone
lately I have had some troubles with my laptop, specifically the cpu speed. I don't know why when the computer is working the cpu throttle gets to really low speeds (once the speed was 350 Mhz

) but when I don't have any program running it gets to the normal speed (2.92 Ghz). Normally what happens is that I start to do something (let's say, youtube) I can watch a video normally for 5 minutes, after that it gets really slow because the cpu speed drops, I stop to do what I was doing for 2 or 3 minutes and the speed returns to normal, and the cycle repeats. at first I thought that it was the SpeedStep, however I don't think that it is, because the behavior is exactly the oposite from what it does, and I have tried to disable it in the power management switching the laptop to Home/Office. Can it be because of the temperature? normally the processor works in the range of 65-70 °C, or what can it be?
here are the specifications from my laptop: Sony VAIO model PCG-K33F, Celeron D processor @ 2.93 Ghz, 512 of ram memory (64 Shared with the GPU) Ati Radeon IGP 345M.
If you need more info ask for it please
