CPU Frequency Drops > Issue with amdppm.sys
I hope someone can assist me.
I have been having a problem whilst gaming (although this also runs over onto net use when playing flash games ie. pokemon global link), I've noticed that my pc/game would stutter immensely for a while and then would run fine again.
I've found that in resource manager when this happens that my frequency rate drops from 100% to 25% and then after a time goes back to a 100% (stuttering then stops)
At first I thought it was with NT Kernal & System and through that and following a guide on how to locate the problem, I've established that it is the driver amdppm.sys
I'm not a terribly technical person, so thanks to all the tutorial makers out there.
I've then tried replacing the amdppm.sys with a different version of the same file, the stuttering stops, however after a period of time, my laptop would shut itself down completely.... so I replaced the previous file that I had thankfully made a copy of.
As helpful as google, this site and various others have been. I've yet to find a way to rectify the problem... without causing anymore and as I've said, I'm not terribly technical and fear that I might worsen the problem more before ever being able to fix it.
Please if anyone knows of a way to fix this, it would be greatly appreciated.

It is normal for a mobile processor, in say a laptop, to reduce its clock frequency during inactivity. It will do this to save power, reduce heat, prolong battery life etc. There is no need for the processor to be running full tilt if it isn't doing much of anything. when needed it will go back to full speed. If you are running on battery when this happens try plugging in the power pack/charger and see if the problem goes away. Why its down clocking when you are actually using it I don't know? I don't have a laptop of my own at the moment.
