Question CPU speed dropping continuously.

[humanturtleduck]

Recently, my laptop CPU speeds have been dropping and going up again in a pattern. It used to be running at a 3.20 MHz but it often drops down to 0.19 MHz and spiking up again. This causes alot of sudden lag spikes in what im doing.

on battery or plug in? what the cpu temp?

All 4 cores are chilling around 38 to 42 C usually while web browsing. I have it plugged in also. And i think what they call the CPU temperature (Temp1)is around 52 also. (It shows a flaming sign next to the temp in speedfan which i dont think is good ._.)

Oop, apparently the problem was solved when my laptop was fully charged. I dont know why, but, if its plugged in at 90 %, the CPU speeds still drop. After it was fully charged, the CPU was very stable.
