I am using Ubuntu 12.04 64 bit on a laptop with following properties:-
- 6GB Ram
- 500 GB HDD
- 1 GB AMD Raedon 6400 series graphic card
- intel i3 2nd generation processor
- Kernel :- 3.2.0-29-generic
Recently, I have seen that the CPU usage is touching 100% on almost 3 out of 4 cores. And this happens if just browse the web or just install a software from ubuntu software center.
And under the high cpu usage laptop starts behaving like an old gen pc.
I ran htop and the following are the results:-
How can I overcome the situation.
