Laptop using 100 CPU

[Dannykw1]

I found the process causing the problem. System Idle Process is using 90 CPU. http://gyazo.com/9426d8fca21de24f6e703371962d68c1
How do I fix this?

System Idle process is the portion of potential cpu power that is NOT being used.

Not sure what your problem is but that is not it

Oh, not sure if this helps but http://gyazo.com/7d72000831a14cb23d6855c1fdf58215 is there any way you can help me fix this? As soon as I start playing Counter-Strike: Source, CS:S uses 100 CPU.

Without knowing the other specs this is hard to say. Could you list the specs? Also could you take a screenshot of the cpu usage while on idle and during the game on the task manager?
