Recently while using my laptop (Dell XPZ15z) all of a sudden the CPU usage is spiking to 80-100% then will drop in say 5-7 sec. I am not running any application or process that requires such CPU usage.
I am doing a lot of online gaming, while playing the same thing happens but the additional things happening are that the ping becomes 1500+ all of a sudden from 90-130 and then its showing network connection problem. Then I regain connection again in 5-7 sec. But now i noticed its the same time while my CPU usage is going above 80%.
Another incident that occurred is that while I was watching an YouTube video, all of sudden the video began to hang even though it was buffered earlier. Then the video stopped further playing and I saw that the CPU usage was way beyond 80 nearly 100%.
I increased the virtual page memory to almost 10 GB in all the drives. But it seems to have no effect as the problem continues. I have up to date anti-virus (Avast) and I scanned the whole system but no virus also have been found.
My system configuration is as follows:
- Intel Core i7-2640M 2.80GHz
- 8Gb DDR2(4*2)
- 750Gb HDD
- Nvidia 525M graphics card

capture a xperf trace when you have the issue and upload it: http://pastebin.com/pgE11HRD

@magicandre1981:These are some snapshots of CPU usage while the problem occurred. https://docs.google.com/file/d/0BweeVUiqmiuQWDloY1o5dTBfQWc/edit?usp=sharing https://docs.google.com/file/d/0BweeVUiqmiuQc2gxNEdjSUZ6NUk/edit?usp=drive_web

More important would be the red line which shows kernel times (can be enabled in the options menu). You should also look for the process or service responsible for this because *obviously there is a process running that causes so much load*. – Joey – 2013-10-10T08:31:11.697

Try using the Process Explorer tool from SysInternals (via Microsoft) as this gives much more information about running processes: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

@Joey:Ya obviously i looked in the process tab but i couldn't find any process taking so much memory. – Krishna Chandran – 2013-10-11T09:06:26.677
@Richard:Thankz for the info bro.Let me try it. – Krishna Chandran – 2013-10-11T09:07:09.447
@Joey:I have installed it.If you could specify what should i look for it in particular, it will be more helpful. – Krishna Chandran – 2013-10-11T09:10:57.800
