Try running Intel Turbo Boost Monitor. You should be able to see whether the speed is constant or not.
I already install Intel Turbo Boost Monitor. The blue bar only appear in 1-2 minutes after i launch the applications i mentioned above.
After that, the blue bar disappeared.
Try running say Microsoft Security Essential and let it scan your hdd. Look at the TurboBoost monitor bar. It should go up and down. It will not stop at the highest speed but it will momentarily depending on the process runned. Most of the time the bar is at the bottom.
Yes, you're right.
The bar will go up and down when i do the scanning.
My laptop does'nt have any problem with browsing, open video, hear music, and scanning.
But, that still not solve my problem.
The problem still occured when i opened those applications.
Let say i do video rendering or open game, the bar will go up for 1-2 minutes and no problem happened when the bar is still go up.
After that, the bar go down and never go up again, and finally the cpu meter show 100% usage and my laptop become very lag.
eventhough i already cancel the rendering and close all application, the cpu meter still show 100% usage.
After that, i open Task manager, i check the Process tab, and found nothing suspicious application running on my system.
I found something strange, the System Idle Process still have 70-80% of my CPU, but why my laptop still lag and the CPU usage still show 100% usage.
I decided to open Intel Processor Identification Utility and find that my CPU speed and bus speed become very low.
It really strange, because my laptop was very multitasking before this problem happened.
The indicated fluctuation of the TurboBoost monitor bar tells us that turbo boost is functioning properly. Since the problem occurs after two weeks ago, it could mean that something must have been change. Is it possible for you to restore your computer to the two weeks before the occurrence of the said problem?
i already tried to restore my laptop before the problem happened.
But, the cpu problem still occured.
i already tried to format my windows, but the problem still happened.
Since this is a Dell system perhaps Dell support can best give you the help you need to this problem. Check their site for bios and driver updates.
Not help at all.
They dont detect any problems.
The only software that detect problem in my laptop is Intel Processor Identification utility.
