CPU running at 100% all the time

    Question

  • My laptop fan is constantly running at full speed and is really hot.  The noise is really irritating so i've made a bigger space under the laptop by sitting it on a few lego bricks (best i could find to hand) as the heat that comes out is unreal.  I've checked using CPUZ and the cpu is always at 100% with the temperature typically at 95 degrees C, which can't be good for it.

    I have a Sony Vaio FZ11Z which has a core2 duo t7300 (merom).

    Looking at Windows Task Manager 'explorer.exe' is never less than 48% and often is running at or very near 100%. 

    I know there have been several posts about this, but the ones i've read have quoted other processes and system registries that i don't think apply on my system.

    Any suggestions would be gratefully received.

    Thanks

  • I would say, go for application 'process explorer' (procexp.exe you can find it from windows sysinternals http://technet.microsoft.com/en-us/sysinternals/default.aspx ) and check explorer.exe which takes the most of CPU resources. At the same time, since the reasons causing CPU reaching 100% all the time is various, no hilarious, I would rather reinstall operaing system, which I found actually take the least of the time.

    btw, just came across my mind, have you scan the system against viruses and malwares?
