    Hi all!

    I recently formatted my ASUS N43SN, when suddenly this odd problem occured.

    Whenever I use a program that makes the CPU work really hard (typically Minecraft), one of the cores stays in 100% after I have closed my applications. This core constantly works in 100% until I shutdown, restart, PC goes to sleep mode or hibernation.

    None of the open processes in the Task Manager is using anywhere near this amount of power.

    I've googled around for a solution to this for two days now with no luck. I have reinstalled Windows in a different partition, installed all latest drivers and flashed my BIOS, but for no use...

    Anyone got a solution to this problem? Thanks in advance :)


    EDIT: Heres a screenshot of the task manager

    Run LatencyMon and see if it reports anything unusual, in particular in the per-CPU view.

    Hi,

    You can download the Process Monitor that would show you real-time file system, Registry and process/thread activity. Its uniquely powerful features will make Process Monitor a core utility in your system troubleshooting and malware hunting toolkit.

    For more information about Process Monitor please see:

    He said he closed down all processes. Since everything is tied to CPU0 this looks like an interrupt or DPC problem. Some chipsets distribute interrupts among the available
    processors while other ones always direct to CPU0.

    You wrote "none of the open processes in the Task Manager is using anywhere near this amount of power". That makes me think Process Monitor will not be of help here.

    >How do i "run LatencyMon"?

    Click the icon after you downloaded and installed the software.

    Installing Intel Turbo Boost Monitor appears to have fixed the issue. I guess all that crappy software that comes preinstalled with the PC isn't so crappy afterall!

    Thanks for your help anyways :-)
