    Very high disk usage [Windows 8 Pro 64-bit]


    Hello,

    Over the past couple of weeks I have been getting high disk usage on my computer, causing it to run extremely slowly.
    Is there any way to fix this issue?
    Just after I took the attached screenshot, my System went down to around 6MB/s and the "Service Host: Local System (Network Restricted)" jumped to around 16MB/s
    Looking in resource monitor the main things causing the high read speed are: 'rundll32.exe' and 'ccsvchst.exe' and one just called 'System'
    If you require any more information just ask because this issue is getting very annoying while playing games ect...

    Thanks a bunch
    Jack

    I believe the ccsvchst.exe is a Norton executable, and, as Norton is know to be heavy on system resources, that may be the issue. Now, as to how, why, and what Norton is doing, I have no idea but you might want to try turning Norton off and see if that fixes your resource hogging. Just be careful what you are doing without the AV protection during this test phase. Good luck.

    I'm not sure, Windows will not let me uninstall anything.
    But tomorrow I'm downgrading/upgrading to Windows 7 since I never had any problems with it.

    Thanks anyway
