    Hi All,
    very often happens that Win 8.1 starts to consume CPU with the System process.
    The only way to stop this usage is rebooting.
    With ProcExp I've tried to check which thread creates this issue and I've found several threads named "ntoskrnl.exe!ExTryQueueWorkItem+0x1c0" which alternatively make the CPU at high usage.
    Attached some screenshots.

    Moreover, quite often the keyboard starts to write with a delay and some chars are even lost. Mouse is always fluent.

    I'm wondering if it's some hardware component which is not working well (i.e. RAM? Processor? Bus...).

    Any help?

    When was the last time you scanned your system with Malwarebytes, Kaspersky's TDSS killer and an Offline Antivirus product?
