    Help ! System Interrupts are running are crippling CPU


    All installed OK but unusable due to System Interrupts hogging the CPU. I don't know what these are but I'm unable to stop the process in task manager, the end process box is greyed out for this.

    Did you install any third party drivers? If so, i'd uninstall them

    Hi Mystere, your spot on... I didn't, but MS did. The culprit is the Atheros WiFi driver. I've found a Vista one that works and that has brought the CPU and interrupts right down.
