    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.

    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.

Did anybody check Advanced Boot options in Msconfig. Seemed to me that my computer is booting too slow, checked those options and lo and behold it's been set to one core only. !!!! After fixing that it boots and run much faster.
