CPU running high on one core.
I am seeing high CPU utilization on one core of my core 2 duo proc. one core
stays approximately 60-80% even with minimal os services and no extra apps running. The other core shows no more than 10% at any time, unless loading/executing an application. Task manager shows the utilization, but Processes show system idle at around 95%. I can't seem to track down what is taking the cpu time or if it is just a bug in metering. There are other people in my org that have similar machines, and are not experiencing this.

It might be a hardware that are malfunctioning or a driver that are not good.
I had some CPU problem too but after disabling my PCI TV tuner using device manager the problem went away. Do you have a deskstop or laptop?

CPU running high on one core.
thanks for the information. I was kind of thinking about my ATI drivers being
the issue. I have tried rolling back to the driver that my coworkers are using (default driver included in Vista). This didn't correct the issue though. Does anyone have any ideas on how to identify which driver is causing the issue? I don't see any with errors reporting.
