I have a Vista Basic system that now runs at 100% CPU usage but looking at the Task Manager there is no process using anything close. Most of the CPU seems to be used in kernel mode.
The problem does not exist in Safe Mode and a SpyBot S&D and AVG scans show no problems. However boot back into normal mode and very slow running again.
It does not happen as soon as the system starts up but after it's been running a minute or so. Also it seems worse if the machine is not connected to the internet.
Question is there anything I can run to identify what is using all the CPU?

Thanks

Russell
