Both the sidebar gadget and the green icon for Task Manager in the sys-tray say my CPU is supposedly running at 100%, however when you look at the processes tab in Task Manager there is barely more than 10% being used. There's also no slow down as you would expect when running at 100%, from either opening new app's or just using them. It's only started in the last couple of hours, even after a restart. Any idea what might be causing this? TIA
