When I leave my Windows 8 computer idle, the CPU cooler starts going high after 30 minutes or so. When I go back to the machine to investigate which process caused the high CPU utilization, CPU usage is already back and I have no chance to find out what caused the heat.
Anybody knows a tool that tracks history of resource usage, in particular CPU?
You're looking for Process Explorer, a free and much more capable replacement for the default Windows task manager. It graphs utilization of CPU and other resources over time, and by hovering the mouse over a given point on the graph, you can see which process was using the most of a given resource at that time.
C:\Windows\SysWOW64\Perfmon.exe you can fully customize what you would like to watch, and leave it running as well as set the poll time (Every minute, hours etc.).
Process explorer is another free option, but it weigh the system down too much, IMO.
