Open the Activity Monitor and View >> View ALL processes. Look for a process or application using unusually larger amount of CPU in the CPU Tab and then perform the same in Memory Tab.

This will help identify a runaway process or Application.

Does the same issue present when booting into Safe Mode - SHIFT key immediately at restart ??
