Did you look in the "Windows Task Manager", you may need to show processes from all users, to identify the process that pegging the CPU?

Before the CPU creeps up, right click your Taskbar and select Open Task Manager. In Task Manager, set it to "Always on top" from the Menu bar. Then Select the Processes tab and set the CPU column with the high users to the top. When things start to go pear shaped you should be able to see if you can spot what it is.

Windows 7

Usually when I see issues like this it's the Antivirus, anti-malware, or a combination of the 2 "fighting" each other. One thing you can try is running msconfig, click teh "Startup" tab, and uncheck everyting there. Reboot and see if its better. If it is, re-enable one at a time. If not, click the "Services" tab, check the "Hide all Microsoft Services" box, tehn uncheck all the remaining services, and reboot. Then you can one by one add back until the problem re-occurs.
