Hi guys,

I have a troubling issus about my CPU usage. My system is Windows 8 and it running very well, but I can't remember how my hard drive have some DAT format files, maybe I copy somethings cause this but I am not sure. Anyway I want to delete those files, but once I click them my CPU useage would increase to 100%, all I have to do was reboot my computer and the CPU would back to normal. So I can't delete those files in order to avoid the CPU issue.

Who can help me? Wait for your reply. Thanks!!!!!!!
