plesase help my compu is 100 cpu what do I do

-Press CTRL, ALT and DEL at the same time -Click on Task Manager -Go to Processes tab -Click on the "CPU" tab, do it until you see the process using 80-98% cpu This should give you a name of the process. Google it to find out what program it is linked to, and what fixes there are available for it For a short term fix, you can end the process and your CPU will return to normal, but when you reboot it is likely to return Hope this helps
