PC always at 80-100% cpu?

[punybrick621]

Hello i am not very good at fixing PC so i wanted to ask a question
When i start my pc it is bugged and cant do anything, thats because my cpu is on 100%
It works well when i am at safe mode so i suspect that a program is doing that, but i dont know how to find out what program.
Somethimes eaven Google Chrome uses 50% and skype also 40-50%
I really need help i tried updating every driver it didnt work, scaned my PC for malware and viruses no result i have avast antivirus and avg, and malwer cleaner and advanced system care.
I founded on some forums that i should do something with msconfig but i dont know what.

If u have any solution it would be great and sory for my bad english

1. Uninstall or Disable both Google Chrome and Skype.

2. Check Task Manager and arrange processes according to either CPU usage or Memory usage | check each program that consumes the most computer resources then uninstall when necessary.

3. Uninstall suspicious and unused programs through the Control Panel.

4. Run Disk Cleanup.

5. Check for Windows Updates then download and install when necessary.
