[965]

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

You don't mention what sort of hardware you have. If your system is low on RAM (especially if it only has 2GB or less) or hard drive space (less than 10% or 2× your RAM), it is struggling to simply set up the desktop.

It could also just be doing regular maintenance such as checking for updates, indexing your files for search, or running antivirus.

If Task Manager isn't giving you enough clues, try using Resource Monitor (Start > resmon.exe or go to Performance tab in Task Manager and press button) to see if a process is taking up CPU cycles or keeping the hard drive busy.

If you do suspect a virus, try running scans in Safe Mode.
