Abnormally high CPU usage despite Task Manager Breakdown

[Azade12]

So my PC has been slowing down recently and I'm trying to find reasons why.

I look in Task Manager, and the CPU usage is fluctuating between 60-80% despite the breakdown adding up to be anything below 40 or 30. Is it a virus maybe? I've done scans with mbam and it hasn't detected anything so far. My CPU is older, however I'd expect to see the breakdown numbers to be accurate.

it might not be showing processes from all users.

But just quick math in my mind, I don't see a huge difference in CPU overall and all the small numbers...

You should just close thing you can live without... I don't see much sense in having a web browser while playing a game, unless you are streaming music.

First check the Users tab of Task manager, to make sure there's no remote access causing issues. (Small chance but easy to check) You should only see your user account or the accounts that you intentionally have logged in. 

Instead of opening up task manager, check resource monitor's CPU tab. (open from windows menu) See if that gives you a more accurate representation of what's going on.

those numbers somehow never add up, but the % is still largely accurate... 

 

 

What are you doing that your pc is using up so much cpu... is it downloading something from steam..? 

 

 

those numbers seem all much too high... 

 

Also all that manufacturer proprietary crap is dragging down any pc, I'd definitely deinstall or make sure it's a least not running... 

 

Well, personally. but up to you, but since you're apparently asking about abnormal usage that's my answer here. 

 

Or did you really just want to know why it doesn't add up? 

 

Answer: Windows.
