Something is eating my CPU

Turned my PC on this morning after a long while of not using it, did some updates and what not and just browsing t'internet at the moment.

It's being a bit of a pain in the rear end as the CPU seems to be going mad without anything really going on. The performance bit of task manager shows this:

But my processes are just this:

And there's no delay between taking the screenshots, barely a second or two.

What is eating my CPU? :confused:

I have AVG Free 2013 installed and up to date, btw.

Show all proccess?

You have 66 processes running while showing us about 20.

My bet is the DNS Client Service is chewing up cpu power.

Have you got a massive hosts file or have you let Spybot Search & Destroy immunize your system?

Click the "Show processes from all users" button, and post screenshots.

He set the list of cpu usage from high to low
Software incompatibilitty probably

You've probably got something running as another user. I'd be surprised if it's AVG .

I find the resource monitor can offer some more useful insights as well. How does task manager quantify CPU Usage? Number of threads or some other metric?

Ripshod · 5 Jan 2013 at 18:28

Pure CPU usage as a whole (all cores combined). So if a program shows as using 30%, it is using 30% of the whole CPU. You can add more columns to the processes tab, such as thread count and CPU time etc, but I find the default adequate for the purpose. The resource monitor is handy if you need to go deeper into it.
