CPU usage in idle
Hello,
I have question regarding CPU usage when my laptop has not have any application up and running (at least not by my request).
I have changed some of the Start Up in msconfig. Everything that I don't really need on immediate Windows start up I have not selected. That is fine.
But still absolutely randomly I will have my CPU usage going up and down from 1% to sometimes over 40% if not even more. Recently what has happened is that I left task Manager up (only, nothing else) in order to monitor CPU usage. While I was watching CPU usage was as I would say normal. 0%-7% up and down. After let say 45 minutes I got back to check again. I log on and much to my surprise I have noticed that my CPU usage in last, at least 10 minutes was constantly around 40%-50%. Strangely enough few second after I log on CPU usage has dropped down to the previous percentage.
I am talking over here about Acer 5378Z
4GB RAM
T4300 Dual Core
WD320GB 5400
Intel Graph (up to 1.8GB share memory)
Windows 7 x64 Home Premium (with latest updates)
Do you have any idea what it could be?
I also scanned computer against viruses and malware. All clear.
