High CPU usage

Just wondering if anyone has any suggestions.

I have a HP laptop, CPU usage this week has become constantly high.

I have ran spybot, malewarebytes, MSE, trends online scan. All clear.

I always keep an eye on the start up programs and the only thing starting up with the laptop is the track pad drivers, MSE, the audio driver and bluetooth. I don't have many things installed since I only use the laptop for browsing and emails.

I am about to download avast and run a boot time scan to see if that catches anything suspicious.

Ater running all scans, and running CCleaner I rebboted but CPU is still sat at 80% usage with zero open. I opened firefox to come here and post this and it's hit 100% .

Anything else I should be doing?

thanks.
Sigless

    Task manager > processes should show exactly where the CPU usage is coming from. End the culpable party and see what happens. If that solves the issue then permanently disable it in msconfig > startup and reboot. Of course presuming its not something you actually need.


    If its a running service then stop/disable it in services after checking for dependents.


    Download and run both HijackThis and MalwareBytes Anti-malware but be sure to use 'custom' install - so you avoid the pesky little additions such progs come with nowadays.

    I have checked and none of the processes show high CPU usage.

    Have already ran malewarebytes, it didn't pick anything up.

    Hijack this also doesn't, to my knowledge show anything dodgy.

    click show processes from all users, and cpu column header to sort numerically.

    View, select columns can add more useful information
    Don't you dare criticise what you cannot understand
  • Only a fraction of the 69 processes running there.

    Probably a fair few you can get rid of there also. what is coolsense?

    Thanks, shows system idle using most, which I assume is okay?

    It's HPs CPU fan control system.

    yes, but it doesn't count towards the 97% showing in your last picture, so something else was going on at the time

  • Firefox is using 200MB of memory...

    Avast installer seems to be the biggest hog, Is that the updater?

    What you may find it its detecting an idle PC and using 100% CPU to scan whilst it assumes you dont need to use it?
