CPU running 100% at times

[noknojon]

I have noticed lately that my CPU runs at 100% especially on several programs (but also randomly) - Facebook is the worst - Always runs 90-100% -

But there have been a few times that it gives readings of 90-100% even when the internet was turned off - I have a screen shot somewhere (will try to find) that shows Internet OFF and still running 95% -

Any other ideas except that it is time to replace - At the moment it is only running about 2-5% ?? -

Thank You -

If you open Task Manager (CTRL+SHIFT+ESC) and tick Show processes from all users then click the CPU column header twice, what process is using the largest amount of CPU when this happens?

iexplore.exe = 70,700K

Have a look at System Explorer

Hello again noknojon, the 70,700K is your Memory usage, not CPU .

Thanks for that link YoKenny1 - The top 5 items are for "very nice ladies" -

System idle process = 89 - 98 is that better -At this time it is flickering between these numbers -

I downloaded the System Explorer but , although it shows a lot of what I already know , it is nothing except another looker at the system -

It will not show how to repair anything or what the actual "fault" (if any) is - ???

Once I posted the figures above there was no answer - Did I get it wrong ?? or is it 'history' for this machine ??

System Idle Process is actually the amount of CPU not currently in use, not an actual process using all that CPU. You'll need to check Task Manager when the issue is actually happening to determine what the problematic process is.

According to the graph it was running at 100% and starting to "rev" a fair bit -

iexplore.exe was reading between 85-95 and System averaged 15

These readings were taken while on Facebook -

Now that it is over (I am still on the net) System Idle Process averages 85 up to 99 -

[exile360]

It actually sounds pretty normal for IE on a page like Facebook, especially if you have Flash Player installed and active as it tends to eat up a lot of CPU. When System Idle Process is at 85% that means that you're only using 15% CPU and when it's at 99% that means you're only using 1% CPU .

So would it be better to use Orca and can you disable Flash Player while she plays on her Cafe or Farm etc -

I never use it anyway - It is just because of the high Revving sounds plus temps go up (according to Speed Fan) -

[exile360]

Yeah, Flash currently seems pretty inefficient, it eats up a lot of CPU so it's pretty natural for it to happen like that. You can use Orca or you can just disable the Flash plugin temporarily in IE when you don't need it on web pages that contain flash ads etc as they will tend to eat up CPU as well when they're displayed.

As a side note, Adobe is working on a version of Flash Player which is currently in beta that will use the GPU (Graphics Processing Unit ie your video card) to accelerate the rendering of Flash based content, meaning your CPU won't have to do most of the work for displaying Flash based content any more.

Thanks for that exile - I think I understand a bit better now -

You're welcome

A simple break down of what the System Idle Process is can be found here and if you want more technical info about it you can check out the Wikipedia article located here.

I would never use any of the applets promoted through Facebook as they are an easy way to infect your system:
