CPU running 100% ????

Hi
Can I ask again for your help.
My problem is this when I start up my computer my system runs smooth and fast as expected on a clean install of win xp pro,After a couple of hours any online operations I do all seem to take longer to the extent that I get an icon showing my CPU running at 100 % ,I’ve looked at the obvious the cooling fan but the unit is running cool .
It looks like there is some thing running down my resources in the back ground is there any way I can check to see what resources are running I have done control/alt/del/ but when I look at whats running I have no idea if they should be there or not,could there be some programmes running like Temporary Stay Resident
I have also done a virus and Trojan check I have zone alarm pro firewall , AVG 7 anti Virus and Browser Hijacker running resident

Can anyone help me with this

Maybe try Sysinternals.com Process Explorer

Else check your machine for Ad-,Spy-,Mal-ware.

 

snakefoot
many thanks for that programme

when I checked again last night my computer was running normal later after some hours of surfing I done a check and there was an file called xpnsdis.exe running at 99% slowing my machine down to a crawl.
How do I find out what this is

then post your results in the spyware forum
then someone may request a HJT log
but wait untill asked
that may help


I can't find xpnsdis.exe in google
but I am not done looking elsewhere

I will let you know

 

You can try these steps to reveral the origin of theapplication
1. Try to search your computer for this xpnsdis.exe, maybe the directory-name containing the file will explain its origin.
2. Else when you have found the file, then right-click it and select Properties, then the version-info might explain its origin.

When having just started your computer is the application running ? (Though it might not steal all you CPU time at once)

P.S. Cannot find anything on google either (Maybe double-check that the name you have given us is correct)
