Hope some of you boffins can help me out here
I use an old system with XP and SP3.
I am a TOTAL dummy on PC
Past few month the system has been slowing down for no reason at all. app svchost shows 100% usage and then it goes away and the system unfeeezes. I do full system scan and nothing detected.
Everytime it slows down and via the task manage I see these apps "svchost" hogging up the CPU.
Past few days I've had issue with "Plug-Ins" not responding.then I thought there were issues with shockwave player...... Yes, every now and then I delete history, Cookies.... EVERYTHING but the problem never went away.
Last night the system just freezes with the high CPU usage NEVER goes down.
I took the PC offline and even offline the CPU usage shows 100%.
The system can be used while it shows high CPU usage. its just at a snails pace. like opening a microsoft word document takes few minutes to open.
How to see these svchost that are using up the ystem are ligit and not some malware, virus etc...
I know I have an old system but till now it has been serving fine.
Please advise.

It is a rather geeky tool but it might help track down what it is that is causing the problem.
so unlike with other programs where if say winword.exe was playing up we could just say your problem is definitely with Word. with svchost we need to know a bit more about it.
what i'd like you to do is install process explorer:
http://technet.microsoft.com/en-gb/sysinternals/bb896653.aspx
it's like an advance version of task manager. but when you hover over an svchost.exe you'll see more information. in particular at the bottom it will say 'services'
next time this happens we need to identify what service is causing the problem.
Now there is no next time. the CPU shows full and it DOESN'T go down
I'm using my netbook here......
Neither IE or Firefox necessarily could be causing any issues. What you need to do is track down exactly what it is that is causing the problem Process Explorer will help identify that. Once identified we can then assist in suggesting solutions.
At the moment I can't instal on that PC due to the bleeping high CPU.
Shall I use the system restore to put it a week behind and see if the system unfreezes and then take it from there ????
An option is to download the install file on another computer. Copy it onto a USB stick. Then boot the affected computer up in Safe Mode (press F8 several times as it boots up before the Windows logo appears and select Safe Mode from the text menu that appears)
Safe Mode doesn't load everything that normal mode loads so might let you copy the Process Explorer installer off the USB stick and install it. You can then reboot the computer normally and run Process Explorer to try and track down whatever is responsible for eating up all your CPU time.
I've restarted the computer half a dozen times and it stil doing it so i'll have to take your advise and start in safe mode and take it from there.
Just downloaded procs explorer.
What do I need to lookout for or how shall I cut and paste the report ?
There are about 30-40 items listed under services for that svchost.
edit: after about half an hour of having process explorer open on the desktop it stopped briefly taking any cpu usage but is back to 100% now.
It should point to the files that re being used. Though I'm not sure if you can copy and paste from the lower window very easily (using a Mac at the moment so can't run Process Explorer to check).
But if you can list the files it shows here that would help diagnose the problem.
Following items show up when I click the services tab at svchost app.
AudioSrv
BITS
CryptSvc
Dhcp
dmserver
Eventsystem
ERSvc
FastuserSwitchingCompatibility
helpsvc
Netman
Nila
RasMan
Schedule
seclogon
SENS
SharedAccess
ShellHWDetection
srservice
TapSirv
Themes
TrkWks
W32Time
winmgmt
wuause
When I hold on the high cpu item a yellow pop up comes up and goes away. I can't cut paste from there
Do you mean where it tells things like "Path", "comand line" etc. ???
I put that gen here later this eve. hopefully i'll get some gold nugets from you and get it sorted soon
If you are going to do it this evening I should be on a Windows machine so can run Process Explorer just to double check what you should be looking for (stretching my one remaining functioning brain cell a bit trying to do it all by memory )
I killed one or to svchost and the system started running again.
Will know what happens when I restart it this eve.
Though depending on what exactly it is you've killed Windows might simply restart the service if/when it requires it later on.
Disabling Automatic Updates in Control Panel will solve the CPU problem after a restart, but if you attempt to do a manual update on the Windows Update site through IE, it will come back temporarily, and it took about 20-30 minutes to show the updates, and it will remain during updating.
So if you decide to get updates, I suggest you allow a lot of spare time.
