CPU Usage @ 100%, windows not shutting down

Ok techies

For the last week or so my PC hasn't been able to shut down. it freezes oin the blue "Windows is shutting down" page. I have to hold the power button to shut down.

As pera previous post, a user profile was seen as crrupt but I got rid of that.

Now I notice that CPU usage is at 100% constantly. In the task manager it seems a process called "SYSTEM" (in capitals) is using about 90% of it. The PC is ridiculously slow now

I ran Norton AV and Spybot and both came up clean. I defragged, I've still plenty of memory available. Any ideas?

Not sure of the the specs tbh but I'm running Windows XP

Looks like the operating system is corrupt or running a process that is using all the processor

Open your task manager and click on process and put what is listed here

Other solution would be programs, accesories, command prompt, type cmd then press ENTER and then type chkdsk /r and ENTER. When it says volume locked type y and press ENTER. Restart PC and let it run the check disk

I've attached a screenshot of the task manager. I cut and paste two screenshots into one image. The highlight line is the same in each shot, showing all processes

I can't restart PC as it won't shutdown probably. Would it matter if I just powerd off, and then turned it on?

That is a process related to Symantec software (maybe Norton Internet Security?)

Uninstall and reinstall the Norton software - or use an alternative product, as Norton is a heap of crap.

Uninstalled Norton. Still the same...

Currently downloading AVG. Will scan the PC with that and see if it finds anything.

Looking at system using 99% it looks to me that there could be bad clusters on the hard drive. I would run the chkdsk /r and let it repair the files. it needs to be switched of though for it to start

SYSTEM isn't the process, it's the user account running the process. In the screenshot you posted, it's using 0% of the CPU, but your CPU is running at 100%
Removing Norton is always a good idea, it's a resource hog, and there are far better options available

Good move.

Dodge, when you open task manager, go to view -> Select Columns -> put a check in 'Peak Memory Usage' or something like that. and arrange by that (double click on the column heading to arrange all processes in order of usage) See what is hogging the most there.

Also go to Start -> Run -> Type in 'dxdiag' to see your specs (click yes to the message if its your first time opening it)

Sorry, I was looking at the highlighted line with "SYSTEM" as the user, mea culpa

Yeah, I just highlighted that to show the middle task, as I had to scroll to see all.

Jeeze, that is definitely the one thing i would leave running. I have it running on a number of PCs and laptops and its perfect. The problem that is being experienced is not related to that.

To remove norton I generally use something like this

http://www.softpedia.com/get/Tweak/U...val-Tool.shtml

it gets rid of all the bits windows leaves behind

Just to let people know I only got this sorted over the weekend. It turned out to be a problem with the keyboard.

Can't stand AVG and all the prompts and popups. Avast is what I install on people's computers, set update to automatic and hide the icons and they wouldn't even know it's there.

What kind of keyboard was it? PS2 or USB? Was it wireless or something?

it wasn't wireless or USB.

The one I'm using now is connected via USB
