I'm a novice, but checked task manager and watched, With just one firefox internet window open, cpu usage spikes randomly up to 100%. The computer has been running slow. I have XP

Which process is using all the CPU?

Hi,

System Idle Process it what uses most of it, it varies from 77 - 86 %

I checked my free space on my local disk C, I have only 1.3GB free out of 19.1GB, could this be the problem?

Thank you so much for trying to help me.

System Idle Process is just a count of all the CPU that is not being used. So it's a good thing if the System Idle Process is running high. What else is using the CPU?

1.3GB is starting to get a little small, but I wouldn't think it would cause high CPU spikes. Still, it wouldn't hurt to try and free up a little more space.

Firefox.exe 13-34
Teatimer 02 or 03

Explorer.exe 02 or 03

tastmgr.exe 03

The column, when sorted by higher number under CPU keeps changing by the second even though I'm not doing anything on the computer, is that normal? Most other items are at zero on the list in task manager. When I go to the performance tab I see it spiking to 100% every few seconds.

It is normal for the processes to keep changing order when sorted by CPU.

If on the Performance tab it shows CPU spikes I would expect that something would show up under the Processors tab using high CPU.

Honestly, it changes so quickly the 3rd and 4th place items keep switching, I cannot read them well.
1st place is always system idle process
2nd - 4th is usually firefox, taskmgr and explorer and teatimer

Mcshield and hpq??? and alg.exe sometimes move up to 5th or 6th place.

Try using Process Explorer, which is a more in-depth version of the Task Manager.

Ok. thanks, the new program you recommended is running. The only new thing I noticed using CPU is


procexp.exe

services.exe

csrss.exe

these move up to the top 4 places when sorted by CPU usage.

Right click on service.exe and select Properties. Then click the Threads tab. Do you see anything using lots of CPU?

after clicking on threads tab I got an error,

"the version of Dbghelp.dll configured does not support the microsoft symbol server. Please download and install the Microsoft debugging Tools for Windows to get a version that does"

I clicked on the link to install a M. debugging tools for windows, but it brought me to a page with many other links, I'm lost.

I have read that if csrss.exe is using high CPU this can be due to a corrupt profile. The fix for this is to make a new profile, copy all your data from your My Documents folder over to the new profile, and then delete the old profile.

when you say profile, is that the same as "user" on my start button where it says "start - logoff - switch users"??

so I would make a new user?

Yes - that is correct.

Create a new user, and then log onto that user and see if the problem goes away.
