System using 100% CPU

I've got a 2.39GHz AMD Athlon 64 system with 2GB RAM running XP MCE. It's running really slow, so I am trying to clean it up. I deleted all unneeded programs, ran a Spybot scan, and used Ccleaner to get rid of the trash. I notices that SYSTEM is consuming 100% CPU usage all the time. What could be causing this?

Open task manager or better yet install microsoft process explorer and see what process is using your resources....

Sorry, I didn't explain well. In the task manager the process "System" is consuming 100% CPU.

Yep, I just downloaded it, but it's going to be an excruciating slow process to install. I'll report back when it's there.

that is not good, could you also check eventviewer logs for errors or warnings

Oh, one piece of information I wanted to include, is this issue is present even in safe mode.

Searching some more, I found this thread. I haven't read all the posts yet, but there are a few things here, I'm gonna try.

Yes, interesting thread.

Try disabling Microsoft Automatic Updates and see if that makes any difference.
I believe its seeking for or attempting to install or load updates has caused this issue in the past.

Just a thought.

Seems unlikely that Auto Updates is involved.

The 'system' process is for running kernel-mode thread-based activity; this includes driver activities that shouldn't be done at device interrupt level, and stuff such as writing modified pages out to the disk.

My guess you have an insane device or an insane device driver.

Auto Updates is AFAIK mostly user-mode activity, and the 'system' process doesn't have a user mode piece.

Proces Explorer gives a little more info about some of this (but not much).

Do you run any Distributed Computing projects? SETI, Folding, etc? They use 100% when you are not using the PC.

I just went through the same issue myself. I have a HP 1410 that had been exhibiting the same symptoms that you describe. I went to HP's driver site and started updating my drivers. As soon as I updated the video driver the problem went away and has not returned.

Good Luck

But presumably in that case, the CPU use is ascribed to the particular process and not the 'system' process.

My error. I missed that on first read.

Check CPU temperature.
Could be a dead fan or badly seated cooler.
This was the problem on more than half of computers I encountered with 100% CPU problem.

Well thanks for the try guys, but it turns out that I didn't give you enough information to help me find the answer.
There was an issue that I thought was unrelated. USB devices were not recognized by the system. For example, if you plugged in a USB optical mouse, the light wouldn't turn on, and the system ignored it. When I looked at the device manager, all the USB hubs showed no problem. So I thought it was a separate issue that I would address, once I got the system working a little better. After reading through that other thread, I found that USB issues were the cause for some people. I disabled the USB ports in the BIOS, and the problem went away. I think that I may have a H/W issue with the USB controller, but I'm gonna try reinstalling the mainboard drivers.

Turn off and disable Telephony (unless you use it).

go into control panel -> administrative tools -> services.

ive seen telephony cause this exact issue, as well as windows updates background manager.

Try going Task Manager then go to PROCESS tab, sort it by CPU usage. You should see the task that is using the highest CPU usage. Most of the time, if it's a non-system task, you can right-click and end the process. Good Luck!

He knows already which process was consuming CPU. It's the 'system' process, pid 4.

You think so. Isn't there just a way to reinstall the USB controller drivers. I don't mean reinstall the device. I mean remove the drivers, as in delete them. Then reinstall the drivers.

I'm actually thinking that it might be a hardware issue. Like the USB controller is on the fritz.

If you use process explorer it breaks it down even further. But I have also seen an HP system do this and process explorer still didn't reveal what was using the cpu time. But for anyone experiencing this problem, they should still check out process explorer in case it can point out the problem.

Well, if you backed up your registry prior to cCleaner being run, you should restore that registry. If that does not work, then you forgot to tell us something.

Reinstalling XP will probably will not help you.

This seems like the point to tell people that if it ain't broke, don't break it, but maybe not...

Thank you! Now, about that registry backup file....

You did back up your registry before allowing a program to change it, right?



Rexter

Yes, always. The reason that I ran Ccleaner in the first place was because "System" was consuming 99% of the CPU. That would be why the system was running very slowly, as I stated in my OP. So restoring the registry to a point where I had 100% CPU usage would be unproductive. We determined later in the thread that communication with the USB controller was the cause. I tried reinstalling the device, but the system would freeze when I tried to uninstall it in the device manager. I had to disable it in the BIOS. As soon as I enable it, the problem returns. I tried using system restore to take the system to a point previous to when the issue started, but that made no difference. After all this, I suspect I have a H/W problem. The only other thing, I can think of, that I'd like to try, is to delete the USB drivers, and reinstall them, but I don't know how.

This is quoted from a Dell help site, I believe. I don't have the link, I just copy & pasted this once to keep for my own reference:

---------------------------------------
USB Emulation:

USB Emulation determines whether the system basic input/output system (BIOS)
controls Universal Serial Bus (USB) keyboards and mice. When On is selected, the system BIOS
controls USB keyboards and mice until a USB driver is loaded by the operating system. When Off is selected (the default), the system BIOS does not control USB keyboards and mice, though they function during the boot routine.
Set USB Emulation to Off if you are using a PS/2-compatible keyboard and mouse.
---------------------------------------

Don't know if that's of any help to you or not.

There should be no reason to delete the existing USB drivers in place. They can be fully replaced with the newest versions.

I provide complete links to anyone needing to rebuild the USB Stack and other considerations, here:
»aumha.net/viewtopic.php?f=62&t=28888

Note the following from that article:

Install in this order:

USB Reliability Hotfix -- (Brand new driver set for USB)
»support.microsoft.com/?kbid=918005

USB Driver Performance Update (3/6/2008)
»www.microsoft.com/downloads/deta···yLang=en

If the Hotfixes are not applicable, you will be told.

Best regards,
