CPU always stays at 100%

Hi,
My CPU is always at 100%. I have run various spyware programs and have had no luck getting CPU below 100%. The SYSTEM Image Name always makes up the remaining %, therefore, even if I delete all of the running programs, it still stays at 100% because SYSTEM will take up all of the CPU. Although I don't think I have any viruses (but I could be wrong), here is my HijackThis.log. I have searched many different forums for the last few weeks, but I have still not been able to find a solution.

Any help would be appreciated.

Hello locust1937,

This is not the malware forum, please do not post a HijackThis log here.


100% CPU can be cause by many different things. We will go through each possibility/solution until we find the right one. Please have patience with me as we do this, since it could take a while. But I will help you get this problem solved :whistling:


First possible cause could be a corrupted or full index.dat file. We will use CCleaner to fix that.

Download CCleaner from http://www.snapfiles...t/ccleaner.html
  • Install it. Then start the program.
  • In the area designated as "Cleaner Settings", Make sure the Windows tab is the selected tab.
  • Under the category of "Internet Explorer", UNcheck all boxes except for the first two boxes (Temporary Internet Files and Cookies) and the box called Delete Index.dat files.
  • UNcheck the box next to the category called "Windows Explorer."
  • Under the category of "System", UNcheck Empty Recycle Bin.
  • At the top, click on the tab that says Applications.
  • UNcheck EVERYTHING! If there is a category called "Firefox", then leave the Cookies option checked.
  • Now click on Analyze. When it is done analyzing (it could take several minutes since this is your first time using ccleaner), click on Run Cleaner.
After it is done deleting the junk files, including index.dat, restart your computer. After it has restarted, see if the problem still occurs.


If that didn't work, let's move on to Tune-up:

Download and install Tune Up 2006 Trial

Click on Clean up & Repair. Run TuneUp DiskCleaner. Delete all junk files. Afterwords, return to the Main Screen.

Click on Clean up & Repair. Run TuneUp RegistryCleaner. Fix all errors. Afterwords, return to the Main Screen.

Click on Optimize & Improve. Run TuneUp RegistryDefrag, which will take a few minutes and need a reboot.

After the reboot, start Tune Up again. Click on Optimize & Improve then click on TuneUp System Optimizer. Now click on Accelerate downloads and Internet surfing to accelerate downloads, select the speed just above your actual connection speed, this requires a reboot.

After the reboot, start Tune Up again. Click on Optimize & Improve then click on TuneUp System Optimizer. In the menu to the left called "Wizards", choose System Advisor. Note some of the advice it tells you.


If neither of those 2 programs worked, do this:

Download Process Explorer from Sysinternals
http://www.sysintern...ssexplorer.html

Extract and run it. Go to VIEW > SHOW Fractional CPU usage
Make sure it is checked.

Look in the CPU column and relate what is consuming your CPU time

If you can, a screencapture would be useful.

question: would setting the priority of a task to realtime cause the cpu to run at 100%? i didn't think i should make a topic just for a yes or no answer.

@ TaNkZ101: Not quite sure what the realtime setting is. I know what you're talking about, but I've never researched it. Search with Google and see if you find the answer, and then, if you find it, post it so you will teach me something :whistling: I just set 2 of my programs to realtime, no change in CPU. My guess is your situation is not normal.

@ locust1937: Amazing...let's find out what the heck your computer is doing when the CPU goes to 100%. Time for me to collect some technical information from you :blink:

Please download filemon. After downloading, unzip it to your desktop.

Before we get started, I want you to be familiar with the Capture button so you can find it quickly when we do this. Open Filemon. Note the button at the top that looks like a magnifying glass. Pressing that button will stop Filemon from recording (capturing) the activity of your computer. That is the button you will be pressing when I say to.

Now exit out of Filemon. Exit all non-essential programs (the ones in the taskbar next to the clock. Do this by right-clicking on them and selecting exit or close.)

Figure out how to cause the 100% CPU at will, unless it occurs all the time.

Now we will use Filemon.

We are going to do this fairly fast: Open Filemon and then immediately cause the 100% usage problem. Let the computer sit for about 10 seconds. Quickly return to Filemon and click on the magnifying glass button at the top. Now click on File > Save as... and save the log to your desktop. Attach that log to your reply to me.

NOTE: the only reason for doing this procedure so quickly is to minimize the size of the log so I can pinpoint the problem. Also, you may need to compress (zip) the log because of it's size.

That was way too short of a log :whistling:

Did you let it run for at least 10 seconds? If so, are you sure the CPU was at 100% when it was running?

Note: you can minimize Task Manager to the system tray and the chart that you will see in the tray is the CPU usage.

sorry, I didn't let it go for the full 10 seconds. This file should be a bit larger. I am positive about the CPU of 100%. It never varies from 100% CPU, even if I get rid of all running processes.

Very interesting...

It looks like you got some corruption of your OS. Your computer is accessing a bunch of different DLLs, ones that are legitimate, but it is accessing them when you don't need them.

Either
1 - They have become corrupted <or>
2- A program that uses them has become corrupted


My Suggestion
Go to Start, Run, type sfc.exe /scannow and press enter. You will need an XP CD for this. Let it run to the end. It will automatically replace critical Windows files that are corrupted without prompting you. If you have any problems running this, check out the following link: http://www.updatexp....cannow-sfc.html

Reboot when it is finished to see if it worked.

I ran the sfc.exe /scannow and, unfortunately, I am still having the same issues. As always, I notice that the CPU is always 100%. When I start deleting processes, the SYSTEM Image Name replaces the remaining CPU so it always is 100%. Thanks again for your help.

Run filemon again, but let it run for 30 seconds this time...

And while I analyze it, restart the computer into Safe Mode and let me know if the 100% CPU occurs in Safe Mode.

Hmm...same results...

When exactly did this problem start occuring? Was it after a windows update? Installed new software? Power went out?

Before I make my next suggestion, answer those questions, and let me know how it ran in Safe Mode.

When I boot in safe mode, windows freezes so I am unable to get taskmanager to appear. I tried this 5 times and had the same results. I can get to the desktop in Safe Mode, but then it freezes.

I noticed this happening a few weeks ago, but it may have started earlier. My computer had to be rebuilt after motherboard, hard drive & power issues. Windows was reinstalled. Its been 2 months since I had it rebuilt but was not using it very much until the last 2-3 weeks and thats when I first noticed the issue. Like I said before, it could have started after windows was reinstalled a couple of months ago, but it may have happened after a windows update. I really am not sure.

When windows was reinstalled, was it installed from a full XP CD? Or was it reinstalled from a Recovery CD?

If it was installed from a Recovery CD, then that is most likely your whole problem, since the MB was changed.

Find out what it was installed from, and I'll double-check to make sure that could be the cause.
