My pc started acting funny, slow start up, freezing up.The pc is running very slowly. The mouse arrow seems at times to have a mind of its own. I am also having trouble opening some pages online. For example, I cannot get windows update to work it stays at "Checking for the latest updates for your computer...". I have run Ad-Aware, Clean Up, McAfee and various online scans. Everything comes up clean? The only weird thing I notice is that no matter what program I am running my CPU usage stays pinned at 100%. Any clues as to what could be causing these problems??? Thanks!

Items in blue which are underlined are clickable to give more information about the process

Click start then run, type prefetch then press enter, click edit then select all, right click any file then click delete, confirm delete

Click start, all programmes, accessories, system tools to run disc clean up, then from system tools, run disc defragmenter.

Click start then run, type sfc /scannow then press enter, you need the XP CD

Windows File Protection will show a blue onscreen progress bar, when the bar goes, reboot

If you do not have an XP CD you can borrow a same version as was originally installed XP CD, if you downloaded SP2 then you need an SP1 XP CD

If you do not have an XP CD and are unable to borrow one, run the scan, click skip if it asks for the CD, if it keeps asking, click cancel.

If it kept asking for the XP CD then system files are missing


Click start then run, type chkdsk /f /r then press enter, type Y to confirm for next boot, press enter then reboot.

Windows will appear to load normally then either the monitor will show progress or the screen will go blank, do not disturb this.

This will take an hour or so before it gets to the desktop.

Download and install Tune Up 2006 Trial

Run Tune Up Disc Clean Up

Run Tune Up Registry Clean Up

Click Optimize and Improve to run Reg Defrag, which will take a few minutes and need a reboot. You should disable the antivirus programme to run this and check it is running after the reboot

After the reboot, click optimize then system optimizer to optimize the computer, select computer with an internet connection from the drop down menu, this also requires a reboot

After the reboot, click optimize then system optimizer to accelerate downloads, select the speed just above your actual connection speed, this requires a reboot

After the reboot, click optimize then system optimizer to run system advisor



If there is no improvement

Please follow the procedures outlined here: Malware Removal Guide

You will need a PC which can connect to the internet

Run all the programmes as advised then post a current Hijack This Log in a new topic in the Malware Forum

For the purpose of accurate malware analysis, Hijack This Logs are only dealt with in the Malware Forum. Posting them anywhere else will result in a delayed response

If you are unable to run any of the programmes, please ask for advice in the Malware Forum

When I attempted to do the chkdsk /f /r , the "scandisk has been scheduled" screen came up. It then stayed on that blue screen for over an hour and 1/2 with just 0%. So I rebooted and did not do the scan. Is there something else I should try or should I just move on to the next step of downloading and installing tune up?
The pc is acting much better already! :whistling:

That's weird, and may not be a good thing.

Go ahead with the Tune up directions, since that will give your computer a good cleaning. Can't hurt. :whistling:

And we'll "play it by ear". If it gets bad again, we'll dig deeper. If chkdsk had problems, then that could indicate a failing hard drive. We can investigate that, if you want, after you've completed the Tune up directions.

Failing hard drive! :whistling:
I hope not, I had to replace my hard drive about 2 or 3 years ago. I actually have had that happen before when I tried to schedule a scandisk. If for some reason the pc gets turned off wrong, scandisk works fine though. Ok I will continue with the your directions and see what happens from there. Thank you so much for all your help so far.

Well I tried to download the tune up 2006 but when I try to install it I receive an error stating TU2006trialen.exe is not a valid win32 application! :whistling:

I did run the HD one. I am not exactly sure what its telling me but for the benchmark test the results were:
Transfer rate:
Min. 1.3 MB/sec
Max. 25.5 MB/sec
Avg. 23.6 MB/sec
Access time - 14.7 ms
Burst rate - 27.2 MB/sec
CPU 9.8 %
The Health status came up as OK
and the error scan said 0.0% damanged blocks.
So I guess that is all good?

The pc seems better since doing the first steps of the directions. It did freeze up once when I first turned it on and attempted to get online. I couldn't even get it to shut down. Once I got it to reboot, it has been running pretty good today. Any other suggestions or just wait and see for now?

Sounds like it got corrupted while you were downloading it. Try downloading it again.

When someone says "the problem just went away" or "something happened, but isn't happening any more", that just isn't enough for me. I'd like to know why it happened and will it happen again. I hate just dismissing a problem as a fluke, so let's run a couple more tests and see if we can find out just what happened to your computer, and why it froze up just a while ago. And if everything checks out, we'll just watch the computer and see if all is well.

Speed Fan
Please download Speed Fan and install it.

Start Speed Fan. When it is fully loaded, take a screen shot of the first screen by pressing Print Screen/SysRq on your keyboard. Open Paint and paste. Save the screenshot as a JPEG and post it in a reply to me. Now click on the tab called S.M.A.R.T.. Select your hard drive by using the drop-down box at the top. Now take a screenshot of that as well. Post it in your reply to me as well.

NOTE: For certain computers, Speed Fan will not display accurate measurements. If the temperature wildly fluctuates or doesn't change at all, let me know, otherwise I will believe the mesurements are accurate.

Stress Prime
Download Stress Prime

After you download it, double-click on it (which opens the CAB that it is in) and drag the program to your desktop. Now you can run it. Click on the drop-down box at the top and select Large, in-place FFTs - stress RAM and click Start

If it detects a fatal error, it will stop automatically and then report it. Let me know if that happens.

Otherwise, stop the scan after about 30 minutes, and then in the window at the bottom, it will say if any errors/warnings were detected. Let me know what it says.


If everything checks out with these two programs, and everything is running fine for you, then we'll leave it as is. But if you encounter ANY problems at all, get as much info as you can (such as what you were doing, and messages or errors it says, etc.) and let us know. :whistling:

Tried the tune up install again and received the same error message.
Here are the screen shots
I ran the stressprime and after 30 minutes had 0 errors and 0 warnings.
I downloaded the installer but didn't install that yet.
