Computer suddenly very very slow

Posted on 2004-04-28
Last Modified: 2010-04-12
I have a Dell Inspiron with W2K installed. It has been superb for about 3 years. Snappy and reliable. I have 384Meg memory (900 virtual) and about 10 Gig free disk space. Suddenly a couple days ago this computer started running painfully slow. The CPU usage is nearly 100%, even after rebooting (which I have done more than a dozen times). I have always run up-to-date virus checking tools, and have done a complete scan of the drive (it found nothing). I've run AdAware and turned up nothing. I can't see any obvious culprits in the list of processes. As it is now, I can barely launch explorer and notepad. I've uninstalled anything that is non-essential.

Until a couple days ago, I would run several applications at once and zip around easily. This is a nightmare! Am almost out of commission. Am trying to shift some of my work to another computer, but as you know, that is not so easy. Any tips, suggestions, ideas, or even calming words would be appreciated! Thanks!

Hi cascade99,

Please check the Task manager to find out what process is hogging up all the CPU time.

Try doing these

a) download msconfig from here and dictate the startup programs
install it , run it . go to startup tab once it runs and disbale all applications. Reboot the machine and check if it would work sooner. There could be some unwanted application that starts during the bootup and might be using the CPU.

b) Download the latest patches and security updates .

c) Check for unwanted starting services and disable them

d) Try doing system file checking ( start ---> run --> sfc /scannow)

e) Have you already done defragmentation and Disk cleanup

f) go to start --> run ---> typein : %temp% and remove all the files inside that folder.

g) You may also want to run other spyware tools in this post http:Q_20945897.html ( post log from hijackthis)

h) Try using this to check which one is consuming more usage

there could be other suggestions that I might be missing. You may want to use recovery console if nothing of the above helps.

Check for malware/spyware -  someone around here has a big list of tools-  a small one can be found at

I agree that you need to find out what is running.. what process...

Download Codestarter after running Spy bot (my preference) or which ever
This software will tell you what is loading when your computer is starting up.... and what process are running.. with descriptions and companies that make it
I have found it very useful in cleaning up an infected machine.


download stinger  ... this is an one shot hard clean by network associates...

Sunray gave me a lot of things to try.. and I have worked through most of them. True I have learned a lot and cleaned up a lot of messes. In particular, Spybot S&D found a lot of nasty stuff. Plus I have cleared out many unnecessary services and programs automatically starting up. So I have a healthier machine...BUT

Unfortunately, the problem is still bad. From the moment I boot up, the CPU time is anywhere between 50 and 100%. Here is the report from HIjackThis. I am desperate to get my machine restored.. so I am still hoping that you (or someone) have some more advice. I can make the machine available through NetMeeting.

First of all, Sunray's help has been fantastic. I'm not completely out of the woods yet, but things are essentially good enough to use my machine again. Many, many thanks. The Codestarter recommended by TeleTech was very helpful too. I cannot believe how many hours I've burned on this. My analysis is that the problems were all about spyware, and perhaps nothing to do with viruses. I use NOD32 for virus checking and none of the other virus checking tools found anything else. But for spyware, I think (but am not sure) most of the credit goes to Spybot. It found a lot of things that AdAware did not catch. Then cleaning up everything questionable revealed by the other tools I think was important too. There still seems to be more processor time taken up than there should, so I guess the job is not finished. To answer Sunray's last comment, I also thought the Placeware one was fishy, and got rid of it. The nod32 ones are fine. I've been running that a long time. I will award 80% to Sunray and 20% to Teletech. Thanks again! I'm sure I'll be back on this topic. What an ordeal!
