CPU Runs At 100%... Why?

My son has an older Dell Dimension 4550 desktop. I looked at it recently and it's constantly running at 100% and extremely slow. What's causing it is cisvc.exe which is at 98-99% all the time.

What is cisvc.exe? Can I get rid of it or at least adjust it somehow? Also, are those "speed up my computer" products advertised on TV any good?

Thanks for your advice.

I would not use any of the speed up my pc services as found on tv. Most of them will cause more damage than good.

As far as the cisvc.exe - it is a vital part of xp and disabling it could cause many programs to not run correctly.

Have you recently installed the Windows Search 4 feature? It is possible - that if you have a large amount of data on the machine - that the indexing service is constantly running. This will continue until it completes. You can try to disable indexing and performing other tweaks to see if this speeds up your machine by following the instructions here.

If these tweaks do not help - I would be more inclined the think you may have some kind of malware infection. If the previous steps did not help you - Please visit the malware forum and follow the instructions at the top. Start with the instructions HERE! These self-help tools will help you clean up 70% of problems on your own.

If at the end you are still experiencing a slow machine come back to this section and well see what else could be the root of the issue.

cisvc.exe is associated with indexing or a infection.
I suggest turning off Indexing and see if the resolves the issue.
Happyrock what do you think?

I would start with turning off indexing 1st. Its a resource hog.
Then look at the processes as Happyrock is looking for.

After that we can continue to other solutions.

if cisvc.exe is in fact the guilty party you can end the process using the task manager...if it respawns its probaly a infection
