Average Explorer.exe 5% CPU Usage With No Running Programs?

Windows 2K Pro: Should explorer.exe be consuming 5% system resources when no programs are running?

It seems to me this condition is not normal for my PC. I run my machine with a lot of services disabled, so I believe that an excess of running services is not the cause.

I've run the TaskInfo program to look at explorer.exe threads, and it appears the SysPager thread is causing all this activity. I could find no reference to SysPager in a search at Experts-Exchange, and very few references to it on the Internet.

Please help, as this condition seems to be interfering with the smooth operation of some high bandwidth programs.

explorer.exe uses some processor power normally, but I don't know if 5% is normal on your system (processor speed?)

Can you please post the log from Hijackthis => http://www.webattack.com/download/dlhijackthis.shtml 
This way we will be able to see what's running at booting up.

5% is not at all unusual.  Remember that the Windows DESKTOP is EXPLORER.EXE.  So anytime you're logged in and have a desktop on the screen, EXPLORER.EXE is running.

I found the answer myself before receiving suggestions.

The cause turned out to be the taskbar shell tool "Dave's Quick Search Taskbar Toolbar Deskbar" ( http://notesbydave.com/toolbar/doc.htm ). When enabled, the tool increases explorer cpu resources from very low (0-1%) to about the 5% level I was seeing. I think perhaps the last revision of this tool has caused the increase, as I have been running it at bootup for many, many months and did not notice the increase until fairly recently.

BTW, Dave's Quick Search is a very excellent taskbar enhancement and I highly recommend this tool despite the resourse increase, for those willing to accept the slight performace hit.

I am using a Celeron 300A processor running at 466Mhz. Others with more powerful processors would not likely see this level of performance hit.

I consider the comments provided by LucF and jhance to be equally sound and useful as a first response. I would have split points, but when trying to do so the website responded with a "points could not be split for this problem" error.
