CPU 100% usage due mainly to explorer.exe

[he llo]

Hi,

I have a problem for over a week now. After logging on, the computer
will still seem to be perpetually loading something. My computer
would then hang. I can still move my cursor but no icon will respond
to any clicking. I have spybot installed. But I can't run it
either by clicking on the icon or going to the Start button because
the computer simply does not respond. The task manager shows
explorer.exe with 97% cpu usage and the total is 100%. I can't even
go online to get a antivirus scan because clicking on the my ISP icon
brings no response either.

I am very desperate. Please help if you can.

My computer is a HP Pentium 900mhz, 384 MB ram.

When did this first start happening?? Did you install something??? Have you cleaned your browser lately from temp files??

If you have spybot thats cool..but get Ad-aware too. http://www.pcworld.com/downloads/file_download/0,fid,7423,fileidx,1,00.as

What operating system are you running XP I presume?
If so I would get more ram. 512 would be better

If you can get your puter to get online try going here and running a free virus scan
http://www.symantec.com/cgi-bin/securitycheck.cgi Just say yes to the 2 files that want to install and leave your puter alone during the scan

I know Im throwing alot at you but we could use some more info from you ..

would post an answer here for a fix????

Yep, I have the same problem.

I have a new XP install (well, second, actually, as I
couldn't resolve this the first time I found this problem,
so rebuilt from scratch....); 2.2G P4; IDE Promise RAID1;
512MB 233MHz RAM. Most clear symptom of the problem is:
Task manager reports that explorer.exe is chewing up
around 99% of CPU time all the time, and mem usage
thrashes between 70 and 120MB; over time, this is climbing
through the roof, and starts to push my page file way up
in size. I can recover the system performance by "end
process" on explorer.exe, but it deteriorates quite
quickly. (30 mins or so....)

This is XP Pro, running SP1 and all the current patches
from the MS download site.

It has NAV 2003 and Zonealarm running on it. Disabling
autoprotect in NAV makes no difference. It has Office XP
Pro; once again, current level of patches from MS.

I know the hardware is kosher; have an identical system
running SBS 2003, that runs like a cut cat!

Would certainly appreciate any clues on this one!
