High CPU Utilization Problem!! Pls help

[Dr Andrew Teoh]

Dear all,
I'm running XP SP1 +all updates, 1.8Ghz P4, 1GB RAM and Norton Antivirus.
Everything starts up nice, seems to work like it should. But when I try to
start Windows Explorer, it won't launch, and explorer.exe goes to 90% cpu
usage. Goes a little down if another prosess uses alot of cpu, but it comes
back to 90%, nothing more or less, and no explorer starts. But I can browse
my files through Nero's browser, and everything is just fine, or with cmd. I
tried to start internet explorer, that works, and then i added the button
for showing folders in IE, but then both iexplore.exe and explorer.exe goes
to 50% cpu usage each, but it shows me my files and lets me do what I want
in explorer through IE. explorer.exe is just normal when doing this. I
noticed that some keyboard shortcuts didn't work, like ctrl+c for copy, or
pressing Del or F2 for renaming and so on. I had to right-click with my
mouse and select my action there, that worked... If I shut down
explorer.exe, and restarts it again, it's normal, but when trying to open
windows explorer, nothing launches, it just uses 50% cpu again. I've tried
different virusscanners, spyware-removers, trojan-removers, SFC and so on,
and I found something that I removed, but it hasn't solved my problem. I',
beginning to get pretty frustrated here, someone that can help?

Regards
Andrew

Hi,



To see what programs/services are accessing your drives, try File
Monitor
http://www.sysinternals.com/ntw2k/source/filemon.shtml
it may give you way more information than you can digest - work on
filtering out known, safe things.

Good luck

I am having the same similar problem. A few minor differences, 128MB Ram, Gateway Laptop, OS updates current, AVG antivirus software current. Manually shutdown at bootup almost all services. Even tried "Last Known Good Configuration" but to no avail. When starting in safemode, the problem doesn't exist...Does anyone have any ideas?

I am having exactly the same problem
SP1a and all additional fixes have been applied
Am running the latest Sophos anti-virus (with all current IDEs) which shows a clean system
I can run IE though
It also appears to do the same if you open MM

I have thoroughly search technet but to no avail

Can anyone shed any light on this???
