Originally posted as a 50% CPU issue, now evolving the info...
Quick system specs:
- OptiPlex GX280 (3.2GHz/1GB RAM)
- WindowsXP SP2 (fully patched)
- Internet Explorer 7 (fully patched)
Several of us at work have been having problems with IE7 getting jammed up
intermittently. Problem can go for days (sometimes weeks, though not often)
without occuring or can happen several times in a day.
Our original issue was that IEXPLORE.EXE would show 50% CPU utilization in
Task Manager. Further, even after all instances of IE had been shutdown, no
longer appearing in the Applications tab of Task Manager, the IEXPLORE.EXE
process would remain, still at 50%.
End Process is unable to effect IEXPLORE.EXE in any manner. Shutting down
the system usually never completes properly, requiring the power to be cycled
manually.
As an experiment today, I've tried running multiple windows of IE7 without
Add-ons, which had no effect on being able to reproduce the problem.
Interestingly, pages on COMPUTERWORLD.COM seem to cause the most problems,
as I can retrace my steps through Monday's history in IE, hit a few pages
from that site and BLAM!
Here is where things changed... During one of the restarts of the PC
today, I switched off hyperthreading in BIOS. Now when I trigger the problem
in IE7, the CPU starts grinding at 99%. At least with hyperthreading
enabled, the system never allowed IEXPLORE.EXE to get beyond 50% CPU.
This is not a virus, malware, etc.
BTW, this is my second PC with which I've encountered this problem. My
first PC started having this problem months ago, so I tried FireFox 2 for a
while as my default browser. No problems unless IE was triggered. We used
another PC that was similar to my original (additinal DVD drive) yet with
updated BIOS, drivers, etc. Had several weeks of trouble free IE7 use, then
started seeing the IEXPLORE.EXE issues popping up again.
Thanks!!

What if you right click the IE icon on the desktop and choose Start Without
Add-ons?
Or go to Start | All Programs | Accessories | System Tools | Internet
Explorer (No Add-ons).

Frank,
My original post was a little wordy, but yes, running IE7 without add-ons
was no help.

Try these tool to see in realtime which running in the back ground and are
currently loaded:

RootkitRevealer v1.71
http://www.microsoft.com/technet/sys...tRevealer.mspx
Turn OFF Windows Updates and BITS in serves.msc services control panel,,
also what your Anti-virus/firewall arrangement?, run a through scan, search
your system for the occurrence/presence of IEXPLORE.EXE. How many and what
the properties of it show, does the info add up?.
You may having a memory leakage and this can be hard to trace/track down.
Run this command:
sfc /scannow

This reply took a while, but I wanted to run with my change for a period of
time before posting what I learned...
Every time the browser had an issue, I noticed that the Phishing Filter
icon at the bottom of the browser window was buzzing continuously.
So, instead of going through all of those diagnostic gyrations, I disbaled
the phishing filter in the Internet Options, under the Advanced tab.
After that, I have not had a problem since.

Do you have a security suite installed that includes its own Phishing Filter
(e.g, Norton; McAfee; Trend Micro)?

Is the machine fully patched at Windows Update?

The PC has always been fully patched via Automatic or Windows Updates.

As for phishing, we do use Trend Micro OfficeScan, but I do not think it
covers web browsing per se. We do have corporate firewalls that block access
to certain sites based on various criteria. Besides, IE7 would crash on
ComputerWorld.com, hardly a site that should be an issue, but is was.
