Several of us have been having problems with IE7 using 50% CPU at work for
several months now... sorry if this is a bit long.
In an effort to try and get away from this problem, I recently set-up
another newly configured PC, after which it started showing up again within
several weeks in production.
Problem occurs intermittently and not easily reproduced, though it happens
more than we'd like. Can go for days without occuring at all or can happen
twice in one afternoon, like today.
In Task Manager, IEXPLORE.EXE will be running as normal and appear to be
bouncing around at 60-70% CPU in Task Manager while Internet Explorer is open
(multiple windows, mutiple tabs, etc).
Closing tabs, then entire windows of IE never brings the CPU below 50%.
Now IE is totally closed, it's no longer listed in the Applications tab of
the Windows Task Manager, but still chunking away at 50% CPU in the Processes
tab.
Other issues that seem to coincide:
- most other apps appear to be stable and can be shutdown normally without
issue until Apps tab is clear;
- Lotus Notes will almost always hang or fail to completely shutdown,
though never goes into the "Not Responding" mode within Task Manager.
Usually stays as "Running" even though it's definitely no longer working
(half closed).
Lotus Notes is usually where I notice that my system is making #2. Often
I will click on a URL within an email message that gets passed to IE.
Often IE will gag on the ComputerWorld.com site, though it's not
exclusively the site that will cause IE to go into this mode.
Another kicker: no matter what, I can not get rid of IEXPLORE.EXE using
the "End Process" button in Task Manager. Though IE is no longer running,
that process stays and keeps eating CPU at a steady 50%.
I've seen other posts similar to this, but never found a resolution posted
or an idea of what is possibly causing the problem.
Microsoft has a few dozen "This program is not responding..." dumps from
me between IE and Lotus Notes, related to this issue.
By the way, I never once had this problem when I started using FireFox 2
as an experiment. That isn't a dig at IE per se, it's a clue. I installed
FF2 on a prior PC with which I was having the same exact issues and started
to only use FF2 to surf the web exclusively. The only time the IE issue ever
came up was when I spaced out and clicked on Microsoft Update which triggers
IE to open. Blam! 50% chance I was going to get a 50% CPU issue.
This isn't a spyware, malware, trojan, virus, or rootkit issue or it would
have manifested itself in the use of FF2 (several months) as well.
I think that Lotus Notes is a red herring, as much as I'd like to blame it
for my problems... we have almost 200 people using is in similar configs to
mine. BTW, I'm running a Dell OptiPlex GX 280 (3.2GHz/1GB RAM), Windows XP
SP2 and IE7, all fully patched. This is my second PC to experience this
issue. Though it's the nearly the same hardware config (new one has a DVD
drive), it was built using a new image.
Anyone have any ideas...?

Try closing other apps as well then. For example, I have seen a related
symptom with OE windows which might have originally been used to start
an IE window.

That doesn't follow.

Is Lotus Notes being used to launch IE? Perhaps you are seeing a similar
effect to what I have seen with msimn.exe. E.g. there may be no IE window
apparent (with the same PID) but when I close an OE window that instance of
iexplore.exe finally disappears.

If that's the case as a test try avoiding that function in Lotus Notes.
E.g. only copy links from its documents and open them separately.
If your symptom changes it would likely be due to the change in function
that you were causing manually.


Good luck

Robert,
First off, thank you for your reply!
I had not yet checked this thread today before trying an experiment...
Restarted my system this morning by manually powering it off (still hung
during shutdown at the "Closing Network Connections" section from last
night's adventure) and powered it on again.
In Windows, Word2003 and Task Manager were running when I started two
instances of IE7 without Add-ons.
One window had 7 tabs loaded with our company's different web sites, as
set in the Home Page options. In the second IE7 window, again without
add-ons, I opened my History and went right for yesterday's COMPUTERWORLD.COM
activity.
Within 3 pages, I had one of the two IEXPLORE.EXE processes chunking at a
steady 50% CPU. No Lotus Notes running, not even started on this box since
rebooting...
Interesting.
BTW, one of the guys next to me who is also having the same problem tried
what you suggested and was copying links from his email into a browser
window. Did not prevent the problem from happening.
Are these forums moderated by Microsoft?
Anyone from the IE development team?
Like I said before, we've been at this for a few months with IE.
Thanks!

Michael

Can pretty consistantly reproduce the 50% CPU issue with IE7 now by just
running through the three COMPUTERWORLD.COM articles that I veiwed on Monday,
again IE7 is running without Add-ons.
Tried another step in the experiment...
When logging into WindowsXP, I held the SHIFT key down, suppressing
certain items from starting when the profile loads. At this time, I'm not
totally sure of everything that is missing from a normal startup.
The failure was not able to be triggered in this one time that I used this
startup method.
Restarted the PC and logged in as normal. Opened up two windows of IE7
without Add-ons and reproduced the error again by navigating through Monday's
history.
Restarted the PC again and used the SHIFT logon method. Opened two
windows of IE7 without Add-ons. While the first window had not yet fully
loaded all of the normal tabs assigned in the Home Page options, I fired up
the second IE window, upon which the second instance failed to fully start.
One of the two IEXPLORE.EXE processes went immediately to 50% CPU. Was able
to shut down the first window of IE without issue, except that it remains
listed in the Processes tab of Task Manager.
One instance of Windows Internet Explorer remains listed in the
Applications tab of Task Manager, though it doesn't respond to closing the
window by using the X in the upper right corner. Had to use the "End Task"
to stop the application, triggering the "The program is not responding"
process. Gladly sent the error report!
Both processes of IEXPLORE.EXE remain in the Processes tab, one at 50% and
one at 0% CPU.
Restarting the PC yet again...

Then you may be able to refine that test by using msconfig

BTW there are known interferers which can not be blocked by
No Add-ons mode. Google's toolbar is one example, so it would
be the first thing I might try disabling. Also, other products have
preload programs in Startup, so you could have been suppressing
other things you aren't even aware of which aren't essential anyway.

Check with netstat to see if there are any residual connections which
might be hanging that task. E.g. in a cmd window enter:

netstat -ano | sort /+70
and
tasklist /fi "Imagename eq iexplore.exe"

Before doing that check with Task Manager (or Process Explorer)
some of the other statistics. E.g. is there any I/O activity too?
If so, you might get some clues from ProcMon. For that matter
ProcMon could give you the Stack for the task when you used
the End Task command. Also taskkill /IM iexplore.exe /f /t
might succeed where Task Manager's End Task fails. ; )


Good luck

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.
