One of the most common issues that causes this is video card problems.
Turn down the hardware acceleration on that card - Right click
desktop...Properties...Settings...Advanced...Troubleshoot tab. If this
helps, then go to the website of your video card manufacturer and download
and (re)install the latest drivers for your card. Also, get the latest
version of DirectX:
IE puts more strain on your video card/drivers than almost anything outside
of games and CAD/CAM-type programs.

Heat buildup can also cause spontaneous reboots. Make sure all vents are
clear and clean, all fans are running, etc. Also a bad power supply on the
system can cause this issue, or just bad line power. Using an
uninterruptible power supply (UPS, aka battery backup) like the ones fromhttp://www.apcc.comcan help.

Third party programs associated with IE can also cause this issue. Go to
Tools...Internet Options...Advanced tab, Browsing section, uncheck "Enable
third-party browser extensions", click Apply, click Okay, reboot. If that
solves the issue, then it's time to narrow down exactly what is causing the
issue. Recheck the box, Apply, Okay, reboot. Then go to Tools...Manage
Add-ons, and disable a couple at a time to pinpoint the culprit.

If still no joy......

This may be caused by spyware/malware that's gotten installed on
your system.
The problem could be something new that the
spyware cleaners you've used don't have in their databases yet (and I take
it you've updated their definitions before scanning). In that case....

Hi. I hope someone here can help me. On my wife's pc, running
WindowsXP home edition, service pack 2, with Internet Explorer Version
6.0.2, when she is surfing the net, she is on a website (no ONE in
particular, Ebay, yahoo,,etc.) her browser will suddenly close
ITSELF, then the pc goes thru it's normal shutdown procedure (saving
settings, logging off, shutting down) ALL BY ITSELF. She then has to
restart the pc and start all over, bringing the pc up. This happens AT
LEAST once a night and all that she is doing is reading websites. It's
like a ghost takes over her pc, closes the browser, then shuts down
her pc.
I have run Adaware, spybot, windows defender, Zone Alarms spyware
scan, Norton utilities, and Norton Anti-Virus and they find things,
which I then remove, yet still this problem persists. Does anyone have
any ideas, before I format the HD and reinstall everything?- Hide quoted text -

Thank you SO much for your ideas and help. If it was a bad power
supply, wouldn't the pc just shut-down, like a light bulb that burns
out the second that you flip the switch? Rather than having the time
to go through the whole formal shutdown procedure?
