IE shuts down without warning
This is generally a video driver issue or hardware issue. Try reducing, and
even turning off hardware acceleration at control panel, display settings,
advanced, performance to see if that stabilises your system. Make sure your
video drivers are up to date. Reducing resolution and or colors may also
help.
Also, it can be an overheating problem. Try running the computer with the
case off for a little while and see if the problem goes away.
Sometimes you may have a corrupt IE cache; create a new one as per the
instructions at the URL below:
