Hard Crash Help

[Guest]

I'm at my wits end, and I hope that someone here can point me to a KB article
or offer some insight into what is happening.

I'm running a pentium 950, corsair xms2 ddr2 ram, x1900xtx, soundblast x-fi
platinum. Nothing is overclocked, running windows xp sp2 fully patched. All
drivers updated.

The issue is simple, Windows does a complete hard crash on me, no mouse
movement, no alt-tabbing, just completely stops. On a reboot, Windows does
not complain that it shutdown unexpectedly, there are zero error logs, and to
make matters worse, I can completely reproduce this issue, but I can't for
the life of me track down the problem.

I can be using my computer playing world of warcraft for hours and hours on
end without an issue; but, if I alt-tab out, and start up IE, Windows will
freeze within 30 minutes. If WoW isn't running and I start up IE, Windows
will freeze within 30 minutes. I use firefox, windows does not freeze. When
I use Ventrilo (VoIP application), Windows will freeze, when I use the Vongo
movie service, I can download and watch movies fine, but if I do their live
streaming, windows will freeze. If I use the bit-torrent downloader for wow
patches, windows freezes. Its not a heating issue, and I can't for the life
of me believe its a hardware issue since I can play video games without
issue, use firefox without issue, etc. It would appear the issue is related
to streaming, but I can't find anything even remotely being reported like
this as an issue.

Any ideas?

Try this MS app

On reboot start the app and then run IE through the app, when the crash
occurs Depends should show at what point.
I would suspect video driver
