Locking Up Under Windows Xp

<div class="IPBDescription">Sorry if it's already been said..</div> Howdy,
great job, first off. I love NS, I can't get enough of it!

Even with my machine locking up every half hour I still
play for hours on end! <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin.gif' border='0' valign='absmiddle' alt='biggrin.gif'><!--endemo-->

It doesn't seem to matter which race I'm playing, if I
use the compatability mode for 95/98/ME, or anything
like that. There's no specific thing I do to make it lock
up, that I can find. It just locks.

I'm running the latest version of Direct X, AMD Athlon
running @ 1333, 768 megs of ram, Ge2 Mx400 with the
latest nVidia drivers, 800x600 in OpenGL. Running
Windows XP Professional.

Any help you could provide would be most appreciated.
It might be a hardware problem, but I run CS/DoD without
any trouble. <!--emo&???--><img src='http://www.unknownworlds.com/forums/html/emoticons/confused.gif' border='0' valign='absmiddle' alt='confused.gif'><!--endemo-->
