Guild Wars randomly freezes up in the mountains.

Whenever I go the the Shiverpeak mountains when it begins to snow the screen freezes up. Same as when I exit the snow. And occasionly when I'm walking through the map while it's snowing it snows. Now the screen freezes but the action is still going on. I just minimize it and then come back onto the screen and it's fixed temporarily, but it still freezes up. I lowered the quality of graphics and that didn't help, in fact it made it worse. The next time it froze up I go DC'd. This is really giving me trouble in the Iron Horse Mine and I can't complete a quest because of this issue.

Can anyone help?

Try narrowing out the problem, play a bit with the options. I'd send a ticket to support about this issue though.
