New Bluescreen Problem

Well, I've been getting this wierd glitch lately. Sometimes (pretty
rarely and randomly, only twice now) in Guild Wars, I get a BSOD
crash. The first time, it happened when I tried to log out. The second time, it happened when I tried to exit the game. "Page Fault in Nonpaged Area," something about nv4disp.dll (nVidia driver file), and this error left in the event viewer:

The computer has rebooted from a bugcheck. The bugcheck was:
0x10000050 (0xe57c7324, 0x00000000, 0xbfa8b7c8, 0x00000001). A dump
was saved in: C:\WINDOWS\Minidump\Mini062005-01.dmp.

Same memory references same both times, which, from what I read, can indicate a software issue. I did recently update to the 77.30 drivers from nVidia, which is about the only thing I've done in the last week (before which the game ran fine-n-dandy.) Could that be the culprit? Any idea what might be up?

I believe Battlefield 2 updated 77.30. 77.30 is in b and is very buggy. Switch back to 71.89. This happened to me and my computer restarted everytime I close Guild Wars.

Alrighty, I'll give it a shot, thanks.

EDIT: On another note, I just noticed, the 77.30 drivers aren't even on nVidia's website. Must be alpha drivers or something :P
