*wonders how you got that snap*
After looking around the net I have come to the conclusion that this is a false error and he may be just testing us. However, it is possible that he made note of the error type and found a picture similar to it.
My reasoning is this "http://www.pcstats.com/articleimages/200409/BSOD_2.gif" is where his file is hosted from. This is a computer aid site. here is an identical picture

Furthermore, there is no wxyz.sys on either my xp or vista pc. Might be on ME but I doubt it.
If it's real I suggest updating your drivers or doing a total reinstall of co and if all else fails windows, if you recently been getting BSOD errors.
Edit: sorry, apparently it is real i was sitting on the site too long

ps: Had some things to do, didnt refresh. try reinstalling co and stuff.
