New Xbox Problem

[days ago]

hello all, im new on this forum, so hi all. ive had me xbox modded for a while now, and like eveyone had my fair share of teething problems. but now have a new problem which has occured on mine and a friends.
ok here goes, all is running fine until i installed the new 007 game usin the avalible patches and all worked ok, until a new level loaded and then it froze. i then came on this forum to find some good info, and then was told to try and change my PAL xbox to NTSC. i then rebooted, and now just hangs on my boot screen. loads screen then XECUTER 2 appears undearneath then hangs.

my mate done all the same, but he didnt change the PAL or NTSC options, but adjusted the screen resolution in the same xbmp menu. then has same symptoms. hmmmmmmmmm

i havnt a clue, but if this happend to 2 differnt machines in a nite, then im sure this has happend to some one else. im not sure even if the 007 game has anything to do with it, but befor it was installed, i had no prob adjustin pal and screen resolutions.

PLEASE HELP, MY XBOX IS USELESS AT MO
