First off, yes my 'box is modded w/ an xecuter 2.3b lite. While backing up games I realized it locked up, then while playing games it locks up, now i get to the xbox start up screen and after the fancy thing is over...it locks up. After a while i pulled it out of the closet and switched it from slave to master and it played fine, quite happy was I...then it locked up lol. I have a hdd in an old computer but the hassle..not to mention I have no clue what I'm doing there.. any suggestions?
