I had my xbox modded not too long ago, maybe about a week ago, and whenever i play my xbox makes this squeaky noise every 10 ~ 20 minutes that last about 2 seconds, does anyone know what that sound is?? Also, sometimes when I play my xbox crashes in game. Is that because it's running off my hard drive? should my xbox not crash? Do I need a fan to cool my xbox down if I have a 7200 rpm hard drive installed in it? thanks for ALL your guys' help, I really appreciate it.
