Weird Problems

Ok well I just got my modded Ps2 along with Crystal Chip 1.2 . I also have BootManager installed with no problems , but for some reason when i boot up boot manager i choose minimal mode or w/e it is but it just goes to a black screen and hangs. When i choose Enhanced Mode it says please wait.... and sits there for a few minutes and restarts to bootmanager after wards. can someone help me ? I just tried my burn and i chose minimal mode and it restarted to BM again ... I burnt at 1x speed and it should work but i dont know ... Any ideas? I'm really in need for some help
