Whats good homies?

I dont know whats happening but i've been getting a lot of usb cut-outs and i'm using my "good-port." It used to light up to orange and sometimes red but this time its cutting up the track and i'm getting pretty frustrated.

Here is a checklist of things I've done to try and solve this issue but nothing works:

- I updated serato's software (1.8)
- updated 57's software
- updated OS X software (still using tiger cuz i'm scared of leopard)
- turned off the airport
- cleaned my needles
- used new serato vinyls

What the heck do i do?

PLEASE HELP!!!!!!

Thanks a lot!
