Audio problem

Alright so I just started and I'm loading up wav files via zip disk into the MPC...everything is good then like 15 minutes later everytime...when I play the sample there is some static...I turn it off and try again and it's good for another 15 minutes...I mean I think I could get over it...But it's annoying and I wan to get rid of this problem

has anyone experienced this?

It's probably overheating. Do you have the 8-outs installed?

thanks for answering... no I don't have the 8 outs hooked up and it's on for literally 15 minutes when it starts doing this
