Sound glitches in RB

This is my second post about my issue with RB. 

My sound glitches every once in a while. I have this issue since RB 4.xx and everything I tried hasn't worked. It happens in export mode, it happens in performence mode, with a controller, with cdj's it happens everywhere in RB. I've tried different buffer sizes, built in sound card, external sound card and controller but the sound keeps glitches at random moments. 

It happens for a second or something but its very noticable and the crowd notices it too. 

I've used Serato before this and didnt have any issue with it. Its not like my CPU is having a hard time either. I dont see any spikes when it happens nor does my CPU get over 20% while DJing.

Specs:

Lenovo Y50-70-01132

If Pioneer would be so kind to answering this one and not ignore me i would become a happy customer again. Also if Pioneer would be so kind to answer my other post would be a big bonus.
