vinyl calibration issue

Hi everyone,
I'm experiencing some trouble with the calibration of my timecode vynils..
sometimes it doesn't succesfully calibrate and then out of nowhere it does..or somtimes also while I'm spinning, the "quality" of the decks goes down from 99 98 97 to 80 bringing shitty sounds and difficulties in controlling the track...sometimes it stops at all and I have to recalibrate or to do the install wizard again..and if this happens while you are performing is not cool..the scary thing is that is completely random somtimes I spin for 2 3 hours with no problem sometimes after 10min playing this problem came out;
thank for your help..
p.s. I already optimized my laptop to perform with digital vinyl and to decrease latency
