rbdj not stable

if that's the case ,. why isn't my i 7 5700hq 16GB 1 TERA laptop isn't keeping rbdj steady . i have set to high performance , i have nothing else in the laptop except serato and win 10 OS . I have 1066 tracks and i have aslo deleted I Tunes so that to make sure the laptop is not sharing any other prog . i don't use this laptop on for internet , the wifi has been disabled and even the anti virus which i bought . i run and scanned the cleaned the pc and i finally uninstalled it . so now my laptop don't have antivirus in it and i think that will aslo eliminate any posiblility of software conflict with rbdj. i also did a tool check and defrag the laptop . everything is ok , but yet rbdj spiked unexpectedly while on test at home . and tonite i don't know whether i should trus rbdj or just click on serato n do the show.
