Connection difficulties

Hi,
im having problems with my connection. it first happend months ago, i left my timecodes at home and was gonna use flexible mode. this is what i did when i got to the club. connected soundcard to laptop n then output 1 n input 1, played the track and then tried connecting output2 evrything was ok but as soon as the cable for input 2 made contact mixvibes just stopped playing.
this happend the other week again. i first thought it had to do with timecodes. but this time i hade the time codes in and as soon as i made contact for teh final connection it cut out again.tried pressin play and evrything nothing worked. had to quickly remove all the connection and put a cd in the cdj. i restarted laptop used different phono cables and teh same thing happend. i did the same process again and it worked fine.
last week something i have never experienced happend. evrything was working i went to turn the fan on which was by my power cable for laptop, i just nudged the cable and the volume went. evrything else was active n looked normal but no sound. i quickley changed the cables put in a cd, shut down mixvibes restarted it and evrything was working fine. the following day it happend again and i just put the volume up and restart the track. it makes no sense
and once the track was playing backwards.
has anyone experienced this before
