need some helpful information...

hii
i am using vci 100 with a dell laptop and sometimes the computer has issues:
restart itself or stuck etc... as a result it stops the music.
are there any solutions to avoid this?
the problem is not in a specific computer but in general every computer has its issues , there isn't a perfect computer that never stuck or something like this...
there must be a solution to insure a smooth continuously play of set.
what do u do in cases like these?

thanks
