Cd/DVD reader stops working after a while

I just bought my laptop, a new toshiba satellite with windows 7 and 64 bit, i tried to install assasins creed 3, but gave me error about "feature transfer error component sound_sfx file\data2.cab error data error (cyclic redundancy check)", i thought it was a game error, but then i realized my dvd reader stops working, i tried to copy the files from the dvd and it stoped working after a while also (it happened with abother DVD too when tried to copy the file to my computer). So i was wondering what can i do, please help me!

Just to make sure that you are not trying some prohibited actions :), which may result in your optical drive not complying with it, play some audio CDs and Video DVDs, write a CD-RW and DVD-RW and check whether it works fine.

If not, activate your warranty for a replacement.
