Damaged my computer

I installed NIS 2012 on my computer.......First it uninstalled my cdrom, then it crashed my computer.    Norton 360 V5 and 360 V6(trial version) run fine. But I updated to internet Security 2012 and now my computer will not run.  I system restored twice , but now it's dead.  What's the problem with NIS2012? Do NOT tell me it's a windows 7 problem because it's NOT.  Soooo , what are we going to do about my problem?
