Query: what a lemon!

Hooked up new a1700n with new HP 19" flat screen. Tried to burn Recovery Disks but failed. HP said to try other compatible brands. They didn't work either. Ruined 5 DVDs. CD/DVD burner making weird noises. Thought I had better put in my backup DVD disk in case and it chewed it up spitting out a broken part. All data lost. Waiting on HP to send new burner so I can make a backup. Installed correct extra 1GB RAM and memory bank #4 is dead. Need to get burner delivered so I can make new backup of data so I can return this system. System is slow and underpowered for Vista. NVidia card has terrible Vista drivers and fails miserably.I can't wait to return this!
