Inspiron E1705

My laptop (Inspiron E1705) is 4 months old and has been returned for repairs now 3 times.  Problem is when gets unplugged the screen goes dead.  Only way to get it up and working is to hard boot the machine.  All work is lost.  Dell has replaced the LCD, LCD cable, and now the system board.  The day I got it back I tried it and it immediately failed.... AGAIN !!  Now getting hardware malfunction.  NMI:Parity check/memory parity error.  System has halted message.

Anyone ever had these similar issues?  I am now requesting a new laptop but as of now it's been 3 days and I've not yet heard back from the supv at Dell Support.

Any ideas anyone?

 

Thanks !
