this appears to be a RAM module issue after reseating the memory modules the computer was able to boot and all peripheral was functional  
Last week while randomly updating my Aurora R8 there was a Bios update after downloading and being Prompted to restart and I did, my computer would start but the is no signal to my Monitor, Mouse or Keyboard. So, I contacted Dell Support and after a Power down hold for 30 seconds and a reseat the Graphics Card the Technician said it was a bad motherboard and he would send a technician out to replace it. Today the Technician showed up installed the new motherboard and got it back running so i go back to Alienware support and run a full Diagonostic and of course I have 2 new driver updates I installed the first one the Alienware Universe Update no Issues then it prompted the Aurora R* bios update again I installed it then it prompted for restart, and I did now I have power can hear fans running  but no mouse No keyboard and no monitor? I can't believe that this Bios update is destroying motherboards. Anybody had a similar issue? What did you do to get going?   Looking for your thoughts?
