Got the motherboard replaced, all good now.
Hey All Just had my motherboard replaced last week after only having my unit for a few days. I am at BIOS version 1.1.1 and want to patch it to 1.1.5, but it it won't update. I get the pc to reboot after running the update via Windows or from boot menu. I get the pc start up for about 5 seconds, then it reboots and nothing happens. I am suspecting the replacement motherboard has issues. I did notice in the BIOS logs entries in the motherboard about a month before I had the board installed, so suspect this board isn't new.. Any one know how to access logs to see why the BIOS is failing. Anyone got any I ideas before I spend another week or so getting Dell to look at it or replace the motherboard a second time?  
Aurora R12, BIOS won't upgrade, stuck on 1.1.1
