I just recieved my new Alienware Aurora-R4 on Friday, May 4.  So far, I've had 2 random freezes while doing basic computer use.  Both freezes ended up with the system rebooting itself after 30 seconds, no blue screen or anything like that.  The first freeze happened when I clicked on the Weather gadget in the gadgets menu, system started lagging, then froze with a reboot after 30 seconds.  Second freeze happened while I was on Yahoo fantasy baseball page, looking at one of my teams, when I clicked the Players link, the system lagged then froze, again with a reboot.  My ambient temp things have stayed around 26-28c.  I have played a few minor games on it for a couple hours with no problems, temps still staying low.  It's just happening on minor computer usage.  Usally wouldnt have a problem with a random freeze occasionally, but twice in the 2 days Ive had the system?  Just wondering if this is common and something to expect, or does it sound like an underlying problem?  I did install Avast anti-virus when I first got the computer, no other AV on the system, and everything seems to be up-to-date as far as drivers go.  Thanks for any input. =)
