I have a Dell Inspiron 600m. It is less than a month old.  It has been working perfectly and then I came home today and it won't even turn on.   I have left at 12 and the computer was on and working perfectly. I came home at about 3 and a clicked the mouse to try and get it to wake up but it didn't. It wouldn't respond to anything so I had to turn it off.  Everytime I try to turn it on the little lights turn on but then turn off within 5 seconds or so.  It doesn't even start to boot up.  I'd be very thankful if someone could give me any help with this problem. Thanks!
