Repeated Crashing of Computer

HI,
My computer is a Dell Studio XPS 16 laptop. It has been crashing and giving BSOD many times a week. So, I reverted back to the factory default image. However, it is crashing again. Though it has not shown a BSOD, it freezes and has to be powered off. When booting, even before I login, it automatically restarts itself. This is very frustrating and I need your assistance. This happend today morning 06/09/2011 between 9-10:00 AM. I am uploading the event viewer logs and a snapshot of the event. Do let me know if you need any additional information.

Basic System Spec
- x86 (64-bit)
- Windows 7 Home Premium 64 bit
- OEM Version
- Age of hardware = 1 Year
- Age of OS installation - 3 days (reverted back to factory settings due to repeated crashes)

I wouldn't mess with any more tests. Let Dell know what you did and the # of errors it came up with and hopefully they will replace it.
