Blue Screen On Brand New Windows 7 PC | Bug Check 0x7F

I have a 100% brand new hardware and it has been 100% stable for the past 3 months. Today I got my first blue screen and checked the windows log to find this:

The computer has rebooted from a bugcheck.  The bugcheck was: 0x0000007f (0x0000000000000008, 0x0000000080050033, 0x00000000000006f8, 0xfffff800031058c1).

A dump was saved in: C:\Windows\MEMORY.DMP.

Report Id:  Bug Check 0x7F: UNEXPECTED_KERNEL_MODE_TRAP

0x00000008 , or Double Fault , indicates that an exception occurs during a call to the handler for a prior exception. Typically, the two exceptions are handled serially. However, there are several exceptions that cannot be handled serially, and in this situation the processor signals a double fault. There are two common causes of a double fault:

  • A kernel stack overflow. This overflow occurs when a guard page is hit, and the kernel tries to push a trap frame. Because there is no stack left, a stack overflow results, causing the double fault.
  • A hardware problem.

It may caused by ZoneAlarm, if you have it installed, update the network card drivers first.

You can also try this Hotfix if updating the network driver doesn't fix it:
Stop error message when you run an application that transfers data by using the UDP protocol in Windows Server 2008 R2 or in Windows 7: "STOP 0x0000007F"

When this doesn't fix it, remove ZoneAlarm if you have it installed.  If you still experience problems with it, Please configure your Windows to create a kernel dump and upload the zipped dump (C:\Windows\memory.dmp) here or any of your online file sharing account like SkyDrive and post a link to haja @ bench . com.
