Background information on Stop Error message
http://msdn2.microsoft.com/en-us/library/ms795478.aspx

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. If you think
this overview has occurred, use the !thread debugger extension to
determine the stack limits, and then use the kb (Display Stack
Backtrace) debugger command with a large parameter (for example, kb 100)
to display the full stack.
A hardware problem.


0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP
One of three types of problems occurred in kernel-mode: (1) Hardware
failures. (2) Software problems. (3) A bound trap (i.e., a condition
that the kernel is not allowed to have or intercept). Hardware failures
are the most common cause (many dozen KB articles exist for this error
referencing specific hardware failures) and, of these, memory hardware
failures are the most common.

Are there any yellow question marks in Device Manager? Right click on
the My Computer icon on your Desktop and select Properties,
Hardware,Device Manager. If yes what is the Device Error code?

Try Start, Run, type "sigverif.exe" without quotes and hit OK. What
drivers are listed as unsigned? Disregard those which are not checked.
