Pantallazo azul a veces

Hola:

He encontrado un de esos raros problemas que a veces producen los pc´s, Os
comento, resulta que tengo instaado el autocad, el cual es el programa que se
ultiliza más habitualmente. El equipo no tiene mucho tiempo desde del último
formateo. El problema viene cuando al ultilizar la herramienta círculo del
autocad se me reinicia el ordenador sin motivo aparente, a veces me indica un
panatallazo azul, por eso he ultilazo el programa windbg y he analizado el
archivo dump que me genera el error y me da este resultado:

UNEXPECTED_KERNEL_MODE_TRAP (7f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault). The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
use .trap on that value
Else
.trap on the appropriate frame will show where the trap was taken
(on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.
Arguments:
Arg1: 00000008, EXCEPTION_DOUBLE_FAULT
Arg2: 80042000
Arg3: 00000000
Arg4: 00000000

Me indica que le problema viene con el archivo ntoskrnl.exe, pero no se
exactamente para que sirve he mirado por internet pero no consigo saber
claramente lo que es y lo más importante como resolver el problema, ademas de
saber que tiene que ver con la herrramienta circulo del autocad...Espero que
podais ayudar.

Un saludo para tod@s.
