The error appears to be related to the Numeric Processor Extension (NPX)
This looks like it could be a hardware problem but I don't know enough about this error to be sure. There is a useful procedure you can run to check that all your drivers are working OK called Driver Verifier. You could run this for a while to see if it throws up any driver errors. The details for doing it are given here. Please pay particular attention to the warnings, don't run for more than a day and before you start make a system restore point so that you can get back to a working system if you run into any problems.
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
.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)
kb will then show the corrected stack.
