Windows 7: Machine_check_exception (9c)

I turned on my computer this morning. Opened a pdf I had created the night before, opened a firefox window. Then my mouse stopped moving. Within a couple seconds this changed to a BSoD.
I have an HP e9150t with an i7-950

1 - Bugcheck Type
1 - MCA_ASSERT
2 - MCA_GET_STATEINFO
SAL returned an error for SAL_GET_STATEINFO while processing MCA.
3 - MCA_CLEAR_STATEINFO
SAL returned an error for SAL_CLEAR_STATEINFO while processing MCA.
4 - MCA_FATAL
FW reported a fatal MCA.
