Hi,
the above is usually caused by an exception occurring during a routine process. What initially caused it to happen is a little vague and if you could include some more dump files that would help in tracking down the issue.
Looking over your drivers and bios though I see that some could do with updating. Your Bios is especially old and I would recommend you update this:
BiosVersion = P2.00
BiosReleaseDate = 10/15/2012
BaseBoardManufacturer = ASRock
BaseBoardProduct = 990FX Extreme4
Please ensure i have the correct page for your system board:
