Random BSOD Error BcCode 124

I need help interpreting this BCCODE. I am encountering a random crash during computer use. I can not seem to correlate this with a specific action or process, i.e. it happens at different times doing different things. Below I am including three of the BSOD error messages. I have tried changing out RAM and have made sure that my temperatures are good in the case. I ran memtest for 4 hours with no errors, also prime95 did not produce and crash. Any help would be greatly appreciated.

My system:
AMD FX 8120 Eight core 3.1 ghz
Sector 5 DDR3 1333 mhz RAM (4x4gb)
2 Geforce GTX 550 TI SLI
Gigabyte 990fxa-ud3
Windows 7 Home Premium 64x
