Just had a look through your dumps TBH i had a prob that most of them wouldnt load properly, not sure why!
From the ones that did load there is a variety of error codes mostly 0x8E & 0xD1, a lot of them stated memory corruption but i think it may well be driver induced
A good place to start would be memcheck86 to test your ram, follow this link download, burn to disk boot from disk and run for multiple passes (recommend min 5 passes or overnight) to check your ram Memory Diagnostics
Some other dumps indicated the driver Ph3xIB32.sys causing the crash, this driver file seems to be associated with a Phillips PCI TV tuner card (i think) if you have something like this on your system then i recommend visiting their website for a driver update
You also have two old drivers on your system i recommend these are updated or removed
Hope this helps
