Both dumps are 0x0000000A and are pointing to "memory corruption".
- A Stop 0xA message might occur after installing a faulty device driver, system service, or firmware.
- A Stop 0xA message might also be due to failing or defective hardware.
In this case your dumps are specifically pointing to hardware (memory)
I would suggest downloading a free tool called Memtest. here ... http://www.memtest.org/
Please note that it will probably work best to remove all but one stick of ram and test them individually.
This will isolate your defective module(s).
Please note also that it will require a significant amount of time to run the series of tests required to thoroughly test your ram. This is a series of 8 tests of increasing complexity, and you should let it run at least seven full passes of all eight tests (UNLESS you start getting errors).
Many people elect to let it run overnight, so they aren't just sitting around "watching paint dry".
If any errors are revealed by memtest, that module is bad.
It is not unheard of for faulty memory to pass memtest, but it is rare.
