Could you upload more MiniDumps (No more than 5) at this point it seems to be Software from that 1 MiniDump but need a bit more Information.
To start with please run Prime95 on the "Large FFT's" and "Blend" Tests.
Prime95 Instructions On Use
1. Unzip and Open the program and select "Just Stress Testing".
2. Select Either "Small FFT's", "Large FFT's" or "Blend" to start 1 of the tests or Select as Indicated by me.
3. Let the test run for around 20-30 mins.
4. Remember the Results or Note them down in Notepad it only has to be this, e.g. Test: "Small FFT's" - Pass or Fail, you could just upload this Notepad File after you have run the Indicated tests.
5. Now select Options and then "Torture Test" this will bring you back to the opening menu from Num 2 above,then start following from there again, continue to do this till you have run the tests Indicated by me.
