Did you add a RAM card into your system?
Or is it the stock RAM that came with the system when new?
If you have added a RAM card, take it out in order to test for stability.
As zigzag3143 mentioned, the cash dumps point to memory corruption.
Run memtest86+ again, overnight is best.
Stop the test if you get any errors.
What is your current BIOS version?
