I attached the dump files. thanks

Has all the hallmarks of memory issue.

Please run RAM - Test with Memtest86+

this has happened not just during my gaming, but also during just like skyping someone. Its sporadic.

I'll try one sec, ive done the Windows Memory RAM test, is that not good enough?

I ran it with my two ram in the white ports, I got immediate errors. I rebooted with both in blue and I don't have any errors, is this common?
