BSOD playing Dota 2, unfixable hardware error

Hi there, thanks for reading this. I was playing Dota 2 for a while, mid-game, when my game froze, there was a repetitive beeping sound, often occurs to me while watching youtube videos and playing other games, but I pass it off as some bug I'll never fix. I let the beeping continue (still frozen), when I got a BSOD with no stop code. It said I'd crashed due to a hardware error that was not fixable. I presume it's memory, my memory isn't particular expensive or reliable. If anyone could take a look at the minidump and let me know if it is memory, I'd be thankful. I've never received this error before, I still get the odd page fault in non-paged area. I think my hard drive might be dying, although I don't know how to test that.

In short, my suspicions are my memory or my hard drive. Thank you.
