WHEA_UNCORRECTABLE_ERROR. Tell me if its fixable or not!

So, I was having this error where I have been getting these errors for about 3 weeks. I was playing a game, but it bluescreened out of nowhere. I thought it was just a temporary problem but now every time i play a game, I CRASH! I have tried seeing if its overheating, but it isn't. When I get the blue screen, it appears for half a second, then the screen turns black, and Restarts. "Note. This goes to 0%, so I don't have minidump files :( I can't take a screenshot sadly. I am on windows 10. And Also, I think someone named DaveM121 Was helping me but he just left me in the middle of fixing it for no reason.. :( If you're here please help
