Multiple Bluescreens, various reasons, mostly while gaming.

Edit: I realize I said mostly while gaming, that is not true, it ONLY happens when I play games.

I had problems with my system crashing before, which was fixed by double checking I had all my motherboard drivers installed. The problem manifested in much the same way, I could play a game for anywhere from 5 minutes to an hour, before the game would crash, followed by the computer itself. Memory Management, IRQL Not Less Than or Equal, and a few other errors that just seemed to rotate out would pop up.

It's started happening again, and it was only after we had a long power outage in our home. It's showing the same problems it did before, and I'm not sure what the cause could be. One thing I noticed is that now it seems like when they computer is about to crash, things like the sound driver stop working. I monitored my heat while playing Overwatch, which consistently crashes my computer, and it never got above 62 degrees celsius. When the game crashed, it said it crashed due to an external program, and suggested adding it to my firewall and such. This is new, I did not get an error like that previously. After clicking the more info button, I believe it mentioned something about msvcrt.

I realize it could be my hard drive, perhaps it got messed up from the power going out, but I'd like someone to at least look at these logs, if I did everything right as far that goes. I want to be absolutely sure it's a hardware issue before I get a replacement for anything.

Oh, and yes, I reinstalled the drivers that were causing the problem previously, to no effect. It didn't fix anything.
