BSOD playing games like H1Z1 and watching Twitch.tv

Hello, this is my first post, and I created this account today because I have been having a frustratingly enormous amount of BSODing happening to my computer lately. This has been going on for a period of about a couple weeks now, with an increasing frequency as time goes on. The problem is that I cannot figure out exactly what causes them because I get different error messages almost every time when my computer BSODs.

Here's a list of them with how common they reoccur for each time I get a BSOD:
1. KMODE_EXCEPTION_NOT_HANDLED - (very common)
2. PAGE_FAULT_IN_NONPAGED_AREA (Npfs.SYS), also (dxgkrnl.sys) - (very common)
3. IRQL_NOT_LESS_OR_EQUAL - (not as common)
4. DRIVER_IRQL_NOT_LESS_OR_EQUAL (Wdf01000.sys) - (not as common)
5. SYSTEM_SERVICE_EXCEPTION (win32kfull.sys) - (not very common)
6. BAD_POOL_CALLER - (only happened once)
7. APC_INDEX_MISMATCH - (only happened once)

I have pinpointed the triggers of these BSODs to activities such as:
1. Playing games, particularly multiplayer, like: CS:GO, H1Z1, The Culling. When this happens, either my computer will BSOD directly from my game, or my game will crash me to my desktop, and then my PC eventually BSODs if I persist to play the games.
2. Watching Twitch.tv. When this happens, Google Chrome will display the "aw snap" page and all of my pages in Chrome will crash, but not Chrome itself, and then I will almost always immediately get a BSOD after a few seconds of that screen appearing.
-I can play games like Darkest Dungeon which is offline and not very graphics intensive, and I will never get a BSOD.

I have tried to browse around and try everything that comes up from other forum websites, posts, and even articles on the topic. What I have seen when I google each error message is that people are using /sfc scannow and /dism /repairhealth to remove corruption.

Things I have tried which failed fixing the problem in order:
1. I uninstalled, reinstalled, and updated my Nvidia GTX 770 drivers because a lot of my searches correlated with people mentioning that these errors can come from a problem in your graphics drivers. I thought this made sense too because my BSODs get triggered by multiplayer games and twitch.tv, however this failed.
2. I tried removing write caching on my disk drive because it was mentioned in another form post as a possible solution, but nothing changed.
3. Upgrading from Windows 8.1 to Windows 10 to see if it would give me uncorrupted, updated files. (I eventually downgraded back to Windows 8.1 after this failed)
4. Using /sfc scannow. The first time I used this, I got the message that says corruption is found but not everything was able to be fixed. So then I proceeded to use DISM /restorehealth which "successfully removed corruption", however a few days later I still got BSODs. I thought this was odd because this was the solution on nearly every post I read, so I went back to scan using /sfc scannow once more, and this time it said no corruption is found (what?!?!), but I still get BSODs.
5. I went into my Device Manager and literally right-clicked and searched for updates on every single driver, but I still get crashes and BSODs.

I now am clueless due to the error always changing, and I ran out of ideas for what I can possibly do after Googling for hours and trying everything I saw.

My PC Specs:
Graphics Card: NVIDIA GeForce GTX 770
Processor: AMD FX(tm)-6350 Six-Core Processor - 4.23 GHz
Installed Memory (RAM): 16.0 GB
System type: 64-bit Operating System, x64-based processor
OS: Windows 8.1 64-bit

Sorry for the long post, and thank you for your time!

Please update your BIOS and test your memory.

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums

Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

Diagnostic Test

   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

So what do I do if errors do pop up. I don't know how to keep a log of them, and I don't know what to do about them.... I already did one run, and it stopped working after a certain percentage, but before it did it found 12 errors. Yet again, I don't know how to keep a log of that or fix them.

That is explained in the tutorial and I have also explained that in the 'addition' part.
