Freezing During Games original, now More Often.

Hey guys, new to the forum and trying to solve a really odd problem. I've got a build that has been running smoothly for a while and over the last month or two I've started getting random crashes during gaming. It will either be an audio-loop frozen screen, or sometimes a brown screen that hangs for a minute then "display driver crashed" and it kicks back in after an alt-tab. Recently it has been freezing solid in games and forcing multiple restarts.

I will drop my event viewer and crash reports here. I am honestly pretty stumped. I thought maybe:
my PSU is dying? it's older
My original SSD (I have 3...) is dying? it's older
My additional 8GB (2x4) sticks of RAM that I added in a few months ago are bad? I ran Memtest for 3 consecutive nights and had no Errors on 3-4 passes through each time.

Otherwise I am completely stumped. I updated my Intel Rapid Storage Driver from Asrock's site.

Hey no worries and thanks for replying. I have another thread going on another forum which I guess is rude to post, so I wont.

But I still am having occasional issues.. it is looking more and more like Hardware. Hilariously since updating my Soundblaster Z soundcard drivers from a driver signed 11/7/2014 to 12/14/2014 I haven't had any hard crashes in a week straight of use, but it could just be the games I'm playing.

I do occasionally get these little lag spurts that seem to be the OS stalling, which leads me to keep thinking it may be the older SSD I keep my OS on.
