Cannot find the root of BSODs - 0xC4, 0x93, 0x19 - prompted by gaming

This is really odd.
I have been having BSODs a lot over the last week. My PC will usually run fine for hours at a time. Then I load up Planetside 2, sometimes i go 20 minutes, sometimes 90. But, I will always crashed and get a BSOD. After that while doing less intensive tasks in windows I will get more BSODs and eventually they will stop again.
Any time i got BSODs before I sorted it out farily quickly it was AOD and Daemon Tools in the past.

I have run memtest86 on both sticks 6 - 12 passes over numerous attempts. I have checked my OS ssd numerous times with different tools (Smartmontools and Seatools).
I have run SFC /scannow multiple times along with chkdsk.
I have reseated cards.

Going through my logs driver verifier pointed at asacpi.sys as causing a crash, so i changed that to asacpi.old in the drivers folder.

I attempted to update my older drivers but having issues finding the correct versions. I updated either my Marvell or Realtek drivers (cannot remember which it was at this stage) and that caused constant BSODs no matter what I was doing so rolled back on that, went back to the usual frequency again.

When I ran driver verifier last night, I got stop codes that I have not seen regularly before, but the crash was not prompted by one of the monitored drivers, unlike in the past. So I am starting to think it may be an OS issue. But I am very reluctant to wipe my C drive, exams next week and dont want to have to set up VirtualBox and VMware software again.
I also have run numerous virus scans, and also scans with MBAM

Dumps and all of that are attached.

I just got another BSOD (D1) while playing Planetside 2 that blames a Xonar driver (according to carrona), which is the first time i have seen that.

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
