Windows 8.1 various BSODs (Faulty RAM?)

Hello,
For the past few days I've been experiencing bad BSOD crashes on my PC.
My specs are as follows:

i5 3570k
16GB Corsair DDR3 Vengance LP (2x8GB)
Asrock Extreme4 z77
Samsung 840 Evo SSD

The BSODs have given various error codes (I've attached the minidumps from the last 4). I think they're all related to system memory.

When my PC first boots up everything works fine, it seems to run smoothly. But over time it becomes unable to load webpages (Firefox and Chrome both crash and cannot load google,youtube etc) and then things such as my antivirus service (Bitdefender) force closes and performance becomes quite slow.

I built the PC in 2014 so the RAM is 4 years old so it would not surprise me if this was the issue. I ran Windows Memory Diagnostic for two passes and it didn't find any errors, and a month or so ago I ran Memtest for one pass and that didn't find any issues either.

I think the next step would be to remove one of the sticks of RAM and see if I still get BSOD/Slowdown issues.
I installed WhoCrashed and these are the BSODs:

1) This was probably caused by the following module: hardware.sys (hardware)
Bugcheck code: 0x3B (0xC0000005, 0xFFFFF803195F394F, 0xFFFFD000367686A0, 0x0)
Error: SYSTEM_SERVICE_EXCEPTION


2) crash dump file: C:\Windows\Minidump\073018-14109-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x1554A0)
Bugcheck code: 0xF7 (0xFFFFD00036604CC8, 0x1E882CDD77CA, 0xFFFFE177D3228835, 0x0)
Error: DRIVER_OVERRAN_STACK_BUFFER

3) This was probably caused by the following module: ntoskrnl.exe (nt+0x1554A0)
Bugcheck code: 0x1E (0xFFFFFFFFC0000005, 0x0, 0x8, 0x0)
Error: KMODE_EXCEPTION_NOT_HANDLED

4) This was probably caused by the following module: ntoskrnl.exe (nt+0x1554A0)
Bugcheck code: 0x1A (0x41287, 0xC1266221D4, 0x0, 0x0)
Error: MEMORY_MANAGEMENT

I've linked below the .dmp files, I would greatly appreciate any help that anybody could offer me.

Thanks!

looks like you had Malwarebytes trying to read virtual memory then it hit a exception and the stack was corrupted and data rather than code was run and the system bugchecked.

I would remove
zamguard64.sys Wed Aug 17 10:06:53 2016
Zemana ZAM AntiMalware driver

also remove
SUPERAntiSpyware from 2011

most likely these two drivers are messing up the Malwarebytes scan
