Windows BSOD - IRQL_NOT_LESS_OR_EQUAL and UNEXPECTED_KERNEL_MODE_TRAP

Question

Having a bunch of issues with my pc.. i ve built this a while ago (1.5 years ago-ish). 
Recently one of my ssd failed (i had win installed on it). I couldn't install windows successfully on my second ssd because the installation process kept failing.. turns out one of the RAM sticks must ve been corrupt. After I singled out which one it was,
it all went fine..
Now my win has been running just fine for a day but I started getting BSOD's when in a game or running a video. 
Most of the time it gives the error IRQL_NOT_LESS_OR_EQUAL, and one time it gave the UNEXPECTED_KERNEL_MODE_TRAP error.
I did 3 mem tests; my 3 remaining RAM sticks seem to be fine from the memtests' perspective.
I used FurMark GPU Stress Test to see if the video card is one at fault, and got no BSOD as it was pushed to the limit.
The only other things I can think of are PSU and mainboard ?
And here are logs from the event viewer:

Answer 1

These crashes were related to memory corruption (probably caused by a driver). 
Please run these two tests to verify your memory and find which driver is causing the problem.  Please run verifier first.  You do not need to run memtest yet unless you want to.
If you are over-clocking anything reset to default before running these tests.
In other words STOP!!!  
If you do not know what this means you probably are not
1-Driver verifier (for complete directions see our wiki here)
2-Memtest. (You can read more about running memtest here)
