Custom Built PC BSOD Randomly ntoskrnl.exe+72a40

Hello, I am currently experiencing BSOD usually while under load playing CS:GO or WildStar (crashes occur instantly or after a few hours) and I will upload the .dmp files.

-I've tried resetting CMOS as I was previously overclocked.
-I've tried running Memtest to diagnose ram (both sticks were tested separately for ~4 hours)
-I've tried reinstalling Nvidia drivers
-I've tried moving anything plugged into USB 3.0 to 2.0 ports
-I've ran sfc /scannow everything checks out
-I've run any windows updates (Including optional updates)

Any other suggestions would be very helpful.

Thanks in advance!

i have the same bsod but not while playing games, only happened once while watching youtube and browsing on firefox.
btw have you ran test on your gpu yet? and hardware temp all normal?hdd healthy?

temps have all been fine, also it's pretty new... I have only had it for about 2 weeks and for the first two weeks everything was smooth sailing. The day BSOD's started happening I don't even think I downloaded or updated anything.
