Event 41 / Task 63 Random shutdown/restarts when gaming

[Ben_4_]

Been having this problem for a little while
My specs are :
Microsoft Windows 8.1 Standard 64 BIT
Intel i7 4770K - (4 x 3.5 GHZ) OVERCLOCKED UPTO 4.4 GHZ - Haswell
Corsair Vengeance 16GB PC3-12800 1600 MHz
NVIDIA GeForce GTX 770 - 2 GB - (MSI)
Gigabyte GA-Z87N-WIFI (Intel Z87)
Corsair 750W PSU (Modular) - Low Noise

I've heard alot in alot of forums on this issue that it is more than likely PSU related and others saying its other things. I'd rather have the exact problem disagnosed before sending my PSU back etc .

This is the error code i get when it happens :

My Temps CPU and GPU seem well within the manufactors limits when gaming and idle so im really not sure what to do on this one 🙁

any help would be much appreciated.

Thanks.

(Another thing i'll add is that a little while ago my PC wouldn't shutdown correctly after pressing the shutdown button on Windows it would just stay on the opening screen so i had to shutdown manually ( hold in the power button ) , this problem has seemed to go away but sometimes rare occasions happen when this persists. It might have some relation with the random restarts.)

Step 1 would be to return to stock values on everything and retest to see if it actually was an OC issue.
