Computer freezes when playing videogames. Help :(

[rap1dcs]

So my computer recently started to freeze when i play World of Warcraft. I would be playing the game for anything between 10 minutes and several hours, and then it just dies at the same frame on the screen and all i hear is the sound lagging out, like played over and over 100 times a second. I believe there are many possible explanations to why this error occurs, but im not very good at solving issues like this one. At first i thought it was overheating, but i checked my temps in Speccy while playing and everything looks normal (kinda). CPU is around 50 degrees celcius, GPU is 60-70 degrees celcius but motherboard sometimes goes to 121 degrees celcius (obviously also an error). I should also say that it only freezes in WoW. I play CS:GO too (and Hearthstone lol) but it only freezes when playing WoW. Therefore i am asking you guys to help me! Here's my PC specs:

 

 

Operating System:

Windows 10 Home 64-bit

CPU:

Intel Core i5 4590 @ 3.30GHz 39 °C

Haswell 22nm Technology

CPU Cooler:

Arctic Cooling Alpine 11

RAM:

8,00GB Dual-Channel DDR3 @ 798MHz (10-10-10-30)

Motherboard:

ASUSTeK COMPUTER INC. B85M-G (SOCKET 1150) 28 °C

Graphics:

BenQ XL2411Z (1920x1080@144hz)

2047MB NVIDIA GeForce GTX 770 (ASUStek Computer Inc) 37 °C

Storage:

931GB Western Digital WDC WD10EZEX-08M2NA0 (SATA) 34 °C

Optical Drives:

ASUS DRW-24F1ST a

Audio:

And two case fans - one at the front and one at the rear.

 

I think the PC is about 2,5 years old, and i believe the GPU is overclocked to some degree by the store that sold the computer to me. Any help is very much appreciated!

So if you think the gpu is overclocked. Try running valley benchmark. If the pc freeze during the benchmark. Unlock voltage control in msi afterburner.

Then do a small increment to voltage like 0,15v and run it again if you pass you're good to go.
