I could be gaming and it's fine but every few days I get a random game crash and the screen just freezes! The only option I have is to shut it down from the power button.

Tried clean install of graphics card drivers
I ran Memtest86, took 4 hours (checking only the cpu I think) but found no errors.
Also ran Windows Memory Diagnostic Tool and found no errors

PC is not overclocked and I don't think its overheating, temps look normal (I think)

Specs:

MSI 970
MSI Gaming M7 Z170A
I56600k
2x4gb DDR4 2400mhz
Corsair cs650m psu
Samsung Evo 250gb
Windows 7 Home Premium

Any ideas?
cheers

I'm not using any surge, it's plugged into the wall sockets.

My cpu temps are:

IDLE:
Core0 41*C
Core1 40*C
Core2 40*C
Core3 42*C

LOAD:
Core0 60*C
Core1 62*C
Core2 61*C
Core3 61*C

It just randomly crashes sometimes whether I'm playing Dayz, Battlefield or Star Citizen

Also, I was planing on getting a new power supply because I have another one of tho's 970's and wanted to try them in SLI, I'm guessing an 750 - 800 watt is sufficient?
