PC black screen crashes during gaming

[Moorbs]

When I play games such as Black ops 3, The witcher 3, Tomb raider etc. (Sometimes Fallout 4) my PC screen goes black. The sound and programs like skype sometimes carry on but mostly It buzzes or maybe loops. I have to hard reset and sometimes when I turn the PC back on it won't post until I reset the PSU, sometimes it will post like normal and sometimes it will beep 5 times (2 spaced out but quick beeps then 3 quick beeps together).

 

Is it more likely to be a graphics card or PSU problem? Or motherboard?

I've also already tried a fresh install of windows.

 

Specs: 

PSU: Corsair CX 600W 80+ Bronze (I would buy an EVGA super nova G2 750w to replace)

CPU: Intel i5 4690K slightly overclocked to 4GHz

GPU: EVGA GTX 970 SC ACX 2.0 factory overclocked (I've tried underclocking but it still crashes about as often)

Mobo: Gigabyte Z97M-D3H

Memory: Kingston Fury White Series 8GB (2 x 4GB) DDR3-1866 Memory

Storage: Samsung 850 EVO-Series 500GB 2.5 Solid State Drive

Storage: Toshiba 2TB 7200RPM Internal Hard Drive 

 

Temps: GPU 70-80 degrees C under load

CPU 60 degrees C under load

 

I'd appreciate any suggestions.

Your PSU is low quality and not recommended for builds like that, it's probably the case here. EVGA G2 would be a good choice.

Try taking down the overclock first though

yeah, I have a feeling it's the PSU but I'd like some opinions before spending £100 on a new one (I'm pretty broke atm).

It's happened since I first built the system (before the CPU overclock). I've also tried setting the CPU and GPU to stock speeds which was just as bad.

Cause that PSU is meant only for basic system builds, not for any high-end, it was very bad ambient temperatures and it's rather for something like Athlon X4 860k + 750Ti not a GTX 970, it's just low quality. You can get a cheaper PSU if you're on a budget, any XFX PSU will do, XFX TS 550 for instance is relatively cheap and good.

Or just CX600. (Had to do that, sorry)

I had a similar problem wile using an Artic red+ 750w.

I bouught a EVGA superNOVA G2 750 ( as addviced) last week and not only is my system now stable its running better and my cpu temps are down. So my system is quieter.

 

I think its you CPU only but thats me and am no expert. I need help with most PC issues.

 

Oh and I paid £79.99 vie amazon.

I go with unstable CPU overclock.

As I said, The problem happened when my CPU was still at stock, I'm currently testing 1 stick of RAM at a time and can't get it to crash now... less heat from having an open case maybe.

Or maybe my other RAM stick is bad

update: crashed with both individual RAM stick so I've ruled that out. I guess I'll buy a new PSU and if that doesn't work replace the GPU.

So I bought the EVGA super nova G2 750w and havn't had any crashes yet. It was too big for my case though, tightest fitting PSU you'll ever see haha. I had to take my case apart to fit it in (DS cube).

It's crashed again. Wasn't the PSU. Guess I'll try sending off my GPU for an RMA now.
