PC Freezes/Locks Up

[pmainwaring]

Hello all.

So...I went ahead and build my own PC!

 

Oh boy...

CPU Cooler: Corsair CW-9060025-WW Hydro Series H100i
Motherboard: Asus Z170-A ATX LGA1151 Motherboard 
Memory: Kingston FURY 16GB (2 x 8GB) DDR4-2666 Memory
Storage: Crucial BX100 250GB 2.5" Solid State Drive 
Storage: Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive 
Video Card: MSI GeForce GTX 970 4GB Twin Frozr V Video Card 
Case: Fractal Design Define R5 (Black) ATX Mid Tower Case 
Power Supply: XFX XTR 650W 80+ Gold Certified Fully-Modular ATX Power Supply 
Operating System: Microsoft Windows 10 Pro OEM 64-bit 
Wireless Network Adapter: TP-Link TL-WDN4800 PCI-Express x1 802.11a/b/g/n Wi-Fi Adapter 
Monitor: BenQ GW2765HT 27.0" 2560x1440 60Hz Monitor 

 

Everything works great...apart from this one little major problem.

 

When using the PC for Gaming (Firewatch, Oxenfree, Team fortress, Cities: Skyline) or Editing and Motion Graphics work (Premier, After Effects, Cinema 4D) after a while, the PC will just lock up. The sound will cut, the screen will freeze like a screenshot. The keyboard doesn't respond when I hit CapsLock (as in, the light doesn't come on). The fans still spin and the light on the case is still on, but it is not responding. It needs a hard reset to get it back.

 

Now, this freeze, or lock, can happen after 10 minutes, 20,30,50 minutes. A hour or two. But it will happen.

And once I reboot, there's usually a 90% chance it will freeze within the first 5 minutes of logging in.

 

I have ran the Valley GPU stress test and found that sometime it would run for 10+ hours with no problems, and sometime it would crash in under 10 minutes.

Basic use if fine. Web browsing, Netflixing, Spotify-ing and so on. 

 

I've reinstalled Windows 10 a couple of times...I've also managed to get a working hackintosh on this thing and it STILL had the same problem. The whole "install this old driver, run this, run that, do that" done it ALL with no help. 

 

I checked the temps off CPU and GPU and they're fine. GPU is about 70C and the CPU is about 50C. 

 

I've taken everything out and put everything back in.

 

After each freeze there's no crash dump, no logs (apart from the one informing that the PC was shut down incorrectly due to me holding the button down

 

I'm not sure what else I can do tbh.

 

I need some proper advice.

 

Any helpers?

 

Cheers

Are you running overclocked? Also, please don't highlight your text in white. It really defeats the purpose of using night mode

 

[pmainwaring]

I am not overclocking anything. Everything is vanilla.

 

And, whats highlighted white? I haven't highlighted anything white...

Run a stress test

Don't worry about it then. It's probably a bug or something.

[pmainwaring]

I have ran stress tests.

 

About 4/5 different ones.

 

Prime, everything was OK. CPU stress tests, they were fine. GPU stress tests as mentioned does sometimes crash, but only the Valley one.

 

Rendering out of AE, Crashes. Playing games, Crashes. 

 

I've had it on for 20 days in a row, no crash. Boot up a game and playing for a while Crash.

First of all, don't use Prime95. It puts stress on your cpu to a point where it can wreck your CPU. In other words, it works too well.

 

Second of all, what are your temps?

[pmainwaring]

As mentioned in the first post. GPU will Max out at about 70/72C and CPU idle is about 20C and there goes as high as maybe, 58C I think.

Do you have another CPU you can try?

[pmainwaring]

I do not no...

Ram?

[pmainwaring]

I have no 'handy' hardware to hand. I kinda bought what I needed to build this machine. 

[pmainwaring]

CPU tests as fine. 

Done RAM tests and they're fine. Swapped them around. Used one stick only. All combinations of RAM slots have been used, all crashed while playing video games or rendering. Although, playing video games is the one I can get it to crash on the quickest. Even if it's something small like Oxenfree.

[Aaronius_Leonius]

Maybe try with your integrated graphics. It might be a video card problem

[pmainwaring]

Borrowed the same GPU from my friend, the PC locked up after gaming.

 

Any other hints?

[pmainwaring]

Like...seriously? No one can answer my question? really?
