Computer restarting without warning during Rust gameplay - Rust

Hello, I have an issue that's been going on for quite a while now. Before anything I want to point out that [U]this issue occurs only during rust gameplay[/U]. So the issue is just as the description states, my computer restarts without any warning or error messages before, or after the crash. The weird thing is that the crashes are not consistent at all, because sometimes it runs hours without crashing, sometimes it crashes every 5 minutes of gameplay. I have been looking for ways to fix this but I cannot seem to find an easy solution. I have tried monitoring my temperatures in case it's overheating, but my CPU never goes above 70°C and my GPU never goes above 60°C, so that's not the issue. Like I said, this only happens on Rust and not in any other game. I can leave the PC running for days playing other games and it doesn't crash once. So this makes me think it's not an issue from my side, but I can't be certain. If anyone has any experience on knowledge, I would greatly appreciate any help I can get. In case anyone has any questions or info from me in order to help me out, I will gladly answer them. Thanks, Martin

Could you post your specs including psu?

[QUOTE=zenthekiller;50549672]Could you post your specs including psu?[/QUOTE] Yes, no problem. - Intel i7-4790K (with aftermarket cooler) - Nvidia GeForce GTX 970 - 8GB DDR3 RAM - 750W PSU CoolerMaster Gold - MB Z97D3H I bought this setup exactly a year ago and played rust ever since. The issues only occured 2/3 months ago. Also I'm running Windows 10 as of yesterday, previously had windows 8.1 issue stays the same.

Keep an eye on the temps of your system, sounds like a thermal issue. A defetive PSU is also not unlikely.

run a complete memtest on boot. This is a problem with your pc, not rust.

Get [URL="http://www.nirsoft.net/utils/blue_screen_view.html"]BlueScreenView[/URL] and see if the restarts are generating BSOD crash logs. If so, they should have info that can help us. I'd also preemptively make sure your Nvidia drivers and sound drivers are up to date.

As for the defective PSU I cannot be certain but it doesn't make sense, since I have no issues running other high-end games.

And I double-checked the drivers, all up to date.

This [URL="http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html"]PSU tier list[/URL] ranks your PSU as Tier 3 which isn't bad but isn't great for high-end/intensive use. Rust is still not optimized so it will put more drain. The issue could also be your ram which is on the minimum 8 but will still give you less performance. Have you tried fps.limit 60 in the console or lowering graphics quality?

Also, I've ran Rust for months with the same setup and same RAM, didn't make issues. Don't see why it would start now. And I'm not running high/max graphics, rather low.

this happened to me once and it was a damaged ram chip, and yes it started without notice, out of nowhere. Google how to run a memtest if youre not sure. [QUOTE=tejota;50549787]run a complete memtest on boot..[/QUOTE] edit: also to check if its your PSU, start by looking at your voltages on the BIOS. Check Google for the right expected values and check if they match edit2, check this out: [url]https://m.youtube.com/watch?v=69QPICpagoc[/url] keep in mind these values could be meaningless if the sensors are off, but it's a start

It taxes your system really hard. :) If your system does not restart while it runs, your PSU will most likely be fine.

80° on the cpu is a bit high lol. Dilla is on the right path. Check your hardware

[QUOTE=raz r23;50550435]80° on the cpu is a bit high lol. Dilla is on the right path. Check your hardware[/QUOTE] I never stated anywhere it reaches 80°C... I said it never even reaches 70°C. SMALL UPDATE: Yesterday I did fps.limit 71 and ever since then my PC hasn't crashed after hours of gameplay on Rust. It's super weird if this did the trick but something happened, I'll play some more and see if it crashes again.

I guess your system isn't overclocked?

[QUOTE=dilla;50554082]I guess your system isn't overclocked?[/QUOTE] No, neither GPU nor CPU.

[QUOTE=Martos;50554164]No, neither GPU nor CPU.[/QUOTE] Then, it really could (!) be the PSU. You'll have to see if you're happy with ~70fps or not. But to be entirely sure if it's a issue caused by rust or a hardware component, you should give RealBench a try.

A 750w psu isn't enough nowadays? :pudge: I got a Leadex 80 Plus Gold 650w psu and don't have any problems in new games, only rust makes problems if I run it in normal (dx11) instead of dx9.

UPDATE: - To the small update I submitted yesterday saying it might have been fixed, it's not. My PC crashed again, however I was able to get 5-6 hours of straight gameplay without a single crash. - I ran RealBench, both a benchmark and stress test. The stress test ran for 30 minutes, whilst I was using the PC to download programs to monitor the temperatures.[URL="http://prntscr.com/bj0on5"]http://prntscr.com/bj0on5[/URL] the image is after the stress test/benchmark, and the system ran perfectly without any issues. - Also to @elixwhitetail, I downloaded the program but even after the crash there was no report shown. - On a sidenote, even though I have 8GB of RAM, during rust gameplay I noticed the RAM usage went up to 98%. Could this be an issue?

Really sounds like power issues to me. Limiting the FPS probably keeps consumption (mostly) under whatever threshold is causing your PSU to run out of spec. It might for example be able to output 500W without the voltage dropping below whatever level your motherboard considers acceptable, but 550W is too much for it, the motherboards protection (perhaps momentarily) cuts power and your system restarts/shuts down. You won't get a blue screen from this, it's more like hitting the reset button on the front of the PC. It's also possible that the PSU itself is intervening and preventing itself from supplying too low (or high) voltage. It's quite likely that Rust is the most stressful game that you run, not necessarily because it's the most beautiful, it's just the one that currently uses (wastes) the most CPU/GPU resources. What you're describing cannot be caused by software alone, it's a hardware failure of some kind, and it looks like you've basically ruled out thermal issues. That leaves power.

[QUOTE=Martos;50559864]UPDATE: [...] during rust gameplay I noticed the RAM usage went up to 98%. Could this be an issue?[/QUOTE] A bold [B]yes[/B]! :) Just before starting Rust, you should have a RAM usage of 1,5GB at best. My gf also has frequent crashes, if she doesn't free enough RAM before playing.
