Entire PC rebooting after some amount of gameplay

[Dropa]

Haven't had any issues with other games, but for some reason playing this the entire PC just reboots itself. Can't find any clear indicator of happened error from system logs. No blue screen or anything, just straight out restart.

Specs:
Asus ROG Strix B550-F Gaming AM4 (~4.2Ghz)
AMD Ryzen 9 5900X
Kingston FURY Renegader DDR4 3600mhz CL16 32 Gt
Asus GeForce RTX 4070 Ti ROG Strix - OC Edition
Asus ROG Strix 1000W

Imo there's some default tune (provided by motherboard) profile for CPU, but GPU is stock

Edit 1:
Originally this happened rather early in gameplay 10-20 minutes in. But it has happened in longer sessions too (e.g. 1,5 hours in game)

Before you suggest it is thermal problem, it isn't. Read the comments before suggesting it.

So far I've been able to reproduce the same problem with AIDA64 Cache & Memory benchmark where it crashes the system in the very beginning of memory copy operation. Note that other tests, such as MemTest86 do pass just fine.

check your temps while playing, might be overheating.

IIRC there would be log entry in system logs if it would be due to over heating. Will try to look into the actual temperatures next but I find it rather unlikely.

I've Noctua NH-D15 as CPU cooler and I had no issues e.g. in Hogwarts Legacy during the 83 hours of gameplay

10-20 min reboots is a sign your PC parts are slowly cooking, thats bad.

Overheating cause PC shutdown . Not a reboot. SO your right that is unlikely. I would suspect background program issues or corrupted system files or drivers.

With a 1000W PSU I highly doubted will be lack of energy even with the system full load. Unless you have RGB ♥♥♥♥ all over. Disable RGB, crack the air conditioning to 10C and launch the game..

Zero additional lights. Couple additional fans though. Definitely shouldn't be lacking power

Like the others have told you, check your temperatures first.

There might be another solution though. I have the exact same motherboard with a 5950X and had random reboots with the kernel (Linux) reporting cpu errors. Although this happened only when sculpting in Blender for some reason, never in games, it could still be a related problem. My motherboard was shipped with old firmware, version 2003 IIRC. I flashed the BIOS to version 2806 about 6 months ago and haven't had a single unexpected reboot since then. Find out which version you have. If you have the same version, or one from around the same date, it might be a clue. I don't know exactly which version this was fixed in, only know all works fine with 2806.

Since I don't know how tech-savvy you are, it's worth mentioning that flashing the BIOS is risky business and not something I would usually recommend other than as a last resort. You could end up bricking your motherboard if you're careless. If you want to try this, do it at your own risk or find someone to do it for you.

are we seriously talking about flashing the motherboard to run a video game? like i had this witty response ready. but all can think about is people think it's OK that you have to FLASH YOUR BIOS to play a game. no, that's, i can't even conceive of any reason why that's ok for a video game to release in such a state you have to FLASH YOUR BIOS.

I was talking about buggy BIOS firmware that might be causing the problem. It has nothing to do with the game itself.

My PC just did the same thing. Rebooted after 10 minutes of play. ASUS TUF Gaming X570-Plus, Ryzen 5800x and a RTX 3090Ti.

Event Viewer mentions "Computer rebooted from a bugcheck"

"The bugcheck was 0x0000003b. A dump was saved in C:\WINDOWS\Minidumps\*Random numbers*.dmp

This sounds like it's connected to the technical issues confirmed by the developers themselves. Many people including me have performance issues, where our GPU's for example go 100% at all times just by being in the game menu.

Never have I experienced any issues on any other game, on max settings. So it's most likely a CS II issue and not a PC hardware issue.

Lower the power target a bit, this game is squeezing the gpu a bit too hard. lowering the power target will stabilize your gpu without impacting the frame rate too much.

[Dropa]

Well, now that I had HWiNFO running in back trying to log the temperatures, I had no issues whatsoever during 2 hours of gameplay. The crash happened twice during the tutorial (had not yet finished sewage part) so who knows if it has something to do with it

[rustbucket80]

Also have a AMD Ryzen 9 5900X and I get the exact same crashes. Game runs fine until the hard reboot. Have seen other threads where people with same proc are having these hard reboots. Something in the game is causing this crash. Just gotta wait for patches

Hey, I have a similar problem. After 10-20 minutes the game crashes and closes itself. No PC restart. temperatures are good (CPU 55°C and GPU 67°C) System AMD Ryzen 7 3800 with Radeon RX6700XT.
