Same, no hardware issues, just with D4.
And in all of those “literally thousand” of cases they have a dying GPU or a PC without proper failsafes, Games can’t cause your PC to just randomly shut off for no reason and Diablo IV sure as heck isn’t coded with a shutdown function for your PC.
Have been having this shut down issue since the beta except i would always crash during the early church cutscene back then, now it’s completely random. Felt like it may have been a PSU issue since my 650W does not meet my 3080 minimum requirements but multiple people a posting here reporting the same issue with superior PSUs and inferior GPUs. Does not happen in any other game nor benchmarks.
Thanks for post, you put a lot of effort into explaining this issue. 
Sadly, most of the people here just don’t want to hear it, it must be Blizzard’s fault… Whatever happens, Blizzard… Card melting at 100 C? Blizzard… Card actually bricking due to fatal hardware fault, needs RMA to GPU manufacturer? Blizzard… Lag on their 1/5 bar WiFi signal? Blizzard… Stuttering and low fps? Blizzard… To the point that some n00bs get so offended that they put me in ignore, to not read hard truth and hard reality I’m telling them. 
I watch with amusement all these threads with people who don’t have a clue what is going on but first thing they say about their shutting down and overheating computer is “It must be Blizzard’s fault!!!oneone”
Haven’t heard anything of this yet and all my friends on bnet and irl have been playing just fine without their PC’s shutting down on them.
Been PC gaming since I was still in the womb and never in my life have I heard of a game shutting down your PC, especially something that requires so little of specs like Diablo.
If you’ve ever watched Tommy Boy… get yourself a new map ( I mean PC).

Could very well be your lack of wattage. The newer high end GPUS are known for their power spike issues. Nvidia recommends 750w min, gamers nexus recommends 850W+.
As for people with better PSU’s having the same issue, that doesn’t really have much baring on your situation. They could be using the single daisy chain instead of 2 dedicated cables. Using multiple cables helps the PSU absorb the power spikes easier. Their PSU brand might also be iffy. PSU’s can be quite tricky as far as quality. Take EVGA, certain PSU’s they sell are great, others not so much. So even at 1000w if it’s poor design/quality it won’t handle the spikes nearly as well as a 850w good quality one. It could also be an older PSU, so even though it’s higher wattage it wasn’t designed to handle the increasing higher GPU power spikes.
All that to say it’s most likely your PSU. You could try down clocking your GPU and lowering it’s voltage and see if that helps. You could also limit your max FPS in Nvidia control panel to whatever your monitor refresh rate is. If you haven’t turned off reflex in game try that as well. Keep in mind that all of these are bandaids for a bigger hardware issue. Your computer won’t just blackscreen shutdown/restart unless it’s a hardware issue.
If you want to stress test try using OCCT’s power stress test, that will run both your CPU and GPU at 100%. If you just stress or CPU or GPU separate you might not get the issue to occur because it might only happen when the CPU and GPU are both drawing lots of power. If you do get it to occur then stress test just your CPU using cycles and if nothing then stress just the GPU, just to rule out the CPU or GPU alone being the issue. If you don’t want to use that you can run prime95 and furmark, with furmark up tap the spacebar(iirc) every so often. This will pause the GPU test and tapping it again will restart it. The reason to do this is to try and simulate dynamic GPU loads, basically periods of almost none and suddenly lots. Static loads are easier for the PSU to deal with so you try and create the worst case scenario. Just make sure you monitor the heat since there will be lots of it. If anything gets close to 90c then cancel the test.
It might also not be power draw issues. Could be a faulty CPU(check event viewer for WHEA 18 and 19 errors), faulty PSU, faulty memory, Power cables not plugged in fully, GPU not seated fully, BIOS issue, or Temps(CPU/GPU/VRM/Mem). SUPER fun to diagnose /s.
My best guess is that D4 being so unoptimized is causing both peoples CPU and GPU to be stressed to their max, sometimes at the same time and thus people are finding out they actually have hardware issues. Most games aren’t incredibly un-optimized on both CPU and GPU so the issues might not show up. We know opening up the inventory/menus as well as cutscenes cause massive GPU/CPU spikes.
I also just want to say, this issue is not just a D4 issue. There are just millions playing it so you’ll see more reports of issues. The whole blackscreen restart/shutdowns are something that has happened in tons and tons of games. Some games hit the right spot on bad hardware and the system goes down. The cause is almost always hardware and some “fixes” just compensate for the hardware issue.
Yes many people are having issues, with hardware scaled up n down the line up’s of SKU’s for GPU’s. ALL of which are pretty random.
yes some gigabyte faulty cards here n there. Nothing new.
The only card I have played this game on that has not crashed, repeatedly.
Like black screen total shutdown computer crash, without an error report or a windows reliability crash report/vice versa was on a 980ti.
I have seen 1080’s, 1080ti’s, 2080ti, 3070,3070ti, 3080,3080ti,4090,4070 and even a few AMD cards in the 6000 series have definitely been crashing according to friends and personal experiences.
This game is the only game that my 2080ti is crashing with.
Fresh drivers and chipset drivers have been applied after DDU, Every other game, including benchmarks which if you have a faulty card or piece of hardware. ANY benchmark software is designed to let you know that.
This game has a serious issue somewhere and its absolutely destroying people’s cards.
I fixed the issue previously for about 4 days by uninstalling the texture pack, Now after the latest hotfix/patch. The game is doing it again, without failure.

Unfortunately comments like this are better left unsaid, This adds no actual layer of education and if your game wasn’t crashing. Why would you be here? Total waste of space/time on this comment. Thanks for posting your hardware for the class too see.

probably because people play other games besides blizzard products that are more demanding. If a PC can run Elden Ring without an issue, then it can run this game too. The point is. If your computer is running flawlessly in everything else, including benchmarks provided BY BLIZZARD. You provide THEM with the .xml logs etc for them to help troubleshoot their games and they STILL simply haven’t fixed BASIC stuff they claimed they’ll look into, according to the launchers details.
Its just a joke, this game should not and I repeat with flying rainbow GAY colors. SHOULD NOT BE BRICKING or even remotely CRASHING peoples hardware. AT ALL.
This topic should not even be coming up.

Blizz should make in-game benchmark. Or demo version of the game.
So everyone could see their staple performance to compare to, and see if they are crashing on anything during said benchmark.

Same thing here since the last hotfix. Everything went fine, but now my PC crash after only a few minutes in game.
I did the whole battery of tests, ram cpu GPU power supply, everything is ok, and everything is ok on other games. (3080 stock, 32gb ram, 9900K)

Hello all. I also think, that most users that have the problem with their computer, shutting down and rebooting when playing this wonderful game, have some serious hardware issues. Often users are unexperienced and make mistakes with their hardware. This starts with building the computer, not really knowing, what they are doing, then undervolting and many more mistakes…. and just because the computers can handle other games, it doesn’t mean, that this game is causing your problems. Don’t blame blizzard. They made a really good game and it’s well optimized. I have 3 computers, all are running Diablo 4 without issues. My oldest computers hardware is a i7 2600K with 16 Gb RAM and a GeForce gtx 1080 on a Corsair AX 850 Watt.
We could also say, that it’s a Layer 8 Problem. Sorry but in most cases this is the real reason.
To me, the error started today. I open the game, and after a while, my PC restarts. I’ve been playing for several days without any issues, and now this error has started. It’s not a problem with my hardware since I’m a regular VR gamer, which means it pushes the computer to its maximum without any problems. I have a Ryzen 7 5800X and a 3070Ti, and I’ve never had any problems, neither in VR nor in the most demanding games. This is clearly an error on their part, they have programmed something incorrectly that causes some kind of infinite loop, which results in the PC crashing. It’s not a user problem.

As some others have pointed out this is likely a combination of hardware and software (D4) causing the issue.
TLDR - I fixed my sudden power offs\restarts by upgrading my Corsair SF750 to the new Corsair SF1000.
My issue started on Sunday night.
I have been playing since early access and did not have any issues with restarts\hangs until Sunday. I was doing a Helltide when my system suddenly shutdown and restarted. Prior to this I had may long gaming sessions without an issues.
PC Specs:
Windows 11 Version 22H2 (OS Build 22621.1848)
- Intel - 12900k - OC = P-Cores - 5.3Ghz on 3 cores and 5.0 on the rest. E Cores - 4.0Ghz (all)
- Asus - Prime z690M-PLUS D4 Mainboard (Latest BIOS 2404)
- Corsair Vengeance RGB Pro 64GB (XMP I Enabled)
- WD_BLACK SN850 NVMe SSD - (Gaming Mode enabled)
- GeForce RTX-3090 - OC = 200Mhz Core and 500Mhz Mem
Case: - (Included to show the level of cooling)
- Lian-Li 011 Dynamic Mini
- EK-Quantum Reflection PC-O11D Distroplate (Custom loop)
- EK-CoolStream SE 360 x2 Radiators
- 7x Lian Li 120mm fans and 2x 140mm fans filling all available cooling spots.
With this cooling setup and can run the D5 Pump at 40% RPM and the fans at min speed when not gaming or rendering video and see CPU temps of 30c on the hottest cores and 22c (room temp) on the coldest.
The CPU under load (Cinebench) for a single test and no changes to RPM on the pump sees the highest core hitting 81c and the lowest at 73c.
Yesterday the restarts while playing D4 got worse. It was to the point that just starting the game would restart my PC.
I attempted to reproduce the issue using other games and benchmarking tools and was not able to get the system to fail. This has to be an issue in the D4 code.
I was monitoring the temps of the system using HWMonitor and while I was seeing some higher than normal CPU temps on some of the P Cores (Example 87c). This had me thinking it might be a thermal issue that was showing up after the coolant was heat soaked, so I increased the fan speed on the rad fans and also increased the RPM on the D5 pump. The temps were better and I thought I had solved it! Nope the system was still restarting and was in fact getting worse.
Having read about the new SF1000 PSU and knowing was pushing the limits I decided to pick up the new PSU and give that a go.
15 hours of gameplay with the new PSU and no restarts. Yay!!!
I still think there is something in D4 that is hanging\looping a CPU process because with the new PSU and no other changes to the cooling (40% RPM Pump, Min on the Fan) I have seen temps on a couple of the P Cores hit 100c. I now have the fans set to 80% and the D5 Pump set to 100% when playing and the temps are better, but still higher than what I would expect.
Thanks to anyone that reads all of this, I do hope it helps someone that is having similar issues. More importantly the Dev team needs to dig into this issue. I can tell you as someone that has been testing software\hardware for 20 plus years there is something in the code that is contributing to this issue.

Not sure if problem has been fixed but I saw OP saying he’s using a mini PC. Anything shutdown related is due to overheat or PSU not able to handle the power needed by the PC. Small PCs usually have less powerful PSUs and D4 is pretty hard on hardware so if you have old and/or cheap hardware, D4 will push it to the limit. Game definitely need optimization and better coding tho.

Okay I may have fixed this for myself. I’ve been playing for two days now, several hours at a time, and my PC hasn’t shut down once. Here’s what I did:
I have a 3090. I took it out and noticed there is a small physical switch on one side that I’d never seen before. It had two settings: Quiet Mode and Performance. It was on Quiet Mode. I switched it to Performance. I’ve never seen such a switch on a graphics card before. I’ve noticed since flipping it that the Nvidia overlay shows my GPU staying at 65 instead of 70 degrees.
I unplugged and reseated all my RAM.
I put little heat spreader things on my hard drives because they didn’t have them before.
I feel like that switch on the graphics card was the most suspect.
Interesting. I have heard of it, but wasn’t aware they were using them still.
Hello there!
Been having similar issues the past week, never had an issue until probably launch day when it crashed and rebooted,
I thought it was one hardware component so I upgraded, had no issues for a few days then have returned to the issue again.
Any thoughts? Has anyone experienced the issue with the new Nvidia driver?
Thanks 
Specs:
CPU: i9-9900KF
GPU: RTX 2070 Super
RAM: 32GB DDR4 3200Mhz
Storage (Game is stored on here, had first issue on SSD): NVMe
650W PSU
Not having issues with temps or load on anything but the GPU’s VRAM it seems and plenty of other games function perfectly fine
Edit: Graphic settings are also as low as they can be or the ‘low’ standard in D4
this issue seems mostly to be a VRAM related issue but there have been other issues with this game so if you are having a similar problem but technically not this issue these fixes probably wont work (such as the NVMe crashes etc.). for me with a 3070 on 1440p I was getting crashes every 20-30mins, after changing textures to medium, nothing for hours.
@cheshire The switch on your GPU to change the BIOS to Performance will increase the fan curve to run more aggressively cooling down the VRAM. Most GPUs don’t take into account the VRAM cooling requirement for their fans so if the VRAM is running hot the GPU doesn’t usually change the fan speed to accommodate.
It seems most fixes are other ways to reduce the load on your VRAM, reducing the resolution of the game, reducing texture quality etc all does this.

Yep. I have been noting this and trying to raise awareness to it for nearly a week now since I first encountered it.
It was because of that I setup a custom fan curve for my 3070Ti. Now the memory stays at a safer temperature, even if its still the hottest thing on the card.
