Pc restart.

[Heartbre4ker]

So i just started playing the game and each time i load my save my pc reboots, my pc is brand new so it's impossible that the psu is faulty. espically that i played starfield a much more demanding game for hours and nothing happened
can anyone help

pc specs:
gpu: rtx 3080ti
cpu: I7-13700k
psu: msi MAG 850W

next gen?

have you tried to load a new game save? does it work?

have you tried no steam no red launcher?

you sure you deleted all old mods that are not for next gen? (do unistall on steam , delete files manually and including in documents witcher 3 , try new game , load a save , does it work?)

have you used script merger?

newest gpu driver?
windows update?
read only files?

check event viewer

thanks i've fixed it by starting the game in dx11 instead of dx12

DX11/DX12 doesnt make a PC restart without a BSOD. It doesnt work that way.

Its most def a hardware issue (BIOS, OC, faulty hardware, etc.). A PC doesnt restart out of the blue. And it also doesnt matter if other games wont recreate that issue since each game has a different GPU/CPU load.

You have to test each component individually to get to the bottom of this issue, starting with your RAM (XMP, OC, etc.) everything back to stock and using tools like memtest64, Cinebench, etc.

edit:
If we had a BSOD, I could throw look into the log file and tell you your exact issue but a cold restart without any log file.....Could be PSU, RAM, GPU,CPU, you call it.

Even if its runs well for now, it will prob happen again.

A cold restart is a textbook example of the OCP (Over Current Protection) tripping in your power supply. 3080s and 3090s have a known problem with spiky current draw with peaks over 2 times the rated power draw which can cause the some power supplies to trip the OCP. In fact it happens on a lot of good power supplies because their protection works faster where the cheaper ones are slow to react and are set to trip at too high of current.

Part of your problem is the 12V output is shared with a 13th Gen Intel CPU that aren't exactly known for their power efficiency so the bare minimum rating for the power supply by the GPU manufacturer may not be enough because of the extra that is being drawn by the CPU which is going to share one of the two 12V rails in your power supply with the GPU. My educated guess is both the CPU and GPU are drawing a lot of power when the game starts and drawing in excess of 450W on one rail tripping the OCP (Each rail can only handle 1/2 the rated output)

Sadly the only solution is a larger power supply but you could try turning off the E cores which should lower the CPU current draw. This game still doesn't thread correctly in DX12 so it probably wasn't really using them anyway so you probably won't notice any difference in performance.

it is actually from the game not a hardware problem, i've sent my pc for maintenance and they found nothing, if you google (witcher 3 pc reboot) you will find its a common problem, thank you

thanks

I helped a guy a couple of years ago who had a 3080 and a 850 W platinum from Seasonic, one of the highest rated power supplies. In his case the game that was causing him problems was AC Origins while he had no problem with AC Odyssey or AC Valhalla which are more demanding. His problem is he had 5 12V outputs and he had the mother on one rail with two 12V outputs and the GPU on the other rail with three 12V outputs. What I had him do to fix the problem was remove the extra going to the motherboard (4 pins on the MB end) since it wasn't actually needed and was just a gimmick and put one of the GPU lines to that connector which balanced the GPU load across both rails.

It completely fixed his problem .... Just for the record I'm an electronics engineer (30+ years) , have been working with the x86 platform since 1988 and also worked for 5 years at a PC manufacturer in the late 80's and early 90's

I suggest watching this video from Gamers Nexus for further details into the the 3080/3090 current spike problems and how they can randomly trip a power supply OCP
https://www.youtube.com/watch?v=wnRyyCsuHFQ

Note also that this video was made before the 40 series came out and speculates that it may have an even worse problem Nvidia was able to fix the current spike problem in the 40 series. It probably had a lot to do with the Samsung 8 nm node which wasn't very power efficient to begin with compared to the TSMC 4 nm node that the 40 series uses. However that doesn't change the reality of the 30 series current spike problems with the 3080 and 3090

I had exactly the same problem today, until now everything was fine

try playing it in dx11 instead of 12, worked for me

Its everything but impossible.

Again, this is not how PCs or programming interface work. It wont, and I repeat, WONT, make your PC restart without any bluescreen log, whatsoever.

You can deny it all you want, ask ANYBODY on a legit hardware-board and they will tell you the exact same thing.
There is something wrong with your hardware. It is what it is.

Its not because the maintenance guy's of your pc shop say's that it was fine, that you are fine. Trust me i went also to my local pc shop with a issue, first they told me it was because of dust. Second time ach we dind't find any issues. After one bloody year they found the issue; there was a small crack in a power supply cable. That caused sometimes weird issues with my pc


NOw for computer service i'm going to some bloody pawn shop with way bettter service, and much cheaper prices xD


Also check russel his comment, i think he is spot on what is causing your issue.

i'm not denying it in fact i sent my pc to the shop based on the fact it was a pc problem, he switched the psu again same problem, switched the gpu same problem, he even tested the game on his pc and took my save game as soon as loads outside of the bloody baron's keep it restarts the pc no blue screen no nothing and as i told you if you google the issue it happened to a lot of people, could be a virus or something else its just not a hardware issue sorry to break your logic, and as i said i've switched to dx11 and magically my the game is running 100% no crashes no reboots, if indeed it is a hardware issue it wouldn't just go away brother that's not how hardware works.

we don't have a maintenance guy it's a pc company and they found it strange too and told me if it happened again to bring it back, but for three days i've been playing non stop every game i have and no reboots, life is strange

The fact that you are able to run on DX11 but on DX12 it BSODs suggests that either PSU or motherboard might be at fault here. The videocards from big brands if they do not have enough juice usually beep (if manufacturer decided to spend about $5 extra on beeper), however depending on the load it might completely shutdown.

Not sure about your motherboard, however your PSU might not be enough for your configuration. There is a psu calculator on Newegg website and if you enter your CPU and videocard + 32GB ram + 1 SSD + 1 HDD it is recommending 800-899 Watts PSU... which is if you going to use a good brand PSU. I personally stayed away from PSUs that aren't made by the companies that just do PSUs so I cannot comment on MSI, however running 3080ti and Ryzen 1700X config I bought 1000 Watt PSU and never had any issues.

PS: you should test this on "heavy" games like Next Gen Witcher 3, CyberPunk 2077 (with recent update), Portal RTX or any other heavy release from recent years that is heavily utilizing RTX cores. Pretty sure if you check in Afterburner your power draw is much less in DX11 than in DX12.

It's not really the motherboard or the power supply that it the problem it's the 3080 and 3090 GPUs and the way the power delivery circuitry are designed that allow these current spikes (transients) to happen. I have also seen this same thing happen with RX 5700 XT in 2019 and an old game like Black Flag which isn't that demanding but in certain situations when hiding in a bush when the effect that makes a Brute light up to tell you he is in range for an assassination would cause the PC would reboot. For some reason it would cause the GPU current to spike high enough and long enough to trip the OCP. The solution was getting rid of the EVGA "White" power supply and replacing it with a good Corsair CX-650 M which is a very solid PS.

That's how I figured out the problem with that one guys 3080 and AC Origins. A couple of months later Steve posted this video which is a really good explanation of this behavior which has driven a lot of techs crazy trying to figure out and why I recommended it be watched

I'm basing this on years and years of experience and you cannot teach experience, you can only acquire it over time. The fact it is causing a reboot tells me it's the power supply tripping a safety and the fact that this is a Known Issue with the 3080 and 3090.

Also no one talks much about the fact that the 12V output is split into two different rails each handling 1/2 the rated output so balancing the GPU load across both rails is important with higher current draw GPUs. That's not a problem with his particular power supply which actually has the two rails marked with one rail supplying 2 "VGA1" labeled ports and the other rail has "VGA2" and the CPU and the instruction tell you how to make sure the load is properly balanced for 2 and 3 power cable GPUs. I suspect it's both the startup current of both the GPU ( VGA2) and the CPU that is causing the problem and a likely way to test for that is turn off the E-cores in the CPU which should lower the current draw and transients and if the game works then you have likely found the problem. I know a guy with a 13900K and a 4090 and he plays the game with the E-cores off and he gets better performance because the game doesn't properly thread on a normal CPU much less one that uses P-cores and E-cores which makes proper threading even harder because now you have to decide which thread need P-cores and which can get away with using an E-core (Although that part is handled mainly by Windows)

It seems like a shame to me to have a 3080 and not be able to take advantage of DLSS and Ray Tracing especially when considering DLSS Quality actually looks better than the native TAAU (Temporal Anti Aliasing UPSAMPLED). Both DLSS and TAAU are essentially TAA with upscaling with the difference being Tensor Cores do a much MUCH better job of processing the Temporal information than the other upscaling methods. While I don't have an AMD GPU to test it (Although I could get it to work with my 4070 Ti) I suspect FSR2 Quality would also look better than the TAAU CDPR is using which frankly is pretty crappy.
