Valheim keeps crashing PC.

[Joey]

Sometimes I'm able to make it up to an hour but the game always crashes my PC eventually and then I lose tons of progress. There are many stacks of finewood, iron and copper that have been lost like tears in rain due to Valheim crashing my PC.

I play many other video games and do plenty of other projects on my PC. It only crashes when I am playing Valheim. What's the problem here?

We don't know until you post the crash logs and do the following:
1. Uninstall your mods.
2. Update or roll back your graphics drivers - use DDU to clear them out.
3. Sometimes it's necessary to reinstall your audio drivers
4. Type these in an admin command line window

DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow

This will check windows for corruption and hopefully fix it. You may need to restart for many of these fixes.

Those are just basic troubleshooting. We can't know the exact cause without a crash log or windows log.
If it bluescreens, make note of the error code and/or filename it shows. If it doesn't, it's a driver issue that is crashing hardware forcing the computer to turn off to save itself.

The game log files are here (probably, I haven't crashed so it's not there):
%localappdata%\Temp\IronGate\Valheim\Crashes

Windows Event Viewer is here:
Start -> Type: event -> click the Windows Event Viewer entry
Go to the System category on the left.
Click on the heading for Level in the table to sort by event level, you want to see red (!) exclamation points that say ERROR. You will have to use the scroll bar, windows 95 interfaces don't auto return to top on changes...
You can right click on the System category and select Clear Log and then crash the game and see which entry is produced - after restart.

If no crash event is logged, it was a hardware issue that caused the bios to shut the computer down for protection. Probably your graphics card drivers, if so, you'll have to find a driver that doesn't crash. The newest drivers usually are the best, but not always, sometimes you'll find a bad one for specific games.

valheim sometimes runs flawlessly for hours, but since the mistlands update it crashes my entire system. only game i can remember to crash my entire system. makes absolutely no sense.

Same issue. Since the update, run for hours then crash

I wanted to try out the new update today~ and had the same issue.
Before the update everything where fine, just played with a few Friends and Solo. But now i had 2 full crashes. First time i thought my mods where not up to date, but nope even whitout mods and starting a new world after 1 h shutdown.

I don't have a crash log in the mentioned Save and also WIndows just gives "kernel error" aka an error shutdown.

Figured mine out.

Same issue here. Valheim randomly crashes since Mistland, it also takes Steam with it every time.

After a few months suffering from crashing in Valhein and researching in dozens of communities, and hearing from Unity developers that the problem was on the PC and not the game, I finally found the solution at this link:

https://www.reddit.com/r/valheim/comments/mlfm3q/blue_screens_crashes_my_fix_01487/?onboarding_redirect=%2Fr%2Fvalheim%2Fcomments%2Fmlfm3q%2Fblue_screens_crashes_my_fix_01487%2F

The problem in my case is that the crappy Unity has a problem with Intel Turbo Boost, when disabling this option in the motherboard Bios the crashes never occurred again.
As a guarantee I disabled all overlays too, from steam, Nvidea and etc.
So devs, obviously the problem with hundreds of thousands of people complaining about games made in Unity randomly crashing is not their computers, it's the crappy Unity.

If a SOFTWARE causes your HARDWARE to crash because of the HARDWARE's automatic overclocking what's at fault again?
Right, it's the hardware Pretty sure by today's standards[1] it's the hardware (or its drivers/firmware) that can't handle completely normal demands of a game(engine) which runs perfectly fine on thousands of PCs...

And it might not even be Intel's fault if your systems cooling or PSU or voltage regulators are insufficient.


[1] code not really running on bare metal, without root/admin rights, drivers/etc catching illegal operations (eg. div by zero) and only crashing/stopping that application but not the whole system.
