    PC shutting down - please help me

    So since I've been playing 7dtd on PC, my pc has been shutting down and rebooting. Its sporatic.
    Ive checked memory, turned off fast boot, all drivers/bios updated/pc on a 900W UPS.

    i7 9700k, 16gb ram, 2070super. This has been happening since alpha 17.4 (when i started playing on pc from ps4).

    Either the issue is one of two things. The game is somehow causing crashes and reboots or its the PSU. Has anyone experienced the game completely shutting down and rebooting? Please advise thank you.

    No, do some stability testing, prime95 with different settings and so on.

    I had something like this too some month ago. It was the PSU, after upgrading my GPU all would run fine, but after sometime ingame i had a instant reboot. After changing the PSU and upgrading it the problem was gone. Happened always ingame.

    It was no shutdown but PC instantly shutting down and rebooting.

    You might want to test another PSU.

    I did occt testing on CPU and GPU, no errors, no issues with temps either

    I appreciate it, I think I've ruled everything out aside from the PSU

    stresstest cpu+gpu, then you will see if you have thermal or power issues.

    that you have no issues when you test both separate, does not mean, that you will have none if both gets tested simultanously.

    e.g. start up prime blender with not all threads (leave 2-4 free) and punish the cpu with something else. (eg. valley)

    random reboots, there is one thing that I have seen that can cause this is, the capacitors on the CPU going bad, it depends on the type of capacitors on your main board, are they metal cans or plastic, see if any of them are bubbled out. if there are any that are obvious then it could be a bad capacitor. Checking the PSU is also a good suggestion, do you have a PSU connection to your video card, a good idea is to reseat the card and power connections.

    Try a Memtest to see if the Ram is stable. Also, 1 benchmark / stress test doesn't prove it's stability as they all stress things a little differently. Were you playing on SSD or HDD? What model number is the PSU? PSU's usually fail in a more predictable way, so I don't think it's that, but knowing the model number and looking up info might help prove it's innocence in this.

    I haven't seen leaky capacitors on a motherboard in over 10 years... I guarantee it's not that.

    If the problem is the Power Supply, you can try to reproduce it like this.

    Run Prime95 and set it to 4 cores. (4 of your 8)
    Then run Furmark at the same time. Make sure you don't have any
    frame cap on v-sync stuff on. You want maximum fps in Furmark.
    (you should be well over 200 FPS in Furmark)

    Monitor temps while doing this. Record them.

    With both probrams running at the same time you should be stressing your
    system enough to cause a shutdown or reboot if your Power Supply is weak.

    If it doesn't shut down, then I think the problem lies elsewhere.

    The problem with running multiple stress tests at the same time is that the results can be unreliable and vague as to where the problem is. That's why PSU is always the last thing to test. You have to be completely sure that nothing else is failing, by then, you shouldn't even need to run a test for it.

    There's also some tests you could run while using Hiren's boot CD. It's free and has various programs for testing the motherboard, CPU, GPU, RAM, HDD, and I think maybe also PSU, but don't quote me on that last one. It runs better in DOS mode.

    Not really interested in reliable results with my test suggestion. The point is to max out power use by both the cpu and gpu at the same time, which it does.

    I've done a few things

    I ran a cpu load for an hour on occt - no issues
    gpu load for an hour on occt - no issues
    PSU loaded for 15 minutes - no issues other than ♥♥♥♥ was starting to get hot.

    Then during 18.1 b6 what was happening was the game was locking up every 15-30 minutes. couldn't get to task manager, and i was still having the issues with the pc just shutting down and rebooting.

    I turned settings down to 1080 on high settings, fps is like 120-140. So far the game has not locked up and hasn't rebooted. But usually the rebooting would happen after 2-3 hours of playing and I haven't played that long yet.

    So now I don't know if the issue is the GPU or PSU.... ???

    Did you try stressing both the CPU and GPU at the same time? That's the only way to
    test the power supply in software.

    The 2070 would use less power on the lower settings, so I still think it could be power related.
    If it's not the Power Supply, maybe it's the 8 pin connector to the GPU.
    Maybe its loose or not making a good connection. Try a different cable maybe or re-seat the
    one you're using. I'm assuming a 900 Watt supply would have more than one 8 pin connector.

    So I just started playing the outer worlds on 1440 ultra, no issues so far - I would have on 7dtd for the duration I had played... I don't know whats causing the issues on 7dtd??

    Like Beelzybub said, it could be the power supply. Testing another game and not seeing the issues or lowering the details/resolution will not help you. Test the PSU - Borrow some and test it. You are circling around that issue.


    How old is your PSU ? Which manufacturer ? What are your complete system specs? There are help pages that can calculate your PSU needs for the system. If its already on the edge, an older PSU can make the small difference of one game running perfect and the other one shutting down. Cause PSUs get worse over time. cheap PSUs tend to give less power then they pretend to.
    If your PSU is 4-5 years old it may only have 90% of its values, if it was a cheap one maybe it had never that much power that was pretended.

    Be Quiet PSU calculator: https://www.bequiet.com/en/psucalculator

    There should be some others around too.

    You could do the stress test that I outlined in my original post.

    Prime95: https://www.mersenne.org/download/
    Furmark: https://geeks3d.com/furmark/
    hwinfo: https://www.hwinfo.com/download/

    Use hwinfo to monitor temps during the test to see if that is the issue.
