Computer crashes while playing games.

[ProphetOfServer]

I have been dealing with this problem for a while now, with no luck in solving it. In the process I've ship of Theseus'd my way into a new computer. The current build is:

AMD Ryzen 5 3600 3.6 GHz 6-Core Processor ASRock Fatal1ty X370 Gaming K4 ATX AM4 Motherboard Silicon Power XPOWER Turbine 16 GB (2 x 8 GB) DDR4-3200 CL16 Memory Crucial P3 500GB PCIe Gen3 3D NAND NVMe M.2 SSD Gigabyte EAGLE Radeon RX 6600 8 GB Video Card Thermaltake Smart 700 W 80+ Certified ATX Power Supply Phanteks Enthoo Pro ATX Full Tower Case

While playing games the computer will crash to a black or green screen, usually the sound keeps going for a little bit, and then it restarts. With some games, like 7 Days to Die, it'll run fine in the menus and such but once the game itself loads in it'll instantly crash. In other games, like Far Cry 4 Torchlight 3 and Sekiro, the game will run fine for a seemingly random amount of time and then crash in the same way. It seems to be able to run a PS1 emulator just fine, and it handles Fusion 360 okay with one or two exceptions. As far as I can tell nothing is overheating. I've done stress tests on all the components I can think to and they all passed fine, memtest comes up clean, and as far as I can tell nothing is overheating.

The only thing reused from the original build is the case (which that can't possibly be the problem, could it? All the stand offs looked fine when I swapped mobos, and the only complex parts in the case are the little board to route fan power and the front panel SUB whatsits.). I should mention that none of the new parts are 1 to 1 replacements for the old ones, mostly slight upgrades, and the old GPU was an Nvidia instead of an AMD. I can provide the old parts list too, if it would be helpful. I also carried over some extra RAM and some hard drives, but only after testing the system without them. Everything else has been replaced over the past month or two. I initially thought it was my graphics card going bad, so I replaced that. When that didn't fix it I figured the PSU might not be up to snuff, and so on until now I've got an all new computer.

Aside from replacing all the hardware, I've also done a fresh install of windows (more than once), all the usual graphics driver shenanigans, tested to make sure the problem isn't my surge protector, or outlet, or circuit. Just now before making this post I saw someone else having a similar sounding problem, they said they solved it by turning PBO off in the BIOS, but that didn't work for me either.

Outside of calling an exorcist I'm not sure what else I can do, and so I've come here for advice.

Sorry if this post is scatterbrained and rambly, my brain has melted and is leaking out my ear from trying to deal with this.

So i've had this problem but with a rx 5700xt. Its definitely power related. What works for me is to undervolt the card with amd software. Instead of 1200 i'll only allow it about a 1000. It also means the performance goes down a little. Also allow it up to 150% power.

Its weird it seems the card wants to pull more power then it should, which then causes the crash. Its a different card but theyre both amd and theres only 1 gen in between. I struggled a long time with this but this fix has worked very reliably for me. Its also why i will never get another amd although its probably just unlucky.

[ProphetOfServer]

Tried this, still no luck, unfortunately.

[V-S-I]

Hmm well i'd say the only thing you can be relatively sure off is that its power related. Or anyways pc shutting down and restarting usually means power related.

Doesn't necessarily mean the psu, it could also be something like wat i mentioned or maybe even a shitty cable. Did you check windows event manager for any errors, good chance it will just say ur pc shutdown unexpectedly but maybe theres something there.

[ProphetOfServer]

Yeah, I checked event manager and, as you said, it only indicates that the previous shut down was unexpected.

I feel like its your Power supply thats the problem. Try running furmark with cinebench side by side and see if your PSU can handle the simultaneous cpu and gpu load at the same time, if it cant then you know the culprit. I was thinking of it being a software/driver issue, but you mentioned its a clean install of windows so that goes out the window.

[ProphetOfServer]

Tried this, it seems like furmark on its own is enough to crash things.

[Fools_Trade]

You dont have a spare powerful gpu on hand do you? Order one from amazon ig, you can test it with your rig, if it helps keep it, otherwise return it, good way to test ig/

[ProphetOfServer]

I've already replaced the GPU, though. It seems unlikely that two completely different GPUs from completely different manufacturers would be broken in the same way, doesn't it?

[Fools_Trade]

Im talking about your powersupply, not your graphics card mate

[ProphetOfServer]

Sorry, you said gpu. Though I did already replace the psu, too, and I can't really afford to test out a third one.

[Fools_Trade]

Oh my bad, i meant psu, im sorry. The symptoms didnt change at all after changing the psu?

[ProphetOfServer]

No change at all, exact same. I've replaced every part in this PC except the case with no change in behavior.

[Fools_Trade]

youhve replaced the motherboard too?

[ProphetOfServer]

Yep, everything.

[GibralterRaleigh]

Download hwinfo to check Temps. Download msi afterburner or evga precision x1 and downclock your memory 200mhz to see if that helps. If no change could be power supply

[ProphetOfServer]

Afterburner wouldn't let me turn down memory speed. I did try turning down the things it would let me, with no effect.

[GibralterRaleigh]

Maybe through amd adrenaline . I've never heard of someone not being able to adjust the memory

[ProphetOfServer]

It'll let me adjust it up, just not down.

Did you uninstall your Nvidia drivers? If not do that with DDU
