Question Graphically demanding video games keep crashing on my new computer

[CheeseDecay333]

I recently made this custom build:


CPU | Intel Core i7-12700K 3.6 GHz 12-Core Processor
CPU Cooler | Noctua NH-D15S 82.52 CFM CPU Cooler
Motherboard | Asus TUF GAMING Z690-PLUS D4 ATX LGA1700 Motherboard
Memory | Kingston Fury Renegade 32 GB (2 x 16 GB) DDR4-3600 CL16 Memory
Storage | Samsung 970 Evo Plus 1 TB M.2-2280 NVME Solid State Drive
Storage | Kingston NV1 2 TB M.2-2280 NVME Solid State Drive
Video Card | Gigabyte GeForce RTX 3080 10GB 10 GB GAMING OC Video Card
Case | Cooler Master MasterBox NR600 ATX Mid Tower Case
Power Supply | Corsair RMx 850 W 80+ Gold Certified Fully Modular ATX Power Supply
Operating System | Microsoft Windows 10 Home 64-bit


The computer otherwise runs fine, but when I play graphically demanding games like Assassin's Creed Odyssey and Far Cry 5 for instance, the game will often crash and take me back to desktop. Twice I've had the computer completely restart as a result of a crash but mostly it just crashes to desktop. Typically within the first 30-60 minutes of gameplay or so.
I have been monitoring my CPU and GPU temperatures as I play (using Armoury Crate, a software that Asus wanted to install on my computer) and those temperatures are consistently less than 75 degrees Celsius. So I don't think it's an overheating problem.

Less graphically demanding games have not caused crashes so far.

I haven't yet tried overclocking anything.

Stuff I have tried:

I have installed the latest Nvidia drivers. Currently running "Geforce Game Ready Driver" version 511.79

I updated my BIOS to the latest non-beta version.

I tried swapping in my old graphics card (GTX 1060) which I know to be reliable. The same crashing issue occurred again so I don't think this is about my graphics card.


Photos of the build just in case that's useful:

Any ideas on what the problem could be and how to fix it? Thank you

Failure after a time smacks of a heat problem.
Likely with the graphics card.

I might suspect that the Armoury crate app might be involved, allowing the graphics card to run hotter than it should.
See what happens if you disable the app.

Monitor your temperatures with HWmonitor.
Look to see if your cpu ever reaches 100c.
If it does, that is the point at which the cpu will slow down or turn off to protect itself.
Many motherboard makers include as default overclock settings to make their motherboards look good.

Another possibility is that the psu has a problem with power draw spikes.
Here is a long post for you to look at:

My recollection is that the modern graphics cards like the 3080 will send signals to the psu that the psu can't handle.
The fix is a set of psu cables that does not pass on such signals.

Simplest thing to try: manually set all of your fans to 100% Maximum and see if that helps.

I turned on XMP and so far no crashes, I think that probably did it.
