ROG STRIX Z790-F GAMING WIFI - Computer Hang (black screen) issue

[Stapler_1994]

I have two systems with this spec:

Intel Core i9 13900K
Asus ROG STRIX Z790-F GAMING WIFI
128G RAM (2 x KF548C38BBAK2-64)
Crucial P5 Plus 2TB NVMe PCIe
Gigabyte GeForce RTX 4090 Gaming OC
Cooler Master MWE Gold V2 ATX 3.0 1250W
Win 10

So far I've done:

1. Reinstall windows
2. Update driver to latest
3. Update BIOS to latest (1303)

Nothing has helped. Also, interestingly, for diagnostics, I did the following:

1. Overnight memtest (from the BIOS - 3 passes, all OK).
2. 6 hours on Unigine Superposition + Haven benchmarks (No problems)
3. IntelBurnTest Overnight (No problems)
4. Furmark for 6 hours (No problems)

But still it sometimes crashes when playing games. When it does crash, the screen just goes black most of the time. Sometimes the fan will spin at full speed. There is nothing in the event log other than "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." Once, I got a blue screen that said bugcheck was: 0x000000fc or ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY.

Any ideas what this could be?

I'll chime in on this one.

Having exactly the same problem. Bios, reinstall, used known stable drivers. 

I RMA'd the 4090 but alas no fail was found. Not surprising given that i've already did a throrough check myself. 

I have not gotten a crash after updating the 4090 bios to v2.1, but I havent been long enough by the computer to be completely sure.

Yep, no resolution on this for me yet. Sometimes, I can run Furmark/Unigine for hours and its fine. Other times, it crashes when say watching youtube.

Anyway - About 24 hours ago now, I was having a look at the BIOS settings and I noticed PCI-e ASPM (and other related power saving settings) were set to disabled or off in BIOS, I have changed those to Auto (OS control). No issues yet so far.

@mrskadeskutt thanks for chiming in, that will be the next thing I try if I can't get a resolution. My intuition tells me this is actually a GPU issue. The other day, I uninstalled some apps and rebooted the system and got no video signal. When I plugged into the onboard GPU, I found the system was booted but the 4090 was not detected. I had to fully turn it off, unplug it from the wall, let it sit for a good minute and then turned it back on - everything was normal after that.
