Hello everyone, first post here.

I had the 3090 FTW3 for around 3 days now and just this morning, while I was playing the Witcher 3, my screen went black with the gpu fans stuck at what sounded like 100%. Prior to crash, I was monitoring the temps and the highest it reached was 73 C. It appears that the PC boots all the way to desktop as I hear a custom startup noise I set using a pair of headphones plugged into my sound card. I heard these issues may have be related to NVIDIA's drivers so I thought a simple restart would get it up and running again. Boy was I wrong. Its been 10 hours of endless troubleshooting with what ultimately led to a call to EVGA and a RMA started. I tried different monitors, different video cables, reseating the gpu, resetting the cmos on my mobo, trying it in a different pc, all in vain. I swapped in my old 1070 and all is working again. Has anyone ran into this issue. What are the chances that this will happen again when I receive my replacement gpu?

Of note, I do use a riser cable with PCIe 4.0 compatibility for vertical mounting. No issues for the first 3 days on the 3090 or now with my 1070.

The psu I'm using is listed below, and the whole system is around 8 months old.

 My specs are:
PSU: Thermaltake toughpower grand 850w
CPU: Ryzen 3950x, cooler: Corsair h150 AIO
RAM: Trident Z Neo 64gb at 3600 Mhz
Storage: 2x Samsung 970 500Gb
Mobo: Asrock Taichi x570

If I do see an error, what can I do at that point? I know it depends on the error, but I want to know possible options.
 
Thanks for the reply.

Man.. Looks like this issue is getting bigger then previously thought (same thing happened to my 3090 btw and had to RMA).. I'm starting to see posts about the same issue on reddit.

I'm wondering if owners of asus tuf or MSI or FE have similar issue or if this is strictly EVGA related 

Single red light on the card?

For me it had nothing to do with my psu. I ended up buying a new 1000 watt platinum and still had the same problem..plus my older card is working fine right now without any issue

Same thing just happened to me yesterday. Booted up a game and after about 15 minutes of playing, black screen with no display signal detected to all of my monitors, and GPU fans at 100%. Rebooted, and there's no display, but you can hear the sound if I have my headphones on. Tried pretty much everything I can think of, different psu cables, different computer, different PCIe slot, tried reseating it in the original slot, absolutely nothing worked. Very aggravating since I hadn't even had the card for a week and it dies on a holiday week as well. Luckily I still had my old GPU, but kind of crazy that these cards are just dying so quickly like this.

The only time I've seen the machine go black was from exceeding PSU limit. Perhaps a PSU issue?

Its definitely not a PSU issue.  I tried the GPU after it died in 2 other PCS and same thing, just a black screen and POST failure.  Plus my Corsair AX1200i is more than capable of driving this card.  The store also tested card and confirmed she was dead, so I got a replacement card.  Day 8 with it, so far so good.
