I had to underclock my old GTX970 to avoid getting black screens after a certain time :( 

Update on my issue with the RTX 3070. I encountered a signal drop again after turning the display off for a bit then back on, but the issue went away after plugging into another display and using DDU to uninstall drivers, then reinstalling. I think this simply reset the settings for the display having the issue.
 
My display that would lose the signal is an LG OLED C9. I replaced the HDMI cable thinking the cable was having the issue, but I saw the new cable lose signal once as well. I've been running 2560x1440@120Hz with 4:4:4 chroma. The TV does not allow these settings unless Deep Color (HDR) mode is enabled on the HDMI port. So the next time I lost the signal I disabled Deep Color, signal came back (but not allowing my settings), then I re-enabled Deep Color and got back the signal with my settings. Signal loss is very rare now (only one time) with the new cable, but I think just toggling that setting on the TV on/off should get the signal back if it happens again.
 
Still not entirely sure, but it seems it could be my TV being flaky or the HDMI cable. At least I didn't have to uninstall/re-install drivers last time the signal was lost. I just toggled that Deep Color setting and waited for the TV to restart which is mildly annoying, but far less hassle than switching to another display and re-installing drivers just to get the signal back. The previous HDMI cable was doing it more often. It's not entirely resolved, but it's very rarely happening now.

Win 10 now do some stupid things. Ask me to restart and update, then back and try again and again.

Hopefully this fix works for the people having issues

It definitely fixed the issue for me on the one system that was having this issue with my 3080. My other one with the 3070 luckily was unaffected.

Got a brand new FTW Ultra Gaming 3090 today. Was 10 minutes old when it stopped working. Didn't even get to do anything. Installed drivers and changed colors. Restarted PC and poof. No post. No signal to monitors. Motherboard error 97. Old video card works just fine. $2,000 and I didn't even make it past driver installation. Waiting on a response to my ticket. I'm really nervous about my EVGA card now. Hope they make this right.

This scares me

Hi guys,
 
I'm having the same trouble so far. I've updated my ASUS bios, my GPU firmware and downloaded the latest NVIDIA patch even though i'm having black screens.
According to me, these crashes happen due to high frequence demand for GPU clock and memory clock. But, since i've put my GPU into "Boost Lock" in the X1 EVGA software I haven't got any crashes because the clock is maintained at the hight clock as it could be for benchmarking. I've not noticed any GPU temperature trouble, would it damage the GPU if i continue doing so ? Because i've not find any better solution yet.
 
Thanks guys

 Oh man nooooo! I sold my RX 5600 xt last year because I had black screen bug I could not get rid off. Dont tell me 3000 series has same issue..... :/

i finally stopped getting black screens after installing the rebar driver.
 
after installing precision x1.1.9. and updating the firmware, I'm getting black screens consistently again.
 
when updating the firmware my gpu fans rev'd up super loud for some reason but still updated in the end.
 
This is some bull****...

I ran into an issue with the Windows 10 update last month in which it installed fine, and after rebooting, the Windows splash screen was just black with a mouse arrow and a spinning wheel above it.  I had to reboot several times just to get into the system recovery mode and perform a system restore from the day before.  I thought that maybe the Windows Update somehow messed up my video drivers but now that everything is working, I am not sure what the issue was.
