temps GPU/CPU ? benchmark the SSD . Check Event Viewer for errors

Nvidia card? Users have started to report black screen issues since the last few updates

It's not an OLED Monitor is it? Some go dark "on purpose" as a feature supposed to extend life. But what your experiencing sounds more like a thermal or driver issue. I do know steam wont kill a tittle without an error message, nor will it crash your system on purpose. Normally if Steam has an issue with a tittle, it will simply fail to launch it.

EDIT if your loosing dig output, it's unlikely a result of anything Steam is doing.

do you still have sound?
does image return?
does the monitor say no input or its power light chnage?

what exactly do you do to fix it?

black screen can be anything, from bad leds on backlit displays (tn/va/ips), or with oled it can be the display driver board
on those the power light will not change and will not say no signal, and the pc will still work as normal

or psu, if the pc is rebooting with no warning or error log, other than unexpected restart


full specs would be helpful

post a cpuz validation link

cpuz -> validate button -> submit button
it will open a browser, copy the url (address) and paste it here

and psu brand/model/age

First try opt into Steam Beta in Client Settings and see if tnat fixes it.

May help to DDU wipe GPU drivers, reboot and install latest Motherboard Chipset and GPU Driver, reboot when done then configure GPU/Display settings as needed. Then retest your theory of it being a possible Steam issue.

temps are all good, it happens with my hdd and m2 ssd, event viewer is empty i think it doesnt really got detected as failure...

Yes i still got sound,
the image does not return, i once left it for like 5 minutes nothning happened
at first both of my monitors switch through hdmi and displayport channels and then it says no signal, then it shut off

the only fix is to reboot my PC with the start button on my case

there is no automated reboot since i think it doesnt even detect it as a fail, my psu got 850watts 4 year old acer PSU, i dont know the exact model because its a prebuild predator desktop pc

wow, acer made some bad decisions were made for the build
120mm aio on rear exhaust, those are worse than just a 120mm tower cooler
and a top 80mm fan, it looks like

why are the nvme drives marked as raid?
they all are different sizes, should be jbod,
but if the os is installed on one, just leave it, changing raid to jbod will unformat it

stock shows the 2tb sata hdd?

it could be the nvidia drivers causing the problems, people have reported black screens with them
get the oldest nvidia driver available

https://www.nvidia.com/en-us/drivers/details/245376/
newer drivers only have fixes and optimizations for newer gpus, not older gens
do not use windows update or nvidia app for driver updates

Look in Windows Logs > Applications within Event Viewer. It can't be empty unless you are deleting the logs or using an app tbat wipes that out like CCleaner

i d try only with one monitor , less drives .also would try with a spare GPU . also check cables and so on

It sounds like OP is experiencing that bug we were having with Steam Overlay and such. But it should be fixed now. But ensure you are using Steam Beta. You can change this in the Client Settings

I had 4 Acer monitors and they all behaved like that after awhile in use, bad power switches I believe, got rid of them and will not buy another.

fw its worth - the fix for me was to pull plug at rear and reconnect, then turn them back on and they were usually ok for a while.

You will need a graphics card and not a gafics card. That will solve your issues.

what monitor are you using?

EDIT if your getting sound and no events in viewer, it sounds like what an OLED will do to fight burn in (often in the 5 -10 minute range). Or a cabling issue (it would be odd if the monitor isn't telling you it's doing it however) Did you try cycling the monitor power (not the PC)?
EDIT never mind I see you said it reports lost signal, check cabling. Any kinks? sharp bends? high tension? wear? dusty contacts?
