Question Is my GPU dying?

[karolm]

Hey i have weird problem. Last weekend i was playing games on my computer and my main monitor just turned off after around 10 min of swaping cables i was able to get the screen back on. everything was working fine next day i did turn on and off few time tho but only for few seconds. Today i could not get the monitor to turn on at all, to be clear i am taking about main monitor i am running 3 setup monitor and other two are fine. after 2 h and complete windows wipe iwas able to get it back up but now it flick off and on almost every 1min or so also relized i cant push the monitor up to 240 hz for some reazon it doesnt accept it i can be on 144 hz. I tried difreent cable it didnt work wipe of windows didnt work tried swaping to old monitor also doing same thing . While other 2 monitor are running complete fine this one is still turning on and off and i am not sure why. Do you think it migh be my gpu dying and not handle 3 monitor at the same time anymore ? i have GTX 4080 btw been playing on this comp for around year with no problem. And also tried unplugging one of the monitors by main one still flickering . GPU TEMP is 40c btw

Gpu is not dying, otherwise other two monitors would be having issues as well.
Could be a monitor, cable issue.

I connected same monitor with different cable but same issue. Also had old monitor and connected it and same problem . That what I was thinking first that It had to be monitor but after connecting old one that I know it worked and had same problem I do not know anymore.

Could be the port on the card dying, I've had that happen before, try using one of the other ports and see if the same thing happens.

Like I mentioned before tried swapping ports and nothing
