Flickering screen, no black screen.

[Silael]

Hello everyone ! here's my issue :

 

My screen is flickering, randomly, without any charge or any type of content to display, even on the windows login screen. It happened a while ago with my "old" 980ti and with this screen.That one time, going back to an older driver resolved the issue but it's back again and with another GPU. This time i've tried everything below and the issue is still here while I write this post.
Has anyone seen this weird behavior or even found a solution ? Can't find something that work on YT/reddit too.

 

 

Trying another GPU (1070ti EVGA [Miss them already]) -> Didn't work
Disable OC on GPU -> didn't work
Turning G-Sync on/off -> didn't work
Trying different refresh rate (120hz/60hz) -> didn't work
DDU and fresh install of drivers (from Geforce now and without) -> didn't work
Trying different drivers for both GPU and screen -> didn't work

 

I was thinking about buying a new one since this one might be getting old but I would like to keep it as second monitor to use it while streaming.

Ladies and gents, you are my last hope !
