Question My display acting a bit odd suddenly (turning on and off)

Aug 11, 2020
So for a couple months my display would randomly go black and come back again within a second, it doesnt happen that often so I kinda ignored it.

But today after turning on my PC my screen went black immediately and then proceeds to flicker white every 3 seconds (like its trying to get back on) and after a while, the display would be back but only for a few seconds.

I "fixed" this by taking just unplugging and replugging the power so it is fine for now but my question was, what could cause these issues and should I be more worried for later?

Sorry if the explanation is bad, I wasn't really sure how to describe it properly.

Edit: I use an Asus 24" 1080p 144hz screen
