Question Some black flashes while gaming (and browser letters failing too)

[mikaelsfm]

Good morning everyone

I've been playing Valorant and Hogwarts Legacy all week, no problems. Suddenly today, I opened Valorant and I see some flashes, like rendering failure and I have no idea what it could be, it's happening while gaming and watching videos.
I've already cleaned my PC, removed the dust, and it's still happening. Graphics are all up to date, everything looks fine.

I'm using a MSI Radeon RX 570, Ryzen 5 3500x, MB Asrock A320M.

Video of the problem here (it's happening in every game)
Also, sometimes elements from browser, like text and buttons also have some problems that I can't explain ...

Already tried another GPU, worked perfectly. With my GPU, switched RAM and the problem remains.

Your GPU might be dying. What you see there is artifacting and it usually hints at failing memory. Time for a new card.

After a lot of tests, that's what I narrowed down, though I'm living in full denial xD wasn't planning on spend a lot of money in a new gpu, but unfortunately I have no option
Thanks a lot!!
