Hello! So, I'm posting here after 2 straight weeks of almost no sleep trying to fix this..

I get White/grey flashes that only take half a screen when I play Valorant, League of legends or sometimes when I alt TAB or watch youtube videos... They are very fast, hard to see actually at 240HZ. I've tried:

1. Changing monitor,
2. Changing the Display Port cable, (For a certified one).
3. Changing the GPU.
4. Reinstalling drivers like 5 times with DDU.
5. Reinstalling the games.
6. Reinstalling Windows (10 and 11),
7. Reseating the RAM (with one stick or the other stick in single channel too),
8. Freesync ON/OFF
9. SAM ON/OFF

Things I haven't tried:

1. Other PSU.
2. Other motherboard.
3. Other CPU.

Everything is brand new and within warranty, I just need to know what's the issue so I can warranty the specific component! :/ I have no idea what else to do.
