AW2518HF, Nvidia RTX 3080, black screen/blinking

Hello,

I have been having some issues with my AMD FreeSync AW2518HF. Randomly my AW2518HF will black screen for about a second and return back to normal. Sometimes these black screens happen a few seconds after each other and sometimes it won't happen for a few hours. At first I thought my DisplayPort cables were bad so I replaced those and the issue persisted. Next I made sure all cables inside my pc were secure including re-seating my gpu. These issues started a few months ago and my AW2518HF is past its one year warranty. Does anyone have any ideas on what may be causing these issues?

PC Specs: Ryzen 7 3700x / RTX 3080 / 32gb 3200mhz DDR4 / B550M DS3H mobo / 500gb M.2

Thank you in advance
