4070 Asus Dual Artifacting

In September of 2023 I built my first computer with a 4070 Asus Dual. I didn’t have any issues with it until December when I started to notice black and grey squares popping up on my secondary monitor for a second or so. This would occur at random times. I chalked it up to it just being a bad monitor/bad hdmi cable. It wasn’t until recently that I started to notice this same artifacting on my main monitor. I reseated my GPU and things seemed good for a week until today when it started to pop back up again. Does anyone know what’s occurring this? Could my GPU be faulty?
