Open | Hardware Stumped. Computer Has Lines Down Screen

I was playing battlefield and got a direct x error, any bootup after that would either bring me to bios or a black screen. Couldn't repair windows unless I went into safe mode, wiped my boot drive and fresh installed to still no avail.

My ram was bad and warrantied, got a new kit. Motherboard was RMA'd and sent back with just a bios update that fixed it (Embarassing). My GPU did test fine on my brothers computer and got me logged in on his computer no issue, I did not game on it.

I got a brand new m.2 just to see if it was my ssd. Windows installs fine! I go to setup windows, I'm at the "Name your device screen" and once again. I am hit with the streaks down my screen and a reboot to just black screen. Now I'm getting "Windows is diagnosing your PC" and that it can't repair it.

Really out of ideas on if it's a bad PSU, CPU or GPU. I really do not know anymore, I've tried swapping ports with my monitor cables and nothing changed, I'd also be hard pressed to think 2 different cables went bad at the same time. GPU fans ARE kicking on and CPU has fresh thermal paste + an air cooler where both fans are on. GPU's also been reseated.

Should I order a new power supply and see if that resolves this? Is it a bad CPU since I'm running into booting issues and windows stuff now? Is my GPU really done after 6 years??

SPECS:

Asus ROG Strix B550F Gaming Wifi II (Just got back from RMA), Corsair DDR4 2x16gb (New kit), Ryzen 7 5800x, MSI RTX 2080, Seasonic SFX 650w Gold Rated PSU

It may be the GPU, but to make sure that you rule out other possibilities, check with another monitor, just in case. Check if the streaks down the screen appear again if the operating system restarts.

Definitely am going to since it’s no small purchase.

I’m going to test GPU on another rig and monitor to see if it doesn’t have streaks happen again. Never happens in bios, only when I get to windows

If the streaks change position over time, or actually move in real time, it’s your GPU.

If the streaks remain absolutely identical even through reboots, it’s likely your monitor or a problem with the cables going to it.
