Inherited grandfathers fairly new computer, now it's doing this shit. Pixels flicker everywhere, some are steady, horizontal lines appear...idk what the hell is going on with it. (Pic for reference)
Before you answer know this...
>it's not the monitor
Tried 2 different monitors, still does
>not the cables
Tried 3 different cables, even hdmi
>not improperly seated graphics card
Card is intergrated to motherboard
>not improperly seated ram
Reseated 3 times
Any ideas are greatly appreciated

What brand/model is your computer? What have you done regarding the GPU drivers?

What were your other cables?
To address your other ideas:
GPU: no, because of how the framebuffer is laid out physically, you get blocks not lines
RAM: no, because that would affect the stability of the computer. It wouldn't just keep running whilst the RAM was failing like that.
If it's doing it on every monitor, you've probably got a fucked display controller or PHY.
Integrated graphics doesn't mean every single part of the GPU is in your processor: that would be impractical. The pipeline goes something like:
[RAM] (on motherboard)
/\
||
\/
[GPU] (inside CPU)
||
\/
Display controller (inside CPU)
||
\/
[PHY]---> [socket] (on motherboard)
[PHY]---> [socket] (on motherboard)
[PHY]---> [socket] (on motherboard)
If it's the same failure on all ports with lots of different wires and monitors, then it's going to be a failure in a single component that touches all the ports which means it's the display controller in the CPU or the PHY on the motherboard.
You can bypass both of these by adding something like a GT 1030, and NVS, or any other random graphics card you have lying around. If you don't actually have an x16 slot, then you're going to have to test it with a known-good processor or motherboard.

Much appreciated anon, was thinking I might be able to just bypass with another graphics card
