GPU artifacting typically means one of the four things, in the order of severity
Cable is fucked
Monitor is fucked
GPU drivers are fucked
GPU itself is fucked.
To test 1) try changing your refresh rate and resolution to see if the artifacting occurs similarly. If it ceases, change your cable. If one of your monitors displays properly and another monitor artifacts, this is also the main culprit
To test 2) plug in another device that uses the same port your PC uses. If you see similar artifacting, change your monitor
To test 3) try booting your PC off of a live USB with any OS. If you don’t see artifacting, you’re gonna need to change your GPU drivers. Refer to your OS’s documentation on that, not me please.
This step also tests for 4. If you see artifacting, it’s highly likely that your GPU is fucked. Try disconnecting the GPU and use the integrated graphics if that exists, or an old GPU. Use that as a temporary solution until you upgrade your GPU.
