Working on a friends computer which is having some green horizontal line artifacts showing up as soon as the monitor received a signal. The arrangement of lines change when/where things change on the screen. See images below for visual artifacts. Along with these artifacts, the computer occasionally BSOD.
What i have done:
Used different dvi cables/ports
Used different monitor
Updated BIOS
Updated GPU Drivers
reseated GPU in PCI slot.
GPU does not work in the first PCI slot (issue came up a couple months after getting this motherboard which replaced its original) and has been running on the second available slot.
I am about to take the GPU out and plug it in to my computer to see if its the GPU, i suspect its the motherboard.
ok, pluged it in to my computer and ran it form my computer, artifacts are still there, its the gpu. i avoided doing that sooner because its a bit invovled to take out my gpu, otherwise that would have been one of the first steps.
that also works... just strip the card down put it in there FACE UP on a level surface that won't melt to it (like balled up aluminum foil as stilts works) 10 minutes at 345 degrees., let it cool off reinstall tada. there's more in depth tutorials but that's the jist of it.
I already decoded it, it says put me in the toaster. seriously though the uniformity and low load artifacting makes me think re soldering with the toaster will fix it, core related artifacts aren't nearly as pretty.
Bonus image. I had to use a dagger to unhook the PCI slot latch because it was the only long thin thing i had, otherwise id have to take the CPU heat sink off to get to that latch.
