Gurus: This one is perplexing me. I just noticed this today, and it is a new thing for me. I have never seen anything like this in my years of PC building going back to the late 90s. https://i.**********/Mcjq3vKr/artifacts.jpg This is a picture of my second desktop, which is a 24" 1080p monitor turned 90 degrees. I think it is visible in the picture, but these artifacts change depending on what is happening on screen. I have installed the newest drivers for my GPU and it has not improved the situation. My gpu is used, and I picked it up from a business that was using it for cuda computing about 6-8 months ago. My current system: Asus Prime z270-k mobo i5 7600k GTX Titan 16 gb (8gb x2) gskill ram PC power and cooling 910 PSU I just loaded up Far Cry 3 Blood Dragon, which I was just playing the other day without issue and this is what I am seeing: https://i.**********/mPqtrPXT/blood-dragon.jpg Is this a GPU failing? Is taking it apart and fixing the thermal compound a valid fix, or are we past that? I just spend the early part of the evening removing EVERY Component from the PC and dusting it all out, and can confirm that everything is clean....there was very little dust at all in the GPU.
