I've been running my first homebuilt pc for the past few months and I'm suddenly dealing with desktop artifacts. I'm frequently seeing columns of very thin green lines on my desktop and while browsing. They are nearly unnoticeable, but I'm worried that my recent and first attempts at gpu tweaking with Trixx have damaged my gpu in some way. I've barely touched voltage and everything(games, 3dmark, gpuz stats) seemed stable at 1100/1600 for about a week(at stock voltage). I've recently set everything back to stock and I'm still getting consistent artifacts. All of my drivers are up to date. I'm getting 33c idle and 50c load temps. Being a tech noobie, I'm totally at a loss when it comes to troubleshooting this issue. I unfortunately do not have a separate hdmi cable, monitor, or gpu to test. I'm thinking of trying a clean system wipe as in act of desperation. I'd really appreciate any suggestions and if there is any vital info I left out, feel free to ask. Thanks
Update: Switched out to DVI cable and took out my graphics card. Still getting artifacts with integrated 3570k, halp! ;.;

Update: I recently completely disconnected my GPU from the Mobo and am now running a DVI cable to the integrated on my 3570k. I'm still getting artifacts. I feel slight relief towards the thought that it's probably not an issue with my gpu. But, now that I'm still getting artifacts using my integrated graphics as well as a discrete card, what is my next step in troubleshooting this issue?
I'll test a friend's monitor before I just go buy a new one, but is this the only possible issue now that the cables/gpu has been ruled out? Could it not be any other sort of hardware/firmware problem?
