Guys I'm having a serious issue and I need help. It is about my GPU.
I have a 6950 connected via displayport and I am getting seemingly random flashes of artifacts that last a brief moment. The artifacts do not cover the screen, they vary in height, but do stretch all the way horizontally. And this artifact bar is not always in the same spot. It is happening every few minutes. I have also experienced my screen blacking out for 2 seconds or so and then coming back on. I have not played a single game, this is all in windows environment.
More information: I am running Win7 x64. I just put my rig up last night. First I installed my drivers (Catalyst was the last thing I installed, even after doing windows update). At this time, there was NO graphical errors. Windows was running without any display drivers, so it was at its default res, but there was not a single instability in graphics display ( I was on the computer installing various programs for more than an hour before I got to installing catalyst drivers). After installing catalyst drivers, I installed MSI afterburn. I then followed a guide to unlock shaders on my GPU. My clocks were increased and my voltage went up. I don't remember if I saw artifacts when I finished that, because I was barely awake at that point.
Today, I was noticing the artifacts and I thought it my voltage. I put it to stock 6950 voltage and it was not helping. I put my GPU at stock clocks and nada. So I reversed the process, which involved disabling some setting in ASUS SmartDoctor (this program was used in the unlock guide I followed), then flashing my GPU back to my original bios (which I had backed up). This was successful in restoring my GPU, but the problem persisted. So I used driver sweeper to uninstall my AMD display drivers, shut down the computer -> Opened my case to check the GPU connection was fine (it was, but I took it out and put it back in to be sure) -> Booted Windows with no display drivers (I noticed no artifacts, but I was only driver-less for a few minutes) -> installed AMD catalyst drivers (latest stable) and rebooted. It has not helped. What the fuuuuuuuuu
All fans in my case are running btw.
