Hey everyone, thanks in advance for reading this - it's been a frustrating past day or so trying to deal with this issue; I'll try to give all the details I have regarding this problem but I'm sure I'll forget to add something, so just let me know if I forgot something critical!

I have the GPU stated above. I built a new rig on Friday and went through the Windows installation on Saturday. All was dandy until I (in hindsight, stupidly) took the CD that came with the GPU and inserted it into my disk reader. I'm not sure what exactly happened, but this coincided with the first incident of the problem I'm now struggling with. Basically, display output (through HDMI) to my monitor craps out, sometimes by outputting a single, seemingly random solid color (it was usually red or a shade of blue at first, now sometimes it just turns to black) or a flashing screen. The first few times I had this problem, I didn't think it was a big deal, because upon rebooting I was able to get past the logon screen and actually function for a reasonable amount of time (2 hours?) before the problem happened again. Another crash occurred, for instance, not while playing a game, but right after I exited the game window.

Now, however, I'm not even able to get on to Windows - the problem usually occurs right after I sign on. It says "Welcome," and then outputs the crash screen almost immediately afterwards. I tried un- and re-installing the drivers while using integrated graphics on my i7-4790k (which worked for a while, but for some reason is now not outputting...), which did not solve the problem. I used Display Driver Uninstaller a couple of times as well. Installing previous drivers did not help, either. At this point, I was able to run in Safe Mode, but after the integrated graphics stopped outputting to the display, I wasn't able to boot to SM.

A few hours ago, I re-installed Windows, which allowed me to successfully operate again. The first thing I did was install the GPU drivers, via Windows Update. As soon as I restart, bam, the problem returns. I've googled this issue, and it seems like several people with this specific GPU have also had this problem, but it's unclear to me how to solve it. It looks like people with the 2GB version of the card updated the GPU's BIOS and that solved it, but there is no BIOS update for the 4GB version.

Any help would be much, much, much appreciated!
