"Guys I had exactly the same problem and I fixed it. ... You can use AfterBurner to control what app is allowed to initiate a powerstate change."
I found this forum, and I realize i'm not alone. This is card #3, as the first 2 gave me black screens, then BSOD. This one was working okay as long as i monitored it using GPU-Z. For some reason it acted okay when it knew it was being watched. Not anymore though, I have tried testing it watching a youtube video while playing a game (Crusader Kings II) and i can re-create the BSODs now.
How did you fix it, please step by step. I am familiar with MSI Afterburner, but only as a temperature monitoring tool.
If you can fix this problem you are amazing. Cause else, i'm ready to return this card and never... EVER... but a Radeon again. This will be my first, and last time.
Edit: My specs in case it matters (it doesn't, with my Geforce 480GTX I have never gotten a BSOD ever)
