Beast, I hope your still subscribed to this thread.
I've been having exactly the same problems for 2 weeks. BSOD watching anything flash in full screen, specifically hulu. its also happening in games too, like SC2, civ V etc.
After looking at your specs, we have 1 thing in common. our motherboards.
I've spent about 150 hours diagnosing / replacing / reinstalling to get a fix for this, the last straw was buying a new $200 power supply and it still didn't fix it. I'm now completely certain these gigabye boards have some kind of defect.
let me know if you make any progress with your issues, I'll stay subscribed to this thread and keep you posted if a new mobo fixes this issue.
