Is there any way to stop this seemingly endless GPU "power cycling" when I've left my computer unattended with no GPU load and the screen has turned off? I'm using Windows 8 (yes, the problem happens in 7 too before anyone points their finger) and this problem is annoying because the fans on XFX cards make a horrendous "jerking" noise when they power on and it is annoying as **** to hear it happen EVERY 5 SECONDS while I am trying to sleep. I finally got a screenshot that describes what is happening, so any suggestions besides turning the computer off at night are welcome.
I'm also getting random "BSODs" that either occur once every few days or several times a day in some cases, and all of them show up in the Event Log as "Critical Kernel-Power Event ID 41 Task Category 63" stating that my computer didn't shut down cleanly. Happened on my 2600K + Z68 mobo + different PSU so it probably isn't any of those things. Anyone else getting these?
