I received a new laptop recently. I was bothered when it would show a Windows blue-screen-of-death (BSOD) about once a day with a message about ati2dvag. This was a Lenovo Thinkpad W500, which has an ATI Mobility FireGL V5700 driver. And it seemed to occur when I was doing scrolling or window resizing.

Unfortunately, updating the video driver from Lenovo didn’t fix it. Even reloading the OS from a factory image didn’t fix it. As was pointed out by a friend, here is what to do: open the Catalyst Control Center program, go to the PowerPlay tab and disable PowerPlay. That’s it. It hasn’t had a BSOD since. Thank you Mike!
