One of my favorite things to do is to watch Leo Laporte’s TWiT network. On the website they offer a live feed which is great to tune into. The feed however requires Adobe flash to view the feed. When I tried to checkout the show on my work laptop, it would immediately BSOD my HP 8510p laptop running Windows XP SP3 x86. Unfortunately this would happen EVERY time I tried to view the show. Being a fan of Mark Russinovich’s ‘the case of’ blog series I thought I'd share how I identified the cause of the BSOD and ultimately how I fixed it.
To analyze the crash I had to install WinDbg which is installed with the Windows SDK. I downloaded the Windows 7 SDK and installed WinDbg . Before I installed WinDbg I needed to set my system crash dump settings to a create a full dump. On the System Properties applet select Advanced tab > Start and Recovery Settings > Kernel memory dump.
After configuring my crash dump I forced a crash by trying to view TWiT again, BOOM > BSOD.
Now I was ready to reboot and open the MEMORY.DMP file in WinDbg . The one thing you’ll need to do in WinDbg is setup the symbol server. 
SRV*c:\symbols*http://msdl.microsoft.com/download/symbols
Opening the crash dump showed me:
Probably caused by : ativvaxx.dll ( ativvaxx!vMMDLLInitFuncs+51a9 )
Ah ha! An ATI driver:

After I identified the cause I decided to update my video card drivers. So I went over to HP’s website and downloaded the latest ATI video card drivers and installed them.
After rebooting, the version of ativvaxx.dll changed from 6.14.10.161 to 6.14.10.0233 and viola opening the Flash TWiT live feed player did not crash my computer anymore! Now back to watching TWiT :-)
