Both of those BSoDs were caused by bad memory, so I suggest running MemTest86+ for a few passes to make sure your RAM is ok: Check your RAM
Also, these drivers
should be updated:
secdrv secdrv.SYS Wed Sep 13 06:18:38 2006
WinRing0x64 WinRing0x64.sys Sat Jul 26 06:29:37 2008
usbaapl64 usbaapl64.sys Tue Sep 16 09:08:03 2008
You should update your Motherboard drivers, as well as the rest of your drivers.
iTunes 8 coupled with the usbaapl64.sys file seems to have created BSoDs in the past, so make sure you are using the latest iTunes.
