just guessing but one never knows: just from my own very recent series of unexpected White Death experiences (and your systeem looks like mine, and so does your use of it):

Do you have a Crucial-4M SSD installed? Has it made about 5184 duty hours? Then it will generate WSoD's every 55 mins until you feed it the latest (000F) driver. It;'s not Poser at all.

When on Win7, get the Win7 installer from their website, unpack it onto your Desktop (and nowhere else!), read the guide, run the firmware updater, and you'll be fine. When not on Win7 get the stuff for the driver-update-CD, burn the iso onto it (on CD R only, no DVD, no rewritables!), run the stuff and you'll be fine.  At least I am now.

best luck

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
