anyone here have any experience with the 'White Screen of Death' phenomenon?

I get that behavior occasionally (but not nearly the frequency that you mention). I'm running Win7 x64, and I see such behavior probably not more than once a week. It typically occurred in Firefox, but sometimes also in Outlook (2007).
I might not see it as much as you do because most of the time I'm in a text editor, serial port terminal window, or a VMware session.
I'm generally reluctant to upgrade software, so until recently I was running some old version of Firefox (I can't remember what version exactly, but something in the 4.x - 11.x range, I think). I always assumed that the problem was either because of FF or because of antivirus software.
I restart my Windows box pretty much only when absolutely necessary (usually due to updates) about once a month, and Firefox maybe once every couple weeks. I also keep about 50 tabs open in FF. So by the time I'd restart FF, it would often have gotten pretty slow and be chewing up a huge chunk of memory. The AV on this machine (it's managed by an IT department - also it's McAfee

) also has various processes that seem to occasionally peg a CPU core, so I have to use task manager to kill those every now and again.
Anyway, the bottom line is that I always assumed that the "WSOD" problem was either FF or AV instability. As a side note, FF 17.x is a big improvement stability-wise so far.
