im not familiar with the "pda unpluged sound" , but usally windows will turn off the hd few seconds before or right after the bsod
get into c:\windows\minidump , rar or zip all files and upload to
http://www.mytempdir.com , those are bsod logs ill analyze the recent and let you know (and just to make it clear cuz some ppl dont get it right , after uploading you should provide the link)
as for the ROL demo , well its a demo maybe its a limitation on the other hand maybe just a bug its possible theres a patch/update that fixes it have a look
